The time dependent reactions of an isothermal spherically symmetric stellar atmosphere to perturbations of the external (interstellar) pressure are analysed by means of computer simulations. The system is seen to evolve, through the phases of wind, breeze, accretion and back, according to an hysteresis type cycle with two catastrophe points: the value of the external pressure relative to a stat...

Using a high-resolution regional climate model RegCM3, station and satellite observations, we have studied the spatial heterogeneity of climate variability over Java Island, Indonesia. Besides the well-known anomalous dry conditions that characterize the dry and transition seasons during an El Niño year, analysis of regional model output reveals a wet mountainous south versus dry northern plain...

Abstract. Deep convection plays important roles in producing severe weather and regulating the large-scale circulation. However, deep-convection initiation (DCI), which determines when where deep develops, has not yet been fully understood. Here, large-eddy simulations are performed to investigate detailed processes of DCI, occurs through collision two sea-breeze fronts developing over a penins...

Sea breezes are important in a coastal urban climate; however, the impact of development on effects sea breezes, which decrease air temperature and increase humidity, has not been understood quantitatively. To quantitatively evaluate this Sendai, Japan over past twenty years, study analyzed heat balance mechanisms spaces based simulation results Weather Research Forecasting (WRF) model coupled ...

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...
