The land has compactly arranged molecules through which conduction takes place and as it is an insulator heat, the heat remains on the surface of the earth i.e. land whereas water has loosely packed molecule heat is transferred by convection and thus it takes a longer time to heat up. Also, water has a higher specific heat capacity, meaning that it requires more energy to heat water to the same temperature as a piece of land. Water also reflects more incoming radiation. The land is dark, rough, and solid, which all contribute to the absorption of the radiation. Unlike water, the land is unable to retain heat for as long as water.

An anemometer is the standard instrument used to measure wind speed or velocity.

When air is saturated, relative humidity is 100 percent and the dew point equals the air temperature. Increasing the temperature would decrease the relative humidity, not cause condensation.

The Beaufort scale is an empirical measure that relates wind speed to observed conditions at sea or on land. It ranges from 0 (calm) to 12 (hurricane-force winds). Decibels measure sound intensity, Richter scale measures earthquake magnitude, and Fujita scale (misspelled as Fajita here) measures tornado intensity.

By meteorological convention, wind direction is defined as the direction from which the wind is blowing.

Advection refers to the transport of an atmospheric property (like heat or moisture) by the horizontal movement of air (wind).

Greenhouse gases (GHGs) absorb and emit infrared radiation within the atmosphere, contributing to the greenhouse effect.

Trace gases, excluding water vapor, make up a very small fraction of the atmosphere, approximately 0.03-0.04 percent, with 0.02 percent being the closest provided option.

The rate at which temperature decreases with altitude in the atmosphere is known as the lapse rate.

The Megha-Tropiques mission is a joint satellite mission between the Indian Space Research Organisation (ISRO) and the French space agency, CNES.
