Description
Summary:An observational analysis was conducted in five different cities in Eastern Amazonia, in order to detect the breeze circulations in the region. The frequency of wind direction, wind speed, and precipitation was analyzed along with estimated spatio‐temporal rainfall through the Climate Prediction Center Morphing Technique (CMORPH). The results show different types of breezes that occur in these cities, with regular time from 0900–2100 UTC for SB (sea breeze), 0000–0900 UTC for LB (land breeze), and 1200–0000 UTC for RB (river breeze). The SB has been shown to be more frequent from September to November (SON), while the LB is more prominent from March to May (MAM). However, the RB highlights throughout the whole year in Belém. The hour of occurrence of the SB circulation and the precipitation along the coast has shown a relationship.
