How hot is it in Henan in summer?

1, Geographical location and climate: Henan is located in the middle of China, in the transition zone from subtropical zone to warm temperate zone, and is also influenced by the East Asian monsoon. In summer, the warm and humid monsoon blows from the south, bringing a lot of hot and humid air, which causes the temperature to rise. Henan is located inland, affected by the thermal effect of the land, lacking the regulating function of the ocean, and the heat is more obvious in summer.

2. High temperature heat island effect: Summer is the season of high temperature in Henan, and the temperature is often above 30 degrees Celsius, sometimes even over 40 degrees Celsius. Most areas in Henan are relatively flat, and the land cover is mainly cultivated land, which will lead to the heat island effect in the city and its surrounding areas. Heat island effect refers to the phenomenon that the temperature difference between inside and outside the city increases, and the heat released by a large number of buildings, concrete and human activities in the city gathers in the urban area, which leads to the increase of the temperature of farmland and rural areas around the city.
