What season is the northwest wind?

Northwest wind blows in autumn and winter. Northwest wind refers to the wind blowing from the northwest, which can also be considered as west wind or north wind. According to the definition in meteorology, northwest wind refers to the wind blowing from the northwest.

The temperature on the sea and land in our country is different. In winter, the temperature of the ocean is higher than that of the land. The air flow is always in the direction from cold air to hot air. So the winter wind always blows from the land to the southeast sea, which is why the northwest wind always blows in winter.

The autumn equinox is windy in the northwest, and the twelfth month is unclean in winter.

If the northwest wind blows at the autumnal equinox, there will definitely be a lot of snowfall throughout the winter. With more snowfall, there will naturally be a lot of snow on the ground, which will inevitably lead to muddy roads, so it will become unclean in winter.

After the autumnal equinox solar terms, the temperature will be affected by the cold air from Siberia, which is located in the northwest of China, so we often call the cold air from Siberia the northwest wind. According to the older generation, the northwest wind blows at the autumnal equinox, indicating that the cold air is very active this year, and there may be rainy weather under the influence of cold air.
