چکیده
This study investigated the impact of sea surface temperature (SST) on extreme precipitation events in North Japan and its relation to synoptic weather patterns using large-ensemble climate simulations. Eight were identified by applying cluster analysis level pressure anomalies for selected days with derived from a 3000-year historical experiment. Interannual variability associated two specific patterns, characterized weak low-pressure system an atmospheric river (AR), significantly correlated that SST over Sea Japan, correlation coefficient 0.37 0.53, respectively. In higher years, increased moisture can increase inland area Hokkaido pattern system, whereas it appears enhance orographic along western slopes mountains resembling AR. These results indicate effect local strongly depends patterns. future projection, are sensitive show sharp more than 4 times under K warming climate. Moreover, magnitude was also found SST, broadly following Clausius–Clapeyron both warmed climates. suggest risk heavy such future.

Impact of High Resolution Sst Data on Regional Weather Forecasts
1. INTRODUCTION Past studies have shown that the use of coarse resolution SST products such as from the real-time global (RTG) SST analysis[1] or other coarse resolution once-a-day products do not properly portray the diurnal variability of fluxes of heat and moisture from the ocean that drive the formation of low level clouds and precipitation over the ocean. For example, the use of high resol...
متن کاملA new precipitation and drought climatology based on weather patterns
Weather-pattern, or weather-type, classifications are a valuable tool in many applications as they characterize the broad-scale atmospheric circulation over a given region. This study analyses the aspects of regional UK precipitation and meteorological drought climatology with respect to a new set of objectively defined weather patterns. These new patterns are currently being used by the Met Of...

Rabies in Iran: Past, Present and Future
Introduction : Rabies is a disease that has been known since antiquity. It is a highly fatal acute disease of the central nervous system caused by a lyssavirus. Prior to the discovery of the rabies vaccine, rabies-infected individuals fell victim to the delusions and superstitions associated with this disease. Though it has been neglected in many regions of the world, rabies remains one ...
