What type of climate does Hollywood have?

Hollywood, the famous film production base in the United States, has ample light and a suitable climate, making it a natural place for filming movies. Hollywood has attracted a large number of film professionals with its favorable geographical conditions of mild and pleasant climate, abundant sunshine, mountains and rivers, grasslands and sand dunes. Climate: Mild and pleasant all year round.

Hollywood has a Mediterranean climate: a subtropical and temperate climate type. It is named after the most typical Mediterranean coastal area. The most typical reason why the Mediterranean climate is distributed along the Mediterranean coast is that the Mediterranean climate is formed by the alternating control of the westerly belt and the subtropical high pressure belt. In the Mediterranean area, the summer is controlled by the subtropical high pressure belt. The water temperature in the Mediterranean is lower than that of the land, resulting in the formation of high pressure. , increasing the influence of the subtropical high pressure zone, and the water temperature in the Mediterranean is relatively high in winter, forming low pressure, attracting westerly winds, and greatly strengthening the power of westerly winds.

Characteristics:

The summer is hot and dry, with high temperature and little rain, and the winter is mild and rainy. The temperature is 5℃～10℃ in winter and 21℃～27℃ in summer. The annual precipitation is about 350 mm to 900 mm, concentrated in winter. The precipitation in the second half of the year only accounts for 20% to 40% of the annual precipitation. The maximum monthly precipitation is more than twice the minimum monthly precipitation.

Cause:

In summer, the pressure and wind belts move northward. Under the control of the subtropical high pressure, the airflow sinks, causing drought and little rain. In winter, the pressure and wind belts move southward, influenced by the prevailing westerly winds from the ocean, resulting in abundant precipitation and a mild and humid climate.

Features:

1. The particularity of climate characteristics

The characteristics of the Mediterranean climate are: controlled by the westerly wind belt in winter, frontal cyclone activity is frequent, the climate is mild, the coldest monthly average temperature is between 4 and 10°C, and the precipitation is abundant. In summer, under the control of subtropical high pressure, the airflow sinks, resulting in a hot and dry climate with few clouds and abundant sunshine. The annual precipitation is 300-1000 mm, accounting for about 60%-70% in the winter half of the year and only 30%-40% in the summer half of the year. The climate characteristics of winter rain and summer dryness are unique among various climate types in the world.

2. Typical climate causes

The main causes of the Mediterranean climate are that it is controlled by the westerly wind belt in winter and has frequent frontal cyclone activity; in summer it is controlled by the subtropical high pressure belt and the air flow sinks. Among the more than ten climate types in the world, among the climate types that are alternately controlled by air pressure belts and wind belts throughout the year, in addition to the Mediterranean climate, there are savanna climates (equatorial low pressure belts and trade wind belts are alternately controlled) and tropical desert climates (information Wind belts and subtropical high pressure belts are alternately controlled). The climate controlled by the westerly winds throughout the year is a temperate maritime climate. The analysis shows that the examination of the causes of the Mediterranean climate not only examines students' understanding of the distribution of the subtropical high pressure belt (the maximum latitude range is 20-40 degrees north and south latitude) and the westerly belt (the maximum latitude range is 30-60 degrees north and south latitude) After grasping the situation, we also examined the movement of air pressure belts and wind belts. 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. Extensive climate distribution

The distribution pattern of Mediterranean climate is located on the west coast of the continent between 30 and 40 degrees north and south latitude. Mediterranean climate is the only climate type that is found on every continent in the world except Antarctica. Among the areas with a Mediterranean climate, the Mediterranean coast is the most obvious. Other areas include the California coast in North America, central Chile in South America, the Cape of Good Hope region at the southern tip of Africa, and the southwestern coast of Australia. Most of its distribution areas have relatively developed economies and are also hot spots in the world.
