How does Southern Oscillation affect monsoon?
As those conditions change, with the monsoon being linked to El Nino-Southern Oscillation phenomena, summer temperatures over much of India may rise to as high as 45 degrees Celsius, while the Indian Ocean is much cooler.
What happens if the monsoons are late in Southern Asia?
When the summer monsoon is late or weak, the regions economy suffers. Fewer people can grow their own food, and large agribusinesses do not have produce to sell. Governments must import food. Electricity becomes more expensive, sometimes limiting development to large businesses and wealthy individuals.
How does Southern Oscillation influence the monsoon Class 9?
Such changes in the pressure conditions over the southern oceans also affect the monsoon. This periodic change in pressure conditions is known as the Southern Oscillation or SO. The difference in pressure over Tahiti and Darwin is computed to predict the intensity of the monsoons.
How does La Nina affect Indian monsoon?
La Nina may further increase the amount of moisture available over the Indian subcontinent. This could lead to excess snowfall and rainfall, resulting in a winter cooler and wetter than normal.
What is the effect of El Nino Southern Oscillation in Indian monsoon?
ENSO and India El Nino: Strong El Nino events contribute to weaker monsoons and even droughts in India Southeast Asia. La Nina: The cold air occupies a larger part of India than the El Nino cold air.
What is Southern Oscillation mention the climatic features associated with it?
El Niño–Southern Oscillation (ENSO) is an irregular periodic variation in winds and sea surface temperatures over the tropical eastern Pacific Ocean, affecting the climate of much of the tropics and subtropics. The warming phase of the sea temperature is known as El Niño and the cooling phase as La Niña.
How does climate change affect Indian monsoons?
Simply put, climate change means we will have more monsoon rain in future, but also more variability in rainfall dispersal over the monsoon period, as witnessed in 2021, and more localised extremely heavy rain in short spans of time, as seen in coastal Maharashtra, west Gujarat and Hyderabad this year.
What are the factors affecting Indian monsoon Class 9?
Class 9 Climate: Factors Affecting the Climate of India
- Latitude.
- Altitude.
- Pressure and Winds.
- Hot Weather Season (Summer)
- Cold Weather Season (Winter)
- Advancing Monsoon (Rainy)
- Retreating/Post-Monsoon Season (Transition Season)
- Answers.
What is Southern Oscillation in geography class 9?
Southern oscillation refers to shifting the surface air pressure between the tropical eastern Pacific and eastern Indian oceans. A warm ocean current flows past the Peruvian coast, in place of the cold Peruvian current for every 2 to 5 years.
How does El Niño affect Indian monsoons?
El Nino: Strong El Nino events contribute to weaker monsoons and even droughts in India Southeast Asia. La Nina: The cold air occupies a larger part of India than the El Nino cold air.
How does El Nino affect Indian monsoon Upsc?
This causes heavy rains in Peru during the El Nino years robbing the Indian subcontinent of its normal monsoon rains. The larger the temperature and pressure difference, the larger the rainfall shortage in India.
