A monsoon climate is distinguished by a major seasonal change in the direction of a region’s predominant winds, which results in a significant variation in rainfall. and climate change is affecting Monsoon in India In several regions, Climate change is affecting Monsoon in India. results in annual rainfall totals surpassing 1.5 m (5 ft).know some things which are climate change monsoon.
Monsoons, most frequently linked with the Indian Ocean, generate different wet and dry seasons in a variety of equatorial locales Climate change affects monsoons.
The Indian Monsoon is the most visible of the world’s Monsoon systems, affecting India and its surrounding water bodies. It blows from the northeast during the milder months and from the southwest during the warmer months of the year. reason affecting monsoon in India.
But the overall world Monsoon affecting by climate change which also affects Indian Monsoon here are some bullets point that show how climate change is affecting monsoons in India.
- An intense low-pressure system has formed over the Tibetan Plateau.
- The Indian Ocean The permanent high-pressure cell in the South of the.
- Subtropical jet stream.
- African Easterly jet (Tropical easterly jet)
- Inter-Tropical Convergence Zone (ITCZ)
Intense low-pressure formation over the Tibetan Plateau, Climate change affecting the Indian monsoon.
The Tibetan Plateau acts as a heat engine. The plateau’s elevation is between 4000 and 5000 meters, and it encompasses an area of around 2.5 million square kilometers. It has little vegetation and is borde by snow-capped mountain ranges. As a result, it is fiercely heat in the summer and is around 20C to 30C warmer than the air over the adjacent region.
During the summer, when the sun appears to be moving towards the tropic of cancer, the temperature above the Tibetan Plateau remains high for an extended period of time. This leads air to climb to the upper troposphere, where it creates a high-pressure region. As a result, an anti-cyclonic situation and land-ocean pressure differential are creating. Intense how the low-pressure formation climate change affects the Indian monsoon.
Inter-Tropical Convergence Zone (ITCZ)
- What is the cause of the ITCZ ( Intertropical Convergence Zone)?
- The ITCZ (Intertropical Convergence Zone) is created by the convergence of northeast and southeast trade winds near the Equator. To have a deeper understanding, we must first learn about trade winds and air masses.
- The ITCZ (Intertropical Convergence Zone) is created by the convergence of northeast and southeast trade winds near the Equator. To have a deeper understanding, we must first learn about trade winds and air masses. Climate change affects the Indian Monsoon.
What are the effects of the ITCZ on the weather?
1. It impacts rainfall in the equatorial area due to location fluctuation, resulting in the tropics’ wet and dry seasons rather than the cold and warm seasons of higher latitudes.
What is a hurricane and how does it form?
2. Long-term changes have resulted in catastrophic droughts or flooding.
3. It aids in the creation of cyclones since it is a zone of change in wind speed and direction.
The ITCZ is a small zone where two hemispheres’ trade winds converge, resulting in irregular weather patterns with stagnant calms and furious thunderstorms.

Subtropical jet stream.
The presence of the tropical easterly Jet Stream across the Indian peninsula during summer and the migration of the westerly Jet Stream to the north of the Himalayas.
Aside from that variations in pressure conditions over the southern oceans have been shown to impact the monsoons. The tropical eastern Indian Ocean has low pressure whereas the tropical eastern South Pacific Ocean has high pressure. However, pressure reversals occur on occasion, and the eastern Pacific has lower pressure than the eastern Indian Ocean. The Southern Oscillation, or SO, is a type of weather pattern. periodic variation in pressure conditions. The pressure differential between Tahiti (Pacific Ocean, 18°S/149°W) and Darwin (Indian Ocean, 12°30’S/131°E) is use to forecast the strength of the monsoons. If the pressure differential were negative, it would indicate late and below-average monsoons.
El Nino, a warm ocean circulation that travels through the Peruvian coast in place of the cold Peruvian current every 2 to 5 years, is a phenomenon associate with the SO. El Nino is link to variations in pressure conditions. As the result, the phenomenon is known as ENSO (El Nino Southern Oscillations).
African Easterly jet (Tropical easterly jet)
Therefore, The Tropical Easterly Jet (jet stream) is the meteorological term for an upper-level easterly wind that occurs from late June to early September.
Low-pressure disturbances that form as far east as Sudan in east Africa and migrate over the continent into the Atlantic Ocean cause tropical waves in the Atlantic basin. The African Easterly Jet creates or enhances them.
For instance, A tropical easterly wave is caused by the African jet’s combination of baroclinic and barotropic instability. The period of African easterly waves is three to four days, the horizontal wavelength is 2000-2500 km, and the highest amplitude is in the lower troposphere. tropical jet or effect of the Indian monsoon.
What produces the easterly African jet?
Because of the heating of the West African land. mass during this time of year, a surface temperature and moisture gradient between the Gulf of Guinea and the Sahara Desert emerge. To maintain thermal wind balance, the environment generates vertical wind shear.
What exactly is the tropical easterly jetstream?
In addition, the Tropical Easterly Jet (TEJ) forms swiftly when the Sub Tropical Jet (STJ) shifts to the north of the Himalayas (Early June). The Tropical Easterly Jet moves from east to west over Peninsular India at a speed of 6 to 9 kilometers per hour (4 to 6 miles per hour) and over Northern Africa. Climate affects Indian Monsoon.
These are the findings of how claimant change monsoon
Summer monsoons may bring torrential rains, destroying homes, damaging infrastructure, washing away crops, and destroying Water, Sanitation, and Hygiene (WASH) infrastructure. therefore Dry weather during the winter monsoons can cause drought and crop failure due to a lack of precipitation.
Because of the various land masses in the northern and southern hemispheres. distinct seasons occur when the Earth rotates and circles around the Sun. in other words To explain this phenomenon, consider that the northern hemisphere has a bigger land surface area than the southern hemisphere. above all, As a result, the northern hemisphere has been warm more. finding how Climate change affects Indian Monsoon.
Temperature rise and seasonal monsoonal variations in Southeast Asia are anticipating to produce frequent changes. and shifts in monsoon precipitation up to 70% below, normal levels in the late 21st and early 22nd centuries. Not only will this have an impact on the Indian summer monsoon.
Therefore, the trends in rainfall totals were obtained from many sources. might help explain the evolution of monsoon rainfall in Southeast Asian countries.
Climate change affects the Monsoon in India ..?
This study shed some light on the links between global warming and monsoon rainfall. A multitude of meteorological phenomena, including the Arctic Oscillation, Siberian High, and Western Pacific Subtropical High, as well as the complicated Asian terrain, clearly impact the distribution of monsoon rainfall.
Understanding the change and projecting altering monsoon trends may be critical to controlling floods that affect millions of people, cause damage to lives and property, destroy the environment and farmlands and have a long-term influence on food security.
