Why is the climate in Tianjin so bad? Thank god, help me.

It is windy in spring in Tianjin. There was not so much yellow sand in the past, but now with desertification, it is not only windy, but also sandy. Tianjin is located on the east coast of mid-latitude Eurasia, which is mainly dominated by monsoon circulation. It is an area where East Asian monsoon prevails and belongs to temperate monsoon. Although it is close to Bohai Bay, the semi-closed inner bay has little impact on Tianjin's climate. The main climatic characteristics are: four distinct seasons, windy spring, drought and little rain; Summer is hot and the rain is concentrated; Autumn is cool and the temperature is moderate; Winter is cold, dry and snowy.
