Why does the atmospheric inverse radiation increase when sandstorms occur?

Sandstorm belongs to a special weather state when a cold front passes by. The sky is usually cloudy. During the sandstorm, the dust and stones all over the sky prevented the ground from fully absorbing solar radiation, and at the same time reflected and absorbed more solar radiation. A lot of solar energy is stored in the atmosphere and dust in the air. When the solar energy decreases at night, the temperature of the earth drops. At this time, the dust in the air will release the energy absorbed during the day, transfer heat and begin to compensate the ground. Better thermal insulation effect is formed on the ground, that is, the atmospheric inverse radiation is strengthened (it is conceivable that the sky is overcast during sandstorm, just like thickening the quilt on the body, the thermal insulation effect is better, that is, the atmospheric inverse radiation is strengthened). If there are other high school geography problems, we can discuss them together ~ ~
