This provides the latent heat and moisture necessary to fuel the storm.<br \/>\n2.  **Coriolis Force:** This force is necessary to initiate the rotation of the air mass around a low-pressure center. It is negligible near the equator, which is why tropical cyclones do not typically form within about 5 degrees latitude of the equator.<br \/>\n3.  **Pre-existing Low-Pressure System:** A weak low-pressure area or disturbance is needed as a starting point.<br \/>\n4.  **Moist Air:** Sufficient moisture in the atmosphere is required to support the convective development.<br \/>\n5.  **Low Vertical Wind Shear:** Wind speed and direction should not change significantly with height. High wind shear can disrupt the storm&#8217;s structure.<br \/>\n6.  **Upper-Level Divergence:** Air must be diverging aloft above the surface low-pressure system. This allows the rising air in the thunderstorm activity to ventilate and supports further upward motion and intensification. The third statement mentions *upper convergence*, which is contrary to the required condition of *upper divergence*.<br \/>\n<\/section>\n<section id=\"pyq-additional-information\">\nThe formation process involves the release of latent heat when water vapor condenses, which warms the surrounding air, making it less dense and causing it to rise. This rising air reduces pressure at the surface, drawing in more moist air, creating a feedback loop that fuels the storm. The Coriolis force causes the inflowing air to rotate counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.<br \/>\n<\/section>\n","protected":false},"excerpt":{"rendered":"<p>Which of the following relating to the formation of tropical cyclone is\/are correct?
