RELAÇÃO ENTRE A PRECIPITAÇÃO PLUVIOMÉTRICA NO SEMIÁRIDO DO ESTADO DO RIO GRANDE DO NORTE E A TEMPERATURA DA SUPERFÍCIE DO MAR DO ATLÂNTICO TROPICAL

Abstract

The purpose of this work was to evaluate projections of Sea Surface Temperature (SST) over the Tropical Atlantic Ocean and precipitation over the semiarid, as well as the relationship between these two variables for the historical and RCP 6.0 experiments of the AR5/IPCC for the years 2006 to 2017 of the models. Thus, it was necessary to infer how the projections of these experiments can be used as tools for analyzing the future state of the SST over the tropical Atlantic and on the precipitation in the semiarid region of RN. RStudio and Microsoft Excel 2017 were used for statistical analysis of precipitation, calculating the standard deviation of precipitation data, analyzing the precipitation over the SST of the North and South Tropical Atlantic and the rainfall anomalies of the historical model and the experiment CPR 6.0. Taking into account the results obtained, it was observed that in the months when the SST over the southern tropical Atlantic is warmer and less heated in the northern portion of the tropical Atlantic ocean, it is possible to notice an increase in the recorded precipitation averages, thus, when The TSM region of the South Atlantic is warmer, the surface pressure decreases, thus, there is greater evaporation of the water content of the ocean and corroborates the intensification of upward movements that intensify the mass convergence, favoring the formation of clouds and precipitation. Therefore, the results obtained indicate that both experiments overestimate the precipitation in the semiarid region of RN.
