Vertical profiles of aerosol chemical composition, number concentration and size were measured throughout the lower troposphere of Borneo, a large tropical island in the western Pacific Ocean. Aerosol composition, size and number concentration measurements (using an Aerodyne Aerosol Mass Spectrometer, Passive Cavity Aerosol Spectrometer Probe and Condensation Particle Counter, respectively) wer...

Abstract Titan’s northern high latitudes host many large hydrocarbon lakes. Like water lakes on Earth, are constantly subject to evaporation. This process strongly affects the atmospheric methane abundance, temperature, lake mixed layer and local wind circulation. In this work we use a 2D mesoscale model coupled slab investigate effect of solar infrared radiation exchange energy between atmosph...

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 ...

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...

The approach of this study was to determine, theoretically, what impact current and future urban land use in the coastal city of Houston, Texas has on the space and time evolution of precipitation on a `typical' summer day. Regional model simulations of a case study for 25 July 2001 were applied to investigate possible effects of urban land cover on precipitation development. Simulations in whi...
