Generation and distribution of precipitation in the Eastern Mediterranean coastal zone as seen from experiments using cloud ensemble model with detailed description of warm and ice microphysical processes
- Hebrew Univ. of Israel, Jerusalem (Israel). Inst. of Earth Sciences
Precipitation in the Eastern Mediterranean takes place mainly in cold season when westerlies are a dominating wind system. In winter the land is warmer than the sea surface by several degrees. This sea-land temperature difference causes the formation of land breeze-like circulation near the shore line. Space distribution of convective cloudiness and precipitation close to the shore line strongly depends on the interaction between this local thermally induced circulation and background flow. This interaction often leads to the formation of strong low-level convergence over the sea near the coastline about ten to several tens km from the shore as well as to a persistent cloud generation in this convergence zone. In the present study the authors consider the following questions: (a) What factors determine the location of the breeze front and precipitation distribution? Is the location of the front determined by boundary layer circulation only or deep convection influences its location as well? (b) What is the contribution of deep convection forcing to the intensity of coastal circulation during land winter breeze in eastern Mediterranean? (c) What is the contribution of relative air humidity over the land to the precipitation amount?
