Who knows what the weather is like in North Africa?

Hello: North Africa generally refers to Egypt, Algeria, Libya, Western Sahara and Tunisia. The south of North Africa is located in the Sahara desert, with a tropical desert climate. North Africa is close to the Mediterranean Sea and belongs to the Mediterranean climate.

Climate characteristics: hot and dry in summer, high temperature and little rain, mild and rainy in winter.

The temperature is 5℃ ~ 10℃ in winter and 2 1℃ ~ 27℃ in summer. The annual precipitation is about 350 mm ~ 900 mm, concentrated in winter. The precipitation in the second half of the year only accounts for 20% ~ 40% of the annual precipitation, and the maximum monthly precipitation is more than twice the minimum monthly precipitation. [Edit this paragraph] The reason is that in summer, the wind belt of the pressure belt moves northward, and under the control of the subtropical high, the airflow sinks, resulting in drought and little rain. In winter, the wind belt of the pressure belt moves south, and is influenced by the prevailing westerly wind from the ocean, with abundant precipitation and mild and humid climate. [Edit this paragraph] The distribution law is distributed on the west coast of the mainland between 30 and 40 north latitude. It is also widely distributed, and it is the only climate type that exists in all continents except Antarctica. [Edit this paragraph] Specific distribution areas There are five regions in the world with this climate:

(1) the Mediterranean coast, including southern Europe, the northern coast of Africa and a few areas in western Asia.

(2) the California coast of North America.

(3) the west coast of southern Africa, that is, western South Africa and southern Namibia (called the Cape of Good Hope region or the Cape of Good Hope region).

(4) Central Chile in South America.

(5) the southwest and southeast coasts of Australia (although it is southeast, it belongs to the west coast, near Adelaide, not Sydney). [Edit this paragraph] Typical vegetation subtropical evergreen broad-leaved forest. There are also dry shrubs or hard-leaved grasslands (Stipa, etc.). ).

The Mediterranean climate is characterized by westerlies in winter, frequent frontal cyclones, mild climate, the lowest monthly average temperature of 4 ~ 10℃ and abundant precipitation. Summer is controlled by subtropical high, the airflow sinks, the climate is hot and dry, the clouds are sparse, and the sunshine is sufficient. The annual precipitation is 300 ~ 1000mm, accounting for 60% ~ 70% in winter and only 30% ~ 40% in summer. The climate characteristics of rainy winter and dry summer are unique among various climate types in the world.

2. Typical climatic reasons

The Mediterranean climate is mainly caused by the westerlies in winter, with frequent frontal cyclones. In summer, controlled by the subtropical high pressure belt, the airflow sinks. Among more than ten climate types in the world, the climate types controlled alternately by pressure belts and wind belts throughout the year include tropical grassland climate (controlled alternately by equatorial low pressure belts and trade winds) and tropical desert climate (controlled alternately by trade winds and subtropical high pressure belts) in addition to the Mediterranean climate. The climate controlled by westerlies throughout the year is temperate maritime climate. From the analysis, it can be seen that the investigation of the causes of Mediterranean climate not only examines the students' mastery of the distribution of subtropical high (the maximum influence latitude is 20-40 degrees north and south latitude) and westerly belt (the maximum influence latitude is 30-60 degrees north and south latitude), but also examines the movement of pressure belt and wind belt. It can be said that if students can accurately understand the causes of the Mediterranean climate, it should be easy to understand other climates.

3. Widespread climate distribution

The Mediterranean climate distribution law is located on the west coast of the mainland between 30-40 degrees north and south latitude. Mediterranean climate is the only climate type that exists on all continents except Antarctica. Among the distribution areas of Mediterranean climate, the Mediterranean coast is the most obvious. Other areas such as the California coast in North America, central Chile in South America, the Cape of Good Hope at the southern tip of Africa and the southwest coast of Australia. Most of its distribution areas are economically developed and are also hot spots in the world.
