The Seasonal Winds

The air over the land is warmer in summer and colder in winter than the air over the adjacent ocean during the same seasons. During the summer, the continents thus become seats of low pressure, with winds blowing in from the colder oceans. In the winter, the continents are seats of high pressure, with winds directed toward the warmer oceans. These seasonal winds are typified by the monsoons of the China Sea and the Indian Ocean.
