A sea breeze is a wind blowing from the water onto the land.

NOAA Storm Data publication, documenting: Appearing as tornadoes of water, waterspouts are an eye-catching small-scale phenomena. KANSAS CITY It is hard to believe that we are already in the final weeks of 2021, and it is time to start looking forward into 2022. Appearing as tornadoes of water, waterspouts are an eye-catching small-scale phenomena. "La Nina years now are warmer even than years with strong El Nino events of the past," said WMO Secretary General Petteri Taalas in October.The Storm Events Database contains the records used to create the official While we do not know precisely what the effect of climate change is on these natural phenomena, the World Meteorological Organization has said that it likely amplifies their impacts, particularly El Nino's intense heat and greater rainfall.įorecasting the beginning of an episode is now possible several months in advance, enabling some degree of preparation for agriculture or water management.īut on a warming planet, the WMO says the cooling effects of La Nina will likely not be sufficient to offset the rising temperatures caused by climate change. In fact, temperatures were at an all-time high despite the beginning of a La Nina period that started at the end of the summer. Now 2020 has matched that heat record, but this time there was no El Nino. In 20, a particularly intense El Nino stoked temperatures to make 2016 the hottest year ever recorded, with experts estimating that the phenomenon added between 0.1 and 0.2 degrees Celsius. The two phenomena can also cause substantial climate fluctuations-hotter for El Nino and cooler for La Nina. In many areas, La Nina causes the opposite. Their effects are diverse and far-reaching.Īn El Nino episode can cause reduced rainfall across parts of eastern Australia, Southeast Asia, India, southern Africa and northern Brazil, but wetter conditions over parts of South America, equatorial East Africa and the southern United States. They vary in intensity and do not necessarily follow one another, so for example it is possible to have two El Nino events in succession separated by a neutral period. The phenomena can each last nine to 12 months and occur irregularly, every two to seven years, punctuated by neutral periods. The name came to describe the phenomenon of surface water warming near the coasts of South America, while the periods of intensified cooling in the same region was called La Nina. El Nino can refer to the baby Jesus in Spanish. Peruvian and Ecuadorian fishermen coined the term El Nino in the 19th Century for the arrival of an unusually warm ocean current off the coast just before Christmas. ![]() Linked to ocean surface temperatures in the central and eastern Pacific Ocean around the Equator, as well as atmospheric changes including winds and rainfall, these events play a significant part in Earth's climate system.
