Study of the convergence of low cloudiness by the effect of ocean breeze using the regional climate model

This work sought to analyze in high resolution the downscaling of global model Climate Forecast System Version 2 (CFSv2) by using regional climate RegCM-4.9. The precipitation fields were generated two different domains and spatial with 10 km 3 km, for August October 2020. equatorial region Northeast Brazil can be characterized complex dynamics that encompass atmospheric movements such as existence convergence at low levels convective cloudiness its diurnal effect on cloud cover influence evident precipitation. However, meteorological scales a daytime circle, land-ocean breeze Gulf Maranhão this theoretical night shows peak between 6 9 am local time. seeks recognize Alcântara cycle, aerospace activities increasing and, depending intensity, generating more intense rainfall coastal even dry period, which corresponds most suitable period operational Launch Center.
