ResumoIn this work, we present a study of the coronal mass ejection (CME) dynamics using LASCO coronagraph observations combined with in-situ ACE plasma and magnetic field data, covering a continuous period of time from January 1997 to April 2001, complemented by few extreme events observed in 2001 and 2003. We show, for the first time, that the CME expansion speed correlates very well with the travel time to 1 AU of the interplanetary ejecta (or ICMEs) associated with the CMEs, as well as with their preceding shocks. The events analyzed in this work are a subset of the events studied in Schwenn et al. (2005), from which only the CMEs associated with interplanetary ejecta (ICMEs) were selected. Three models to predict CME travel time to Earth, two proposed by Gopalswamy et al. (2001) and one by Schwenn et al. (2005), were used to characterize the dynamical behavior of this set of events. Extreme events occurred in 2001 and 2003 were used to test the prediction capability of the models regarding CMEs with very high LASCO C3 speeds.

ResumoThe horizontal component amplitudes of magnetograms recorded by ground-based observatories of the INTERMAGNET network have been used to analyze the global pattern variance of the solar diurnal variations. Those kinds of data present gaps in records and consequently we explore them via a time-frequency gapped wavelet algorithm. We propose a new approach to analyze magnetograms based on scale correlation. The results show that the magnetic records have a latitudinal dependence affected by the season of year and by the level of solar activity. We have found a disparity on the latitudinal response at Southern and Northern Hemispheres during solstices, which is expected due to the asymmetry of the Sq field. On the other hand at equinoxes, records fromstations located at approximately the same latitude but at different longitudes presented peculiar dissimilarities. The achieved results suggest that quiet day patterns and the physical processes involved in their formation are strongly affected by: the conductivity of the E-region, the geomagnetic field intensity and its configuration, and the thermospheric winds. Keywords: Magnetogram.

ResumoGPS time synchronized high-speed video records (at 4000 frames per second) and electric field waveforms are discussed for one stepped leader of a negative cloud-to-ground flash whose initial development becomes visible above cloud base. The leader emerges from the opaque region of the thundercloud around 4800 m above ground, propagating with speeds of the order of 106 m s -1. It is possible to see that this early, bright, and fast propagation period occurred simultaneously with the emission of initial breakdown bipolar pulse trains. The leader gradually reduces its speed and luminous intensity: When its tip is less than 3000 m above the ground, the propagation speeds oscillate between 2 and 4 × 105 m s -1 until it makes contact approximately 16 ms after it first became visible. With time, the initial breakdown waveform is gradually replaced by unipolar pulses and the leader propagation speed drops to the 105 m s-1 range. Key Points Fast visible leader development during the initial breakdown pulse activity Breakdown bipolar pulse trains become unipolar as the leader slows down.

ResumoThe interplanetary causes of 213 moderate-intensity (-100 nT < peak Dst <= -50 nT) geomagnetic storms that occurred in solar cycle 23 (1996-2008) are identified. Interplanetary drivers such as corotating interaction regions (CIRs), pure high-speed streams (HSSs), interplanetary coronal mass ejections (ICMEs) of two types [those with magnetic clouds (MCs) and those without (nonmagnetic cloud or ICME\_nc)], sheaths (compressed and/or draped sheath fields), as well as their combined occurrence were identified as causes of the storms. The annual rate of occurrence of moderate storms had two peaks, one near solar maximum and the other in the descending phase, around 3 years later. The highest rate of moderate storm occurrence was found in the declining phase (25 storms year(-1)). The lowest occurrence rate was 5.7 storms year(-1) and occurred at solar minimum. All moderate-intensity storms were associated with southward interplanetary magnetic fields, indicating that magnetic reconnection was the main mechanism for solar wind energy transfer to the magnetosphere. Most of these storms were associated with CIRs and pure HSSs (47.9\%), followed by MCs and noncloud ICMEs (20.6\%), pure sheath fields (10.8\%), and sheath and ICME combined occurrence (9.9\%). In terms of solar cycle dependence, CIRs and HSSs are the dominant drivers in the declining phase and at solar minimum. CIRs and HSSs combined have about the same level of importance as ICMEs plus their sheaths in the rising and maximum solar cycle phases. Thus, CIRs and HSSs are the main driver of moderate storms throughout a solar cycle but with variable contributions from ICMEs, their shocks (sheaths), and combined occurrence within the solar cycle. This result is significantly different than that for intense (Dst <= -100 nT) and superintense (Dst <= -250 nT) magnetic storms shown in previous studies. For superintense geomagnetic storms, 100\% of the events were due to ICME events, while for intense storms, ICMEs, sheaths, and their combination caused almost 80\% of the storms. CIRs caused only 13\% of the intense storms. The typical interplanetary electric field (Ey) criteria for moderate magnetic storms were identified. It was found that similar to 80.1\% of the storms follow the criterion of Ey >= 2 mV m(-1) for intervals longer than 2 h. It is concluded that southward directed interplanetary magnetic fields within CIRs/HSSs may be the main energy source for long-term averaged geomagnetic activity on Earth. Citation: Echer E., B. T.

