Abstract ERA5 reanalyses and observations of convective clouds precipitation are used over the northern Gulf Guinea between 7°W 3°E to study influence ocean surface temperature land–sea gradient on Coast rainfall (GCR) in boreal spring summer. Seasonal composites calculated around two dates indexing onset ( T ref ) demise end GCR. The date corresponds emergence equatorial upwelling spring, whic...

There is still no consensus on the mechanisms that modify precipitation over and around cities, especially for those located in tropics where convective processes primarily drive rainfall. Here we contribute to ongoing discussion about urban-associated by investigating urban effect diurnal cycle of rainfall Singapore. We use version numerical weather prediction system Meteorological Service Sin...

In this work the higher flood events occurred in Brazil from 1979 to 2010 were determined in order to describe the atmospheric circulation patterns associated with them. An analysis was hold in the 23 extreme ones, according to the season (summer/winter) and the region where the event occurred. The main causes identified were the El Nino episodes, Madden-Julian Oscillation, ITCZ and SACZ, besid...

The diurnal and seasonal variations of the northern Australian dryline are examined by constructing climatologies of low-level dynamic and thermodynamic variables taken from the high-resolution Australian Bureau of Meteorology’s Limited Area Prediction Scheme (LAPS) forecasts from 2000 to 2003. The development of the dryline is analyzed within the framework of the frontogenesis function applied...

Abstract The Weather Research and Forecast (WRF) model is used to simulate atmospheric circulation during the summer season in a coastal region of central Italy, including city Rome. time series surface air temperature, wind speed, direction are compared with situ observations urban Rome its rural surroundings. Moreover, vertical profiles sodar measurements. To improve WRF model’s ability repro...

The sea-land breeze (SLB) occurs regularly in coastal areas and influences the local climate atmospheric environment. Fifteen-year observations (2005–2019) from urban, coastal, marine stations were collected to examine trend number of SLB days (SLBD) Tianjin, a megacity China. SLBD Tianjin generally showed decreasing with an annual average decline rate 3.89%. land speed decreased by 0.20 m·s−1 ...
