Experimental and modelling results of the dynamics of a sea-breeze event and its effects on the three-dimensional (3-D) redistribution of the gaseous SO 2 are presented within the framework of a particularly flat and industrialized coastal area of the North Sea. The measurements were carried out at ground level with the stations of the local 5 air quality monitoring agency and with two optical ...

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...

Abstract: A set of idealized cloud-permitting simulations is performed to explore the influence of small islands on precipitating convection as a function of large-scale wind speed. The islands are situated in a long, narrow ocean domain that is in radiative-convective equilibrium (RCE) as a whole, constraining the domain-average precipitation. The island occupies a small part of the domain, so...

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...

本稿では，岩石や水の重要な物性である比熱について，簡易に測定可能な実験方法を開発し，試行実践を行った。その結果，水については，理論値よりも過大評価される傾向があったが，岩石については，ほぼ妥当な値を得ることができた。海陸風や季節風の成因を理解するためには，岩石と水の比熱が大きく異なることを理解することが非常に重要である。本稿の方法では具体的に水と岩石の比熱を得ることができ，岩石と水では4倍前後の比熱の違いがあることを理解するために十分な結果が得られた。

Near the vicinity of 308 latitude, the coincidence of the period of sea breeze and the inertial period of the ocean leads to a maximum near-inertial ocean response to sea breeze. This produces a propagating inertial internal (Poincare) wave response that transfers energy laterally away from the coast and provides significant vertical mixing. In this paper, the latitudinal dependence of this wav...

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...