ResumoWe study general multifractal properties of tidal gauge and long-wave time series which show a well defined transition between two states, as is the case of sea level when a tsunami arrives. We adopt a method based on discrete wavelets, called wavelet leaders, which has been successfully used in a wide range of applications from image analysis to biomedical signals. First, we analyze an empirical time series of tidal gauge from the tsunami event of 27 February 2010 in Chile. Then, we study a numerical solution of the driven-damped regularized long-wave equation (RLWE) which displays on-off intermittency. Both time series are characterized by a sudden change between two sharply distinct dynamical states. Our analysis suggests a correspondence between the pre- and post-tsunami states (ocean background) and the on state in the RLWE, and also between the tsunami state (disturbed ocean) and the off state in the RLWE. A qualitative similarity in their singularity spectra is observed, and since the RLWE is used to model shallow water dynamics, this result could imply an underlying dynamical similarity.

ResumoWe analyze the multifractal scaling of the modulus of the interplanetary magnetic field near and far upstream of the Earth's bow shock, measured by Cluster and ACE, respectively, from 1 to 3 February 2002. The maximum order of the structure function is carefully estimated for each time series using two different techniques, to ensure the validity of our high-order statistics. The first technique consists of plotting the integrand of the pth order structure function, and the second technique is a quantitative method which relies on the power-law scaling of the extreme events. We compare the scaling exponents computed from the structure functions of magnetic field differences with the predictions obtained by the She-Lévêque model of intermittency in anisotropic magnetohydrodynamic turbulence. Our results show a good agreement between the model and the observations near and far upstream of the Earth's bow shock, rendering support for the modelling of universal scaling laws based on the Kolmogorov phenomenology in the presence of sheet-like dissipative structures.

ResumoThe white light coronagraphs onboard SOHO (LASCO-C2 and -C3) and most recently STEREO (SECCHI -COR1 and -COR2) have detected a myriad of coronal mass ejections (CME). They are a key component of space weather and under certain conditions they can become geo-effective, hence the importance of their kinematic characterization to help predict their effects. However, there is still a lot of debate on how to define the event boundaries for space weather purposes, which in turn makes it difficult to agree on their kinematic properties. That lack of agreement is reflected in both the manual and automated CME catalogs in existence. To contribute to a more objective definition and characterization of white-light coronagraph events, Goussies et al. (2010) introduced recently the concept of "texture of the event". Based on that property, they developed a supervised segmentation algorithm to allow the automatic tracking of dynamic events observed in the coronagraphs field of view, which is called CORonal SEgmentation Technique (CORSET). In this work, we have enhanced the capabilities of the algorithm by adding several new functionalities, namely the automatic computation of different morphological and kinematic parameters. We tested its performance on 57 well-studied limb CME events observed with the LASCO coronagraphs between 1997 and 2001, and compared the parameters obtained with those from three existent CME lists: two of them obtained from an observer-based detection and tracking method (i.e.; two manual catalogs), and the other one based on the automated detection and characterization of the CME events (i.e.; a fully automated catalog). We found that 51 events could be tracked and quantified in agreement with the CME definition. In general terms, the position angle, and the radial and expansion speeds are in agreement with the manual catalogs used for comparison. On the other hand, some discrepancies between CORSET and the automated catalog were found, which can be explained by the different delimitation of the CME angular extent.

ResumoIn the present paper the local-time variations in the disturbance of the geomagnetic-field horizontal component (H) for eight intense geomagnetic storms that occurred during the descending phase of solar cycle 23 have been analyzed. The study was based on the plot of contour lines of the H-depletion intensity in the plane local time versus universal time (LT-UT maps) with the objective of observing how the morphology and evolution of the ring current is mapped into the surface of the Earth in presence of intense geomagnetic storms. The criterion for the selection of the events was a peak Dst below about-200 nT. The values of the horizontal geomagnetic field were obtained from six mid-latitude stations, with 1 min resolution, and the disturbances were computed by a process similar to that for obtaining the Sym-H geomagnetic index. By means of a cubic spline, the results were interpolated to all longitudes with 6 min in LT spacement. The observed contour maps show, as expected, that the region of largest depletion in H are situated around dusk, as a consequence of the formation of a partial ring current, mainly located in the noon-dusk-midnight hemisphere. However, H disturbances are also observed around midnight and, to a less extend, at the noon-dawn sector. In order to detect a prevalent pattern for the behavior of the geomagnetic-disturbance distribution, a statistical analysis was done by means of occurrence histograms, for different levels of the relative intensity of the storm as a function of local time. The relative intensity for each event was defined as a parameter varying between 0 and 1, with 0 (1) corresponding to the maximum (minimum) horizontal field disturbance during that particular event. Although this analysis does not show the temporal evolution of the disturbance, it confirms the above conclusions about its LT distribution. When only the main phases of the storms are considered in the statistics, the basic differences are the dawn peak is lightly shifted towards noon and that the noon-dawn contribution becomes larger. The observed distributions were tentatively associated with the corresponding interplanetary causes of the events. Since among the eight considered storms four are associated to magnetic cloud with a shock interplanetary structure (sMC) and three to sheath regions followed by a magnetic cloud (SH/MC), the statistical study was also performed for the two subsets of storms separately. For the first group (sMC) the LT distribution looks very similar to that of the whole set of storms. On the other hand, it was observed that for the last group (SH/MC) the peak around midnight was not present. This result might be a consequence that these type of storms are probably not associated to the presence of substorms.

