What's the climate like in Tangshan all year round?

Tangshan city belongs to the continental climate zone of warm temperate zone and semi-humid monsoon type. Winter is controlled by polar continental air mass, with cold climate and scarce rain and snow; In spring, due to the influence of continental air mass, there is not much precipitation, and because of the prevailing northerly or westerly winds, the evaporation increases, often forming dry weather; In summer, due to the northward shift of the Pacific subtropical high ridge, the warm and humid air flow from the southwest or southeast ocean surface is transported northward, which becomes the main precipitation season; In autumn, the southeast monsoon weakens, the polar continental air mass gradually strengthens, and autumn gradually turns into a crisp rainy season.
