The Weather In Israel
Although relatively small, to understand the Israeli weather we need to divide Israel into three different climatic zones:
1. Mediterranean climate
Most of the central and northern part of the Land of Israel is in this area. The Mediterranean climate is characterized by hot and poor summers in precipitation, volatile transition seasons and a rainy (rarely snowy) cold season. In the Mediterranean climates more than 400 mm of precipitation falls annually.
2. Arab climate, semi-arid
It is a kind of climate between the Mediterranean and the desert climate. It is impossible to define exactly where the boundary between the types of climate passes, due to the year-to-year variation in the amount of precipitation in the Arab climate areas. Beersheba, for example, is in this climate zone. In the Arab climates, between 200 and 400 mm of precipitation falls annually.
3. Desert climate
Most of southern Israel is in this area and is part of a global strip of subtropical deserts. It is an arid, low-lying area all year, with no more than 200 mm of precipitation falling per year.
Why is winter precipitation falling in Israel?
Cloudiness that brings with it precipitation is caused by the presence of barometric outlets. Barometric socket backed by atmospheric wave above it – bromine. It passes through the Mediterranean in the winter and is called the Rom Bus. In winter and part of spring and autumn it is located along the Mediterranean, causing precipitation to occur at its whereabouts. Its shape is the shape of a bowl or the letter of the letter U. In the summer the Roman channel is not because the subtropical level dominates the Mediterranean and blocks its arrival.
In winter, snow sometimes rains in the high mountains of Israel. Snow is most common in mountains over 700 meters, but snow 500 meters is not that rare. On February 6, 1950, snow fell even at sea level in the coastal plain, Tel Aviv and other coastal cities. The conditions required for snowfall in Israel are a Cypriot sediment that allows precipitation whose wind trajectory it does not go too far over the sea. (The temperature of the sea is relatively warm and it heats the air in the lower layers.)
Frequently during a Siberian level, temperatures in many places in Israel (especially in the valleys and high mountains) fall below zero. Siberian levels are at their peak in December, so solar radiation is the weakest of the year. Under the influence of a Siberian plateau, the sky is clear and the north-east wind direction. The result is dry, cold air infiltration from Russia and the Black Sea to Israel.
