Lebanon is found in the Middle East, at the coordinates 33˚N and 35˚E. Lebanon is a narrow and long country. It has a long coastline bordering the Mediterranean on its Eastern side. It has an alternating geography of 4 parallel areas that run North to South. Furthest west, there is the coastal lowland, that then rises to the Lebanon Mountains. Continuing Eastward the mountains descend into the Biqa Valley. Furthest West there is a narrow strip of mountain range, called the Anti-Lebanon Mountains. The alternating topography has an effect on the weather in Lebanon, although the overall climate is Mediterranean.

Generally speaking the summers are hot and dry while winters are cooler and rainy. While spring and autumn

The lowlands along the coasts have a smaller temperature range between the seasons. In the Lebanon Mountains the winters are colder because of the higher elevation and there is more precipitation which sometimes falls as snow. The summers may get as warm as the costal lowlands during the day, but during the night temperatures drop much lower. The Biqa Valley has less precipitation and temperatures vary more both daily and yearly, because of the Lebanon Mountains that acts as a shield from the effects caused by the sea. The Anti-Lebanon Mountains have more precipitation often in the form of snow, because of the altitude, than the Biqa Valley. Temperatures are lower as well here and the ranges are …show more content…
The areas that are mountainous have more precipitation than the lowland areas. This can be explained as this precipitation is orographic. Orographic precipitation is formed when warm moist air, from the ocean for example, is moving and forced to rise because of a mountain. As the air rises it cools down, when air cools down it cannot contain the same amount of moisture, so the moisture condenses and falls in the form of snow or rain. In Lebanon the warm moist air from the Mediterranean sea rises and cools above the Lebanon mountains causing there to be more precipitation there. On the other side of the mountains the moisture is lost so the Biqa Valley receives less precipitation. The air falls, heating up and picking up moisture from two of the rivers in the valley. When it reaches the foot of the Anti-Lebanon Mountains it is forced to rise, causing it to cool, condense and then rain or snow. This explains why the two mountain ranges have more precipitation than the two lowlands

During the summer months the ocean carries currents that bring dry air, while during the winter months the ocean carries currents that bring warmer moister air. The dry air makes it hard for clouds to be formed, while the moister air easily forms to clouds. This can partly help explain why there is a wet season during the winter, and a dry season during the
