| Abstract | The Center for Weather Forecast and Climatic Studies (CPTEC/INPE) developed a set of Cloud Drift Winds (CDW) models using GOES satellites images. These models use the visible (0,5ìm), near infrared (3,9ìm), water vapor (WV - 6,7ìm) and infrared (IR-10,2ìm) channels. Visible and near infrared CDW models are used to estimate winds in lower atmospheric levels while the IR and WV models are used to estimate wind in the middle and high levels. From 1st March 2007 GOES-10, located in 60W, began to be the INPE/CPTEC operational geo satellite. Using GOES-10 INPE/CPTEC began to produce operationally cloud drift wind, each 15 minutes, for the four channels described above. This higher time resolution makes possible to identify displacement of clouds more precisely raising the results quality. Beyond the aspect of the temporal resolution, GOES-10 is exclusively dedicated to South America allowed to get regularly wind fields. GOES-10 CDWs models have a new automatic quality control based on the methodology used by the EUMETSAT. Each vector is evaluated, in different aspects, for a series of equations and its results are combined in a quality indicator (QI). This index makes possible that the final user choose a threshold in accordance with its needs. This study presents the quality evaluation using GOES-10 and the new quality indicator function. Using WV Atmospheric Motion Vectors (AMV) we have computed the upper levels wind divergence. The AMV's estimated by using water vapor images are interpolated in a regular grid. From this filed is calculated wind divergence above of 400hPa using finite differences methodology. This study uses a 0.5 degrees spatial resolution grid each 15 minutes. The preliminary results evidence the great potential of these fields for operational applications. This paper describes the current operationally CDW operationally running in INPE/CPTEC, the wind vectors quality and some examples of the wind divergence applications. |
