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 the Weather Research and Forecasting (WRF) – Advanced Research WRF (ARW) mesoscale model (WRF–ARW), we investigate how two nocturnal offshore rainbands occurring in the Mediterranean basin are modified in a warmer sea surface temperature (SST). After sunset, the thermal difference between land and sea air increases. Driven by drainage winds or land breeze, the inland cold air interacts wi...

The paper contains a preliminary study of the sea breeze at Thumba (08°32' N, 76° 52'E) based on observations 392 days, spread over period three years (1963-1966).
 
 Analysis hourly wind observation reveals that northeasterly or northerly land is replaced by westerly southwesterly before mid-day during October to May it also seen November April are favoured most Thumba. Southerly set...
