Climatic factors
The climatic factors are non-living factors which are responsible for determining the climatic conditions of an area. The climatic factors include light, temperature, humidity, precipitation, wind, fire, atmosphere etc.
Light
Light is the main source of energy in the earth for the existence of life. The electromagnetic spectrum of light consists of:
Infra-red rays
Visible light
UV-rays
Infra-red rays
These are the longer wavelength (more than 780nm) and helps for keeping the environment warm.
Visible light
The visible light with wavelength 390 to 780nm is made up of a series of colors like indigo, violet, blue, green, yellow, orange and red.
UV-rays
These are the shorter wavelength of about 100-390nm and helps for ionization.
Among all above these, the visible light is the most ecological important because it is necessary for photosynthesis, so called photosynthetically active radiation (PAR). The duration of intensity and color of light keeps great ecological value to living organisms.
Ecological importance of light
Light is very important for plants in photosynthesis. The duration, intensity, and color of light affect the rate of photosynthesis.
The light plays the important role in opening and closing of stomata. Mostly the stomata are opened in the light but they are closed in the dark. So, the transpiration rate is influenced by the light.
Light influence the number and position of the chloroplast. The upper part of the leaf which receives direct sunlight has the greater number of chloroplast than that of the lower part of the leaf.
Light influenced the movement of plant parts. The effect of light on the movement of plant part is called phototropism. The stem shows positive phototropism whereas root shows negative phototropism.
Light influenced in the distribution of plants. Some plants grow well in full sunlight called heliophytes or shade hating plants eg: pine, maize etc. while some plants grow well in the shade called sciophytes or shade loving plants. Eg: moss, fern etc.
Plants show the response in the duration and intensity of light for flowering. On this basis plants are of three types:
Long-day plants- which need photoperiod more than 12hrs/day for flowering.
Short-day plants- which need photoperiod less than 12hr/day for flowering.
Day-neutral plants- plants which show very little or no any response to the duration of light for flowering.

Answer:
Climatic factors are factors that affect the climate of a particular area.
Below are climatic factors.
Explanation:
- Latitude: this one shall vary the climate depending on the closeness or how far an area is from the equator, nearness to the equator means warm climate and going further means cold temperatures.
- Ocean currents
- Wind and air masses
- Nearness to water bodies
- Elevation
- relief
