The Sea surface temperatures play a major role in global weather which influences two extreme phases of a naturally occurring climate cycle.

El-Nino refers to a large-scale ocean-atmosphere climate interaction associated with the episodic warming in sea surface temperatures SST across the central and east-central Equatorial Pacific. However, its reverse is not always true. Skip to main content. This service is more advanced with JavaScript available. Advertisement Hide.

Impact of El-Nino and La-Nina on Indian Climate and Crop Production

The Sea surface temperatures play a major role in global weather which influences two extreme phases of a naturally occurring climate cycle. Both terms refer to large-scale changes in sea-surface temperature across the eastern tropical Pacific and the most powerful phenomenon of the Earth. These are best known for altering the climate across more than half of the planet that also impact the weather patterns. It is a low pressure zone located at the equator where trade winds converge, and so, it is a zone where air tends to ascend.

El Nino during winter causes warm conditions over the Indian subcontinent and during summer, it leads to dry conditions and deficient monsoon. Whereas La Nina results in better than normal monsoon in India. India experienced deficient rainfall during El Nino years and whereas monsoon was normal during El Nino years and It means that in about 50 per cent of the year with El Nino during summer, India experienced droughts during monsoon.

Climate of India. Hence, we can say El Nino and La Nina impact greatly. El Nina resulted in a rise in warm air over the land and cooler moisture-bearing air blows in from the sea, bringing heavy rains or drought in the region. La Nina usually results in better than normal monsoon in India.

The Years of El Niño, La Niña, and Interactions with the Tropical Indian Ocean

The methods used in this study were statistical analysis and simulation. The results of this study were El Nino caused diminished rainfall in Cilacap regency between to mm. The result of sea level projection by employing simulation model in this study was compared with the simulation results of the IPCC that obtained a correlation coefficient r of 0. Based on the simulation results, the 8 eight sub-districts in Cilacap Regency located in the coastal area potentially endure flood due to the impacts of global warming and La Nina with a diverse predicted year of occurrence depending on the altitude of each sub-district.

Causes and Predictability of the Negative Indian Ocean Dipole and Its Impact on La Niña During 2016

It has extensive effects on the weather across the globe, particularly in North America , even affecting the Atlantic and Pacific hurricane seasons, in which more tropical cyclones occur in the Atlantic basin due to low wind shear and warmer sea surface temperatures , while reducing tropical cyclogenesis in the Pacific Ocean. It also caused heavy rains over Malaysia , the Philippines , and Indonesia. There is less risk of frost, but increased risk of widespread flooding, tropical cyclones, and the monsoon season starts earlier. Meanwhile, precipitation in the southwestern and southeastern states, as well as Southern California, is below average. The synoptic condition for Tehuantepecer winds is associated with high-pressure system forming in Sierra Madre of Mexico in the wake of an advancing cold front, which causes winds to accelerate through the Isthmus of Tehuantepec.

I am student of standard 12th at O. Jindal School Raigarh, Chhattisgarh, India. I've opted for Biology and Mathematics as my subject, and in Biology of course we deal with the topic of climate and environment. Living on Earth, it's our duty to understand the needs of keeping it healthy! Through my work I want to share some glimpse from the vast topic of climate changes we are experiencing and what are the major factors causing it so that the readers may understand its impact.

But all naturally occurring climate events now take place in the context of human-induced climate change, which is increasing global temperatures, exacerbating extreme weather, impacting seasonal rainfall patterns and complicating disaster prevention and management," said WMO Secretary-General Professor Petteri Taalas. But this was not enough to prevent from being one of the three warmest years on record. Seasonal outlooks from the GSCU are used to support planning by the United Nations and other partners in humanitarian and climate-sensitive sectors. The highest probabilities of above-normal temperatures occur in western, central and eastern Asia and over the southern half of North America. Above-normal temperatures are also likely over much of the northern high latitudes except over north-western North America , southern, central and eastern parts of South America, and equatorial and northern regions of Africa. These include increased chances of unusually wet conditions over much of South East Asia, Australia and northern South America and islands in Melanesia.

Она подумала, не ошиблась ли где-то. Начала просматривать длинные строки символов на экране, пытаясь найти то, что вызвало задержку. Хейл посматривал на нее с самодовольным видом. - Слушай, я хотел спросить, - заговорил.  - Что ты думаешь об этом не поддающемся взлому алгоритме, который, по словам Танкадо, он хотел создать.

Увидев кровь, Беккер понял, что ранен. Боли он не чувствовал и продолжал мчаться вперед по лабиринтам улочек Санта-Круса.

Пришла пора действовать. Нужно выключить ТРАНСТЕКСТ и бежать. Она посмотрела на светящиеся мониторы Стратмора, бросилась к его письменному столу и начала нажимать на клавиши. Отключить ТРАНСТЕКСТТеперь это нетрудная задача, поскольку она находится возле командного терминала. Она вызвала нужное командное окно и напечатала: ВЫКЛЮЧИТЬ КОМПЬЮТЕР Палец привычно потянулся к клавише Ввод.

Труп надо передвинуть.

Коммандер относился к этой программе с религиозным трепетом, но использовал ее не в политических целях: она служила ему для расчета времени, оценки информации и схематического отображения ситуации, выработки сложных стратегических решений и своевременного выявления слабых мест. Сьюзан не оставляло подозрение, что в компьютере шефа кроется нечто, чему в один прекрасный день суждено изменить весь мир. Да, я была с ним слишком сурова, - подумала Сьюзан.
