Clouds are important in that they can form precipitation and bring rain to crops and plants. They also shade the earth, affecting the temperature and keeping sunlight from directly hitting plants.
Thus cloud cover tends to smooth out the diurnal variation of temperature,keeping the temperature low by day and comparatively high at night.In the absence of such a cloud cover, the diurnal variation of temperature(daily temperature change) becomes extremely high over the deserts.
