The trade winds enter the peninsular part of India as the south-west monsoon. [7], As part of the Hadley cell, surface air flows toward the equator while the flow aloft is towards the poles. In the circulation cell that exists between 60 and 30 north, the movement of air produces the prevailing westerlies. Trade winds: These winds are mainly caused due to the Coriolis effect and Ferrel's law. South-east trade wind This convergence zone lies parallel to the equator but moves north or south with the apparent movement of the sun. Coauthor of. Although the average strength of these winds is force 3-4, it is not uncommon for them to reach force 6 and even 7 during January to March. Webnorth-east trade winds.

The easterly winds between the two subtropical zones form the intertropical airflow and tend to be strongest in the eastern Pacific. The Coriolis effect is an imaginary or inertial force that causes winds in the northern hemisphere to be deflected to the right and in the southern hemisphere to be deflected to the left.

The Coriolis Effect makes the trade winds appear to be curving to the west, whether they are traveling to the equator from the south or north. These come primarily from the southwest in the northern hemisphere and the northwest in the southern hemisphere. The extent of the trade winds at all times of the year is influenced by the position of the Intertropical Convergence Zone (ITCZ) or doldrums.
