             abstract = "Severe meteorological events usually interfere both with natural 
                         and human systems, thus causing the most diverse problems and, 
                         even, disasters. Among these events, e.g., the rains above 100 
                         mm/day may cause floods and the collapse of hill sides in urban 
                         areas.The sudden and strong decrease of the temperature, besides 
                         the well known agricultural and cattle raising effects, may induce 
                         the fall of the tree leaves in the non-deciduous Terra Firme 
                         Amazon forest; also, it may cause acute pulmonary sicknesses in 
                         less resistant persons. The cloudiness may affect the development 
                         of the plants. On the other hand, the persistence during several 
                         days of stagnations of warm and dry air masses increases the air 
                         pollution and the fire risks, while it also decreases the 
                         atmospheric visibility. Thus, the knowledge of these phenomena, as 
                         well as their predictability, is of utmost importance for a 
                         region. Thus, this work presents the severe rain, low temperature 
                         and high cloudiness events measured through an automatic weather 
                         station (AWS) located at the Fazenda Caiabi (9 deg 58 min S; 56 
                         degr 21 min W), Alta Floresta, Mato Grosso, Brazilian Amazon. 
                         Also, during the period between May 30, 1999 and September 15, 
                         2003, the stagnation of warm and dry air masses periods were also 
                         determined. Further, after August 2002, CPTECs ETA Regional 40 x 
                         40 km numerical weather prediction model outputs were recorded for 
                         the site, and compared with the values actually measured using the 
                         AWS. The monthly averages for the period mentioned are analyzed. 
                         In addition, the monthly rain climatology for the period 1976 
                         2003, that is, since the opening of the Fazenda trhrough the 
                         slashing and burning of the forest, was obtained from daily 
                         measurements over the whole period. Summarizing for the AWS 
                         period, the lowest daily minimum temperature measured was 7.9 C, 
                         followed by 11.2 C; all other values were above 12 C. The highest 
                         rainfall recorded was 192.5 mm/day, followed by 125.0 and 103.6 
                         mm/day; there were 22 values in the 50 to 100 mm/day range, while 
                         all others fell below 50 mm/day. Concerning the cloudiness, 110 
                         days presented an accumulated daily incident solar energy flux 
                         below 12 MJ/m2 (very cloudy); the minimum was 1.92 MJ/m2, and 
                         there were 16 values below 5 MJ/m2.",
