Why is there more rain in rural areas than in cities? How to explain it in meteorology?

When we are in our hometown, we often feel that it rains heavily in our hometown, often for two or three days. It is that kind of rainy weather, not only the clothes are not dry, but also they are often moldy and wet. But when I return to the city, not only will it not rain, but I will also feel very dry, not as humid as when I was in my hometown. So, why is there more rain in the countryside than in the city?

First, the city has a large population. First of all, this is because the city has a large population and the hometown has a small population. Because there are many people working and living in cities, the carbon dioxide content produced by production and life will be more than that in rural areas, and the temperature will be higher than that in rural areas. But the factor of rain must be the collision of hot and cold, which will produce water vapor and then form rain. The temperature in the city tends to be consistent, so it is not easy to produce water vapor, so it is not easy to rain. The temperature in rural areas is prone to a large temperature difference between day and night, which in turn leads to rain.

Second, the terrain reasons Second, the terrain is also a factor affecting precipitation. The topography of the city is relatively flat, which has little influence on the formation of precipitation, while the countryside is generally located in hilly areas, where the topography changes greatly and is rugged. During the day and night, the influence on solar radiation is inconsistent, and it is easy to produce temperature difference, so it is easy to cause water vapor, so there will be more frequent precipitation in rural areas than in cities.

Third, urban pollution is more serious. Finally, there is less precipitation in cities, which is also related to its pollution level. Due to the rapid development of urban economy and wide industrial application, the pollution degree of cities is heavier than that of rural areas. Excessive carbon dioxide emissions have cast a thick veil on the atmosphere, making it impossible for water vapor to condense. There is not so much industrial pollution in rural areas, the air quality is better, the concentration of pollutants in the air is lower, and it is easy to form water vapor. Therefore, when we are in the countryside, although we often encounter rainy season, the air will be better, which is beneficial to our health.
