Weather and Climate

So you were planning to go out to play and you see that the weather is sunny and clear, you're excited.

But the moment you set down all your bags and step out the gate, the skies turned cloudy and it started to rain.

So this sudden change in the atmosphere is known as the weather. We will learn more about it now.


Weather is an hour to hour and day to day condition of the atmosphere.

Hot or humid weather may make one irritable.

Pleasant weather will make one cheerful and even plan for a picnic.

Weather is that condition of the atmosphere that can change on a daily basis.


The average weather condition of a place for a longer period of time is known as climate.

If the weather stays hot for many days and normally the temperature remains high, the climate is said to be hot.

If the weather stays cold for many days, and the temperature remains low, the climate is cold.

So we can say the temperature is one of the factors that affects the weather and climate. Let us discuss more.

The degree of hotness or coldness is called temperature.

The temperature of the atmosphere changes from day to night and season to season.

Temperature is measured in Kelvin(°K), Celsius(°C) or Fahrenheit(°F).

The sunlight received by a place influences the temperature.

The incoming solar energy absorbed by Earth is called insolation.

Insolation intensity decreases from the equator towards the poles.

This happens because the earth is tilted, and every part of the earth does not receive the same amount of sunlight.

Temperature also decreases in the same manner, that is why Poles are covered with snow.

The temperature in the cities is higher than that in villages.

The concrete in buildings and the tar of road heats up during the day and releases heat during the night.

Apart from temperature, air pressure also affects weather and climate.

The pressure exerted by the weight of air on the earth's surface is known as Air Pressure.

The air always moves from high-pressure areas to low-pressure areas.

The air around presses with great force on our bodies.

We don't feel it because it presses us from all directions and our body exerts a backward pressure.

As we go up the blanket of air, the pressure drops rapidly.

Sea level contains the highest pressure and it decreases with height.

In areas having a lower temperature, the air is cold. It is therefore heavy. Heavy air sinks and creates a high-pressure area.

The high-pressure area is associated with clear and sunny skies.

In areas where the temperature is high the air gets heated and rises. This creates a low-pressure area.

A low-pressure area is associated with cloudy skies and wet weather.


Weather is an hour to hour and day to day condition of the atmosphere.

The average weather condition of a place for long time is called Climate.

The degree of hotness or coldness is called Temperature.

Incoming solar energy received by Earth is called Insolation.

The intensity of insolation varies from place to place due to the tilted axis of the earth and the temperature changes. accordingly.

The pressure exerted by the weight of air on the Earth's surface is called Air Pressure.

The air pressure decreases with increasing height. Therefore the air pressure is highest at sea level.

A place with high temperature has low pressure and the weather is cloudy and wet.

A place with low temperature has high pressure and the weather is clear and sunny.
