- Abstract
The South American jet stream (SALLJ) and the precipitation occurrence on the Peruvian jungle were analyzed, taking into account data from the Global Forecast System (GFS) atmospheric model and accumulated precipitation data estimated by the Tropical Rainfall Measuring Mission (TRMM) satellite in the southern summers between the years 2005 and 2014. The Weibull distribution was used for the statistical analysis of the southern north wind and the Kendall's non-parametric correlation statistical test to associate the SALLJ events defined by the criteria of Whiteman et al. (1997) and Bonner (1968). The results reveal that the average behavior of the southern component of the wind fluctuates between 1.2 and 11.7 m/s with variations of +/- 3.2 m/s, registering a maximum wind of 21.4 m / s. Of a total of 39 cases, 53.8% were identified with the conditions proposed by Whiteman and 46.2% with the conditions of Bonner. Maximum rainfall of 64.00 mm/day and a greater number of days with rainfall associated with SALLJ events were recorded for 00 UTC.
