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.

El Niño–Southern Oscillation

The El Nino and La Nina are part of the global climate system which occurs when the Pacific Ocean and the atmosphere above it change from their neutral 'normal' state for several seasons. Difference between El Nino and La Nina. Temperature at Sea Surface: It is warmer than normal sea-surface temperatures. It is a warming of the Pacific Ocean between South America and the International Date Line , centred directly on the Equator, and moves towards several degrees of latitude to either side of the equator. Temperature at Sea Surface: It is cooler than normal sea-surface temperatures. It originated when cooler than usual ocean temperatures occur on the equator between South America and the International Date Line. Trade winds: It originated when tropical Pacific Ocean trade winds die out and ocean temperatures become unusually warm.

Also, it refers to the migration of Central Pacific equatorial warm water to the east, and the warm phase of the Southern Oscillation. This current typically appears in late December or early January, and its association with Christmas and the Epiphany Skip to main content Skip to table of contents.

The Ocean and Weather: El Niño and La Niña

The two phases relate to the Walker circulation , which was discovered by Gilbert Walker during the early twentieth century. The Walker circulation is caused by the pressure gradient force that results from a High-pressure area over the eastern Pacific Ocean, and a low-pressure system over Indonesia. Mechanisms that cause the oscillation remain under study. The extremes of this climate pattern's oscillations cause extreme weather such as floods and droughts in many regions of the world. Developing countries dependent upon agriculture and fishing, particularly those bordering the Pacific Ocean, are the most affected.

This naturally occurring phenomenon involves fluctuating ocean temperatures in the central and eastern equatorial Pacific, coupled with changes in the atmosphere. Scientific progress on the understanding and modelling of this phenomenon has improved prediction skills to within a range of one to nine months in advance, giving society the opportunity to prepare for associated hazards such as heavy rains, floods and drought. The outlook for the second half of the year is currently uncertain. In summary:. More detailed interpretations of the implications for regional climate variability will be carried out routinely by the climate forecasting community over the coming months and will be made available through the National Meteorological and Hydrological Services.

Why are they so destructive? And why do they matter to humanitarian work? We break it down in this explainer. While focused on a small section of the Pacific near the Equator, these shifts have global ramifications. They influence both temperature and rainfall.

The El Niño – Southern Oscillation (ENSO) is a recurring climate pattern involving changes in the temperature of waters in the central and eastern tropical Pacific.

What are El Niño and La Niña?

It is a warming of the central to eastern tropical Pacific Ocean. Yes, the last episode began just two years ago, in They both tend to develop during the spring March-June , reach peak intensity during the late autumn or winter November-February , and then weaken during the spring or early summer March-June.

In the Pacific Ocean near the equator, temperatures in the surface ocean are normally very warm in the western Pacific and cool in the eastern Pacific [2].

Доброе утро, сэр. Извините, что пришлось вас разбудить. Почему я звоню. Я только что выяснил, что ТРАНСТЕКСТ устарел. Все дело в алгоритме, сочинить который оказалось не под силу нашим лучшим криптографам! - Стратмор стукнул кулаком по столу.

ENSO and Global Seasonal Climate Updates

Он думал, что сможет обойтись без ее участия - принимая во внимание ее склонность к самостоятельности - и сам найдет этот ключ, но уже столкнулся с проблемами, пытаясь самостоятельно запустить Следопыта. Рисковать еще раз ему не хотелось. - Сьюзан, - в его голосе послышалась решимость, - я прошу тебя помочь мне найти ключ Хейла. - Что? - Сьюзан встала, глаза ее сверкали. Стратмор подавил желание встать с ней. Он многое знал об искусстве ведения переговоров: тот, кто обладает властью, должен спокойно сидеть и не вскакивать с места.

 - Именно это я и пыталась тебе втолковать. - Возможно, ничего страшного, - уклончиво сказал он, - но… - Да хватит. Ничего страшного - это глупая болтовня. То, что там происходит, серьезно, очень серьезно. Мои данные еще никогда меня не подводили и не подведут.

Парень поставил бутылку на стол. - Вы из полиции. Беккер покачал головой. Панк пристально смотрел на. - Вы похожи на полицейского. - Слушай, парень, я американец из Мериленда. Если я и полицейский, то уж точно не здешний, как ты думаешь.
