Consider the diurnal atmospheric pressure gradients operating along the coastal belt of Kerala: Statement I: During daytime, land surfaces heat up faster than adjacent ocean waters, creating a low-pressure zone over land that draws cool maritime air inward. Statement II: The Coriolis force completely negates the formation of sea breezes within tropical latitudes close to the equator. Which of the following is correct?

💡 Solution & Explanation

Statement I correctly describes the fundamental thermal contrast mechanism driving sea breezes, where differential heating establishes local pressure gradients. Statement II is incorrect because while the Coriolis force approaches zero precisely at the equator, Kerala lies approximately 8 to 12 degrees north of the equator, where the Coriolis effect is weak yet sufficient to impart a slight directional deflection to prevailing winds. Diurnal wind reversals are a signature microclimatic feature of narrow tropical coastal plains.
