Causes of low temperature and lack of rain in North African ports in summer

The ports in North Africa belong to the Mediterranean climate. The low temperature in summer is related to the thermal difference between land and sea in the Mediterranean, and the low precipitation is related to the control of the subtropical high zone.

Take Alexandria as an example, the average temperature in summer is 26℃, and the total precipitation in three months in summer is less than 100 mm ... The reasons for this climate feature are:

(1) The latitude of Alexandria is about 3 1 N, which is relatively high, and it is impossible to form the high temperature like the low-latitude tropics.

(2) In summer, controlled by the subtropical high, the airflow sinks, with less precipitation and more sunny days, which is easy to form high temperature. The port is located on the Mediterranean coast. Due to the temperature difference between land and sea, the temperature in the Mediterranean is lower than that in the mainland, and the temperature along the Mediterranean coast will not be very high.

Other ports in North Africa have low temperature and less precipitation in summer, which is similar to Alexandria.
