(A weather phenomenon)

Winter comes to spring, and it is still cold at first, when people get up, they find that the world outside the window has fallen into a mist.

From a meteorological point of view, after a long period of low temperature, the surface of the object is completely cold. When the temperature of the object is less than or equal to the dew point temperature, the water vapor in the air is saturated and starts to condense on the surface of the object. , Water droplets, the phenomenon of returning to Nantian. The so-called dew point temperature refers to the temperature when the air temperature is reduced to saturation when the water vapor content and air pressure in the air are unchanged. The main reason is that after the cold air passes, the warm and humid airflow quickly counterattacks, causing the temperature to rise and the air humidity to increase. Some cold objects are prone to produce water droplets when they encounter the warm and humid airflow. ^[1]

People with these diseases need to keep warm. Patients with chronic diseases such as hypertension should take medications and monitor blood pressure on time, and pay attention to preventing the occurrence of diseases such as stroke.
