Accurate weather prediction can be made only if all the air measurements i.e. temperature, humidity and wind direction are considered. 

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.

The major greenhouse gases are water vapour, which causes about 3670% of the greenhouse effect; carbon dioxide (CO$ _2$), which causes 926%; methane (CH$ _4$), which causes 49%; and ozone (O$ _3$), which causes 37%. Water vapour is the most abundant greenhouse gas, it acts as a feedback to the climate. Water vapour increases as the earth's atmosphere warms, making these the most important feedback mechanisms to the greenhouse effect. Carbon dioxide is released through natural processes such as respiration and volcano eruptions and through human activities such as deforestation, land use changes, and burning fossil fuels. This is the most important long-lived cause of climate change.
