The climatic factors include rainfall and water, light, temperature, relative humidity,air, and wind.
Rainfall and Water
Rainfall is the most common form of precipitation. It is the falling of water in droplets on the surface of the Earth from clouds. Other forms of precipitation are freezing rain, sleet or ice pellets, snowfall, and hail.
Light
Light is a climatic factor that is essential in the production of chlorophyl and photosynthesis.
Temperature
The degree of hotness or coldness of a substance is called temperature . It is commonly expressed in degree Celsius or centigrade (C) and degree Fahrenheit (F) . This climatic factor influences all plant growth processes such as photosynthesis, respiration, transpiration, breaking of seed dormancy, seed germination, protein synthesis, and translocation.
In general, plants survive within a temperature range of 0 to 50 C.
Excessively low temperatures can also cause limiting effects on plant growth and development. At temperatures below the freezing point of water, there is change in the form of water from liquid to solid.
Air
The air is a mixture of gases in the atmosphere.About 75% of this air is found in the troposphere, the innermost layer of the atmosphere which extends about 17 km above sea level at the equator and about 8 km over the poles.
In addition, about 99% of the clean, dry air in the troposphere consists of 78% nitrogen and 21% oxygen. The remainder consists of argon (slightly less than 1%), carbon dioxide (0.036%), and traces of other gases.
The oxygen and carbon dioxide in the air are of particular importance to the physiology of plants. Oxygen is essential in respiration for the production of energy that is utilized in various growth and development processes. C
Relative Humidity
The amount of water vapor that the air can hold depends on its temperature; warm air has the capacity to hold more water vapor than cold air.
Relative humidity (RH) is the amount of water vapor in the air, expressed as the proportion (in percent) of the maximum amount of water vapor it can hold at certain temperature.
Wind as Climatic Factor
Air movement or wind is due to the existence of pressure gradient on a global or local scale caused by differences in heating. On a global scale it consists of the jet stream flow and movement of large air masses. On the local scale only a smaller quantity of air moves. Surface winds are lower and less turbulent at night due to the absence of solar heating.
