Does it snow in Shanghai every year?

It doesn't snow in Shanghai every year.

Shanghai is located in the subtropical maritime climate, and its geographical position is relatively south, so it doesn't snow in Shanghai every year. At the same time, even if it does snow, it is mainly snow species, and there is little heavy snow.

According to statistics, the snowfall in Shanghai is mainly cold current snowfall, also known as ocean effect snowfall. It means that when strong cold air passes through warm water, the water vapor evaporated on the sea surface suddenly condenses into snowflakes, forming snowfall. Shanghai's geographical location and topography are unfavorable, and this kind of snowfall generally has the characteristics of small distribution range, short duration and weak snowfall intensity.

At the same time, due to the heat island effect in Shanghai, the average temperature in winter is above zero, which is not enough to solidify into snow.

At the same time, Shanghai is located in the low latitude area, far away from the cold air mass in the high-dimensional area, and China's multi-east-west mountains can effectively block the cold air from the cold air mass in the high latitude area from going south.

It is precisely because there are few days of snowfall in Shanghai and the intensity is generally weak, so Shanghainese have a particularly excited mood about snow. Once it snows, the circle of friends is bound to be carnival, even if it is just a few small snowflakes, it is enough to make people happy and excited.
