Tropical cyclones are intense low-pressure systems that originate over warm tropical oceans (Statement 1 is correct). The Coriolis force is essential for the rotation and development of a tropical cyclone; hence, they typically do not form near the equator where the Coriolis force is negligible (Statement 2 is correct). Tropical cyclones form and develop in tropical regions, generally between 5° and 30° latitude, not in middle latitudinal regions (Statement 3 is incorrect). A well-developed tropical cyclone features a central ‘eye’, which is a region of calm, clear, and subsiding air (Statement 4 is correct).

Key characteristics of tropical cyclones include formation over warm ocean waters, requirement of Coriolis force for rotation, occurrence in tropical latitudes, and the presence of a calm ‘eye’ at the center of mature storms.

Middle latitude cyclones (also known as extratropical cyclones) form in the middle latitudes (typically between 30° and 60° latitude) and are associated with frontal systems. They derive energy from temperature contrasts, unlike tropical cyclones which derive energy from latent heat released by condensation of water vapor.
