Climatic Regions of India : Trewartha’s Classification

 ,

The Köppen climate classification is a system that classifies climates into five main climate groups: tropical, dry, temperate, continental, and polar. Each group is then divided into sub-groups based on temperature and precipitation.

The Köppen climate classification is one of the most widely used climate classification systems in the world. It was developed by German-Russian climatologist Wladimir Köppen in the early 20th century. The system is based on the annual and monthly mean temperature and precipitation of a location.

The five main climate groups in the Köppen climate classification are:

• Tropical: A climate with an average temperature of 18°C (64°F) or higher throughout the year. Tropical climates are found near the equator, where the sun’s rays are most direct.
• Dry: A climate with an average annual precipitation of less than 25 cm (10 in). Dry climates are found in areas where there is little rainfall, such as deserts and semi-deserts.
• Temperate: A climate with an average annual temperature between 10°C (50°F) and 18°C (64°F). Temperate climates are found in areas between the tropics and the poles.
• Continental: A climate with a large difference between the summer and winter temperatures. Continental climates are found in areas that are far from the ocean, such as the interior of North America and Eurasia.
• Polar: A climate with an average annual temperature below 10°C (50°F). Polar climates are found in the Arctic and Antarctic regions.

Each of the five main climate groups is then divided into sub-groups based on temperature and precipitation. For example, the tropical climate group is divided into the tropical rainforest climate, the tropical savanna climate, and the tropical monsoon climate.

The Köppen climate classification is a useful tool for understanding the Earth’s climate. It can be used to identify areas with similar climates, to track changes in climate over time, and to predict future Climate Change.

The Thornthwaite climate classification is a system that classifies climates based on the amount of water that is available for Plants to use. The system divides climates into three main groups: humid, sub-humid, and arid. Each group is then divided into sub-groups based on the amount of precipitation and potential evapotranspiration.

Potential evapotranspiration is the amount of water that would evaporate from a surface if there were no restrictions on the water supply. The Thornthwaite climate classification is based on the idea that the amount of water that is available for plants to use is determined by the difference between precipitation and potential evapotranspiration.

The three main climate groups in the Thornthwaite climate classification are:

• Humid: A climate with an average annual precipitation that is greater than the potential evapotranspiration. Humid climates are found in areas where there is more rainfall than Evaporation.
• Sub-humid: A climate with an average annual precipitation that is less than the potential evapotranspiration, but greater than half of the potential evapotranspiration. Sub-humid climates are found in areas where there is more evaporation than rainfall, but the rainfall is still sufficient to support plant Growth.
• Arid: A climate with an average annual precipitation that is less than half of the potential evapotranspiration. Arid climates are found in areas where there is very little rainfall and evaporation is high.

Each of the three main climate groups is then divided into sub-groups based on the amount of precipitation and potential evapotranspiration. For example, the humid climate group is divided into the humid continental climate, the humid subtropical climate, and the humid tropical climate.

The Thornthwaite climate classification is a useful tool for understanding the Earth’s climate. It can be used to identify areas with similar climates, to track changes in climate over time, and to predict future climate change.

What is climate?

Climate is the average weather conditions in a place over a long period of time. It is affected by factors such as latitude, altitude, and proximity to water.

What are the different Types of Climate?

There are many different ways to classify climates. One common system is the Köppen climate classification system, which divides climates into five main types: tropical, dry, temperate, continental, and polar.

What are the characteristics of each type of climate?

Tropical climates are warm and wet year-round. Dry climates are hot and dry in the summer and cold and dry in the winter. Temperate climates have four distinct seasons: spring, summer, fall, and winter. Continental climates have hot, humid summers and cold, dry winters. Polar climates are cold and dry year-round.

What are the Causes of Climate Change?

Climate change is caused by human activities such as burning fossil fuels, deforestation, and agriculture. These activities release greenhouse gases into the Atmosphere, which trap heat and cause the planet to warm.

What are the effects of climate change?

Climate change is causing a number of changes to the planet, including rising sea levels, more extreme weather events, and changes in plant and animal life. These changes are having a significant impact on people and the Environment.

What can we do to address climate change?

There are a number of things we can do to address climate change, including reducing our reliance on fossil fuels, investing in RENEWABLE ENERGY, and protecting forests. We can also make changes to our own lifestyles, such as driving less, using less energy, and eating less meat.

What is the future of climate change?

The future of climate change is uncertain. If we do not take action to reduce greenhouse gas emissions, the planet will continue to warm. This could have devastating consequences for people and the environment. However, if we take action now, we can still avoid the worst effects of climate change.
