It is expected that the temperature in Jiangnan, South China and other places will be relatively high in July, and the number of days of high temperature (≥35℃) will be higher than that of the same period of normal years. There will be staged high temperature heat waves. It is necessary to pay attention to the adverse effects of high temperature on human health and make emergency preparations for heatstroke prevention and cooling. .
