Cooling of the land surface at night leads to subsiding air and a sea breeze with a recirculation of the air aloft.TrueFalse

Statement Analysis

1. Understanding the Concepts: The statement describes a meteorological phenomenon where cooling of the land surface at night leads to subsiding air and the generation of a sea breeze.

2. Key Processes:

   • Cooling of Land Surface: At night, land loses heat more quickly than water due to differences in thermal properties.
   • Subsiding Air: As the land cools, the air above it becomes cooler and denser, leading to subsidence.
   • Sea Breeze Dynamics: During the day, a sea breeze occurs as cooler air from the sea moves to replace the rising warm air over the land.

3. Nighttime Effects: At night, the reversed conditions can lead to differential cooling, potentially causing the air over the land to become denser.

4. Recirculation of Air Aloft: While there might be air movement in response to temperature differences, this specific reverse effect typically occurs during the daytime sea breezes rather than nighttime cooling.

Conclusion

The statement is not entirely accurate. While cooling of the land surface can affect local air circulation, a true sea breeze primarily occurs during the day due to heating, not at night. Thus, the correct answer is:

False.
