In eurasia, the land becomes cold in the winter and develops a seasonal high-pressure system from which surface flow is directed off the land. in the summer, in contrast, the opposite occurs: the landmasses are heated and develop a low-pressure cell, which permits air to flow onto the land. this "switch" in directions of airflow into or off of the continent gives rise to

the monsoon

Explanation:

According to my research on changes of continental airflow, I can say that based on the information provided within the question this "switch" gives rise to the monsoon. The monsoon is defined as a seasonal shift in the dominant wind direction, that is usually accompanied by various kinds of weather.
