Weather in Africa 65438+1October

(1) Reading the map, it can be judged as 1 month according to the fact that the northern hemisphere continent is the center of high pressure (or the equatorial low-pressure belt moves southward, or according to the wind direction such as the northerly wind blowing in East Asia).

(2) Reading the map, at this time Iceland is controlled by low pressure (cyclone); In June+10, 5438, the northern Indian Ocean was affected by the northeast wind, and the ocean current flowed counterclockwise. London has a temperate maritime climate, which is mild and rainy all year round.

(3) In the winter of 65438+10, the wildlife in the tropical grassland climate zone in northern Africa moved southward on a large scale, because it was summer in the southern hemisphere at that time, and the tropical grassland climate zone entered summer, and the plants flourished.

(4) East Asian monsoon is caused by the difference of thermal properties between land and sea. The monsoon climate with the same rain and heat provides good conditions for crop growth. At the same time, due to the influence of monsoon climate, droughts and floods are frequent (unfavorable).

So the answer is:

(1) 1 month; There is a high pressure on the northern hemisphere continent (or the equatorial low pressure belt moves south, or judging from the wind direction, such as the northerly wind blowing in East Asia)

(2) Low pressure (cyclone); Inverse; Mild and rainy (rainy)

(3) South; In this season, the southern hemisphere is exposed to direct sunlight, and the equatorial low-pressure zone (trade wind zone) also moves southward, bringing abundant precipitation, promoting plant growth and attracting animals to move southward (or the tropical grassland climate in the southern hemisphere enters the rainy season and plants flourish).

(4) Affected by the difference of thermal properties between land and sea, the pressure center of land and sea changes seasonally, and the prevailing wind direction changes seasonally, forming a typical monsoon climate.

Beneficial effects: the monsoon climate is broad and diverse, which provides convenient conditions for diversified management of agricultural production; Affected by the summer monsoon, it is hot and rainy in summer, and the hydrothermal conditions are good, which is conducive to crop growth.

Adverse effects: affected by the morning and evening monsoon and its intensity, the rainfall variability is large, which is prone to droughts and floods; (For example, in winter, is it cold? Dry, frequent cold waves, easy to form freezing damage to agricultural production. )
