Briefly describe the distribution patterns of temperature and precipitation and what are the influencing factors

1. Distribution rules

1. The development of the weather system, the intersection of warm and moist air and cold air, causing the warm and moist air to be forced to rise by the cold air, or the warm and moist air Climb along the frontal slope.

2. Local thermal convection in summer causes warm and humid air to rise with strong convection to form small cumulonimbus clouds and thundershowers.

3. The undulations of the terrain force the windward slope to rise, but this is a relatively minor factor. In most cases, it is combined with the first two processes to influence the geographical distribution of precipitation.

2. Factors affecting precipitation

1. Location of land and sea.

2. Terrain.

3. Atmospheric circulation.

1. Causes of rainfall

During the process of rising, water vapor gradually becomes Tiny water droplets or ice crystals float in the air to form clouds. Precipitation occurs when cloud droplets grow large enough to overcome the resistance of the air and the support of updrafts, and are not evaporated when they fall.

The condensation of water vapor molecules on the surface of cloud droplets, and the merging of large and small cloud droplets in constant motion, cause the cloud droplets to continuously condense (or sublimate) and increase in size. Cloud droplets grow into raindrops, snowflakes or other precipitation, and finally fall to the ground. Artificial rainfall is based on the principle of precipitation formation. Artificially spreading catalysts into the clouds causes cloud droplets to rapidly condense, merge and grow to form precipitation.

2. Distribution

Rainy areas throughout the year - areas near the equator, with a lot of precipitation, such as Singapore

Rainy areas throughout the year - arid desert areas, Polar regions, such as Cairo

Rainy areas in summer - the east coast of the continent near 30° to 40° south and north latitudes, rainy areas in summer, such as Beijing

Rainy areas in winter - south and north latitudes The west coast of the continent near 30° to 40° north latitude is rainy in winter, such as Rome

The perennially humid area - the west coast of the continent near 40° to 60° north latitude is wet all year round, such as London