ResumoComet 19P/Borrelly plasma waves associated with the ion pickup process are being studied for the first time. The compressive plasma waves (short, large-amplitude, magnetic structures, or SLAMS) have peak-to-background magnetic field magnitude amplitudes as large as ∼91. A new method of analysis has been developed to study the properties these compressive waves (and the bow shock) and is applied in this study. The bow shock at the time of the DS1 crossing was determined to be quasiparallel in nature with θBn∼22°. Using this new technique and minimum variance analyses over single wave cycles, most of the waves were determined to be circularly polarized, but some were noted to have linear and sunglass polarizations. The waves propagated obliquely to the ambient magnetic field B0, with over 75% of the cases with θkB0>45°. The intrinsic wave polarization in the plasma frame was investigated by examining waves propagating obliquely to the solar wind direction, θkx>75°, where x is the solar wind velocity vector. From this analysis, a mix of right-hand (RH) and left-hand (LH) polarization waves were found, with no particular order, either as a function of distance upstream or closeness to the bow shock. Most of the waves were detected when B0 was oblique to Vsw. The equal mix of RH and LH waves is not well explained by current theoretical models. It is possible that the Dubouloz and Scholer (1995) scenario could work for this cometary case if both RH and LH waves were generated by ring-beam distributions.

ResumoWe revisit previous studies in which the characteristics of the solar and interplanetary sources of intense geomagnetic storms have been discussed. In this particular analysis, using the Dst time series, we consider the very intense geomagnetic storms that occurred during Solar Cycle 23 by setting a value of as threshold. After carefully examining the set of available solar and in situ observations from instruments aboard the Solar and Heliospheric Observatory (SOHO) and the Advanced Composition Explorer (ACE), complemented with data from the ground, we have identified and characterized the solar and interplanetary sources of each storm. That is to say, we determine the time, angular width, plane-of-the-sky, lateral expansion, and radial velocities of the source coronal mass ejection (CME), the type and heliographic location of the CME solar source region (including the characteristics of the sunspot groups), and the time duration of the associated flare. After this, we investigate the overall characteristics of the interplanetary (IP) main-phase storm driver, including the time arrival of the shock/disturbance at 1 AU, the type of associated IP structure/ejecta, the origin of a prolonged and enhanced southward component (Bs) of the IP field, and other characteristics related to the energy injected into the magnetosphere during the storm (i.e. the solar wind maximum convected electric field, Ey). The analyzed set consists of 20 events, some of these are complex and present two or more Dst minima that are, in general, due to consecutive solar events. The 20 storms are distributed along Solar Cycle 23 (which is a double-peak cycle) in such a way that 15% occurs during the rising phase of the cycle, 45% during both cycle maxima, and, surprisingly, 40% during the cycle descending phase. This latter set includes half of the superstorms and the only cycle extreme event. 85% of the storms are associated to full halo CMEs and 10% to partial halo events. One of the storms occurred at the time contact with SOHO was lost. The CME solar sources of all analyzed storms, but one, are active regions (ARs). The source of the remaining CME is a bipolar low-field region where a long and curved filament erupts. The ARs where the CMEs originate show, in general, high magnetic complexity; ¦Ä spots are present in 74% of the ARs, 10% are formed by several bipolar sunspot groups, and only 16% present a single bipolar sunspot group. All CMEs are associated to long duration events (LDEs), exceeding 3 h in all cases, with around 75% lasting more than 5 h. The associated flares are, in general, intense events, classified as M or X in soft X-rays; only 3 of them fall in the C class, with the one happening in the bipolar low field region hardly reaching the C level. We calculate the lateral expansion velocity for most of the CMEs. The values found exceed in all cases but one the fast solar wind speed (¡Ö750 km s−1). The average lateral expansion velocity is 2400 km s−1. The spatial distribution of the solar CME sources on the solar disk shows an evident asymmetry; while there are no sources located more eastward than 12¡ã in longitude, there are 7 events more westward than12¡ã. Nevertheless, the bulk of the solar sources are located near Sun center, i.e. at less than 20¡ã in longitude or latitude. Considering the IP structures responsible for a long and enhanced Bs, we find that 35% correspond to magnetic clouds (MCs) or ICME fields, 30% to sheath fields, and 30% to combined sheath and MC or ICME fields. For only one storm the origin of Bs is related to the back compression of an ICME by a high speed stream coming from a coronal hole in the neighborhood of the corresponding CME source region. We have also found that for this particular set of storms the linear relation between Ey and the storm intensity holds (with a correlation coefficient of 0.73). These results complement and extend those of other works in the literature.
