How to judge windward slope or leeward slope according to the picture

Due to the influence of topography on climate, windward slopes and leeward slopes in mountainous areas often form different natural environments.

1. The windward slope cools down because the terrain blocks the warm and humid airflow, and it is easy to cloud and cause rain, with more precipitation. The leeward slope is popular in downward flow, but it is difficult to cloud and cause rain, with less precipitation.

2. There are differences in precipitation at different altitudes on the windward slope. There is less precipitation in the foothills and the top of the mountain, and the air humidity at the top of the mountain has been greatly reduced, with less clouds and rain, and the most precipitation in the middle of the mountain.

3. The diurnal temperature range of windward slope and annual range are smaller than that of leeward slope. In cloudy and rainy weather on the windward slope, the atmosphere has a strong weakening effect on solar radiation, and the temperature will not be too high. At night, the atmosphere has a strong insulation effect on the ground, and the temperature will not be excessively reduced. On the leeward slope, it is the opposite.

4. If the mountain uplifts the airflow excessively, the windward slope and the leeward slope even present completely different natural landscapes. The altitude of the natural belt broken by the wind is higher than that of the leeward slope, because the wind breaks through the rain and the heat is sufficient.

5. The distribution of snow lines on windward slopes is lower than that on leeward slopes.

6. The windward slope has superior natural conditions and is more suitable for the distribution of population and towns, so the distribution of population and towns is denser and the economy is more developed. The leeward slope is the opposite.

Extended data

The windward slope is the one where the wind blows up along the slope. Due to the influence of topography on climate, windward slopes and leeward slopes in mountainous areas often form different natural environments, which in turn form different human environments.

Leeward slope refers to the side that forms the terrain in the middle of orographic precipitation and has less precipitation. Because this side is just on the back of the warm and humid airflow blocked by the terrain; There are few vegetation and animal and plant resources on the leeward slope. Light and heat are also less obtained, and the leeward slope area is cold. People's living distribution, architecture and other cultural landscapes are also sparse.

the main feature of windward slope is that the wind blows upward along the slope.

The formation of leeward slope is that the terrain blocks warm and humid airflow and concentrates water vapor on windward slope. When the water vapor gathers and reaches a certain intensity, it will form precipitation on windward slope.
