Warmer Ocean Temperatures Signal New Climate Pattern.A giant horseshoe pattern of higher-than-normal sea-surface levels developing over the last year is beginning to dominate the entire western Pacific and Asiatic oceans, according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. new imagery from a U.S.-French satellite. The latest data, taken Dec. 30 through Jan. 8, show that this slower-developing condition has significant implications for global climate change, especially over North America North America, third largest continent (1990 est. pop. 365,000,000), c.9,400,000 sq mi (24,346,000 sq km), the northern of the two continents of the Western Hemisphere. , said William Patzert, an oceanographer at NASA's Jet Propulsion Laboratory “JPL” redirects here. For other uses, see JPL (disambiguation). Jet Propulsion Laboratory (JPL) is a NASA research center located in the cities of Pasadena and La Cañada Flintridge, near Los Angeles, California, USA. . Scientists believe these abnormally warm ocean temperatures may be part of a longer-lasting climate pattern. In contrast with the more spectacular but shorter El Nino and La Nina La Niña n. A cooling of the ocean surface off the western coast of South America, occurring periodically every 4 to 12 years and affecting Pacific and other weather patterns. events, this multiple-year trend may be part of a decade-long pattern known as the "Pacific decadal oscillation The Pacific Decadal Oscillation (PDO) is a pattern of Pacific climate variability that shifts phases on at least inter-decadal time scale, usually about 20 to 30 years. The PDO is detected as warm or cool surface waters in the Pacific Ocean, north of 20° N. ," Patzert said. The persistence of abnormally high and low Pacific sea-surface patterns, along with warmer and colder-than-average ocean temperatures, indicate more than an isolated La Nina in the Pacific Ocean, he said. The warmer- and cooler-than-normal sea-surface temperatures influence the Earth's atmosphere “Air” redirects here. For other uses, see Air (disambiguation). Earth's atmosphere is a layer of gases surrounding the planet Earth and retained by the Earth's gravity. It contains roughly (by molar content/volume) 78% nitrogen, 20.95% oxygen, 0.93% argon, 0. every day, while sea-surface heights measure how much heat is stored in the ocean below. "When you put these two pieces of the climate puzzle together, they will tell us both about what is influencing today's weather and how much heat is being stored in the ocean to fuel future planetary climate events, Patzert said. Swiss Reinsurance The contract made between an insurance company and a third party to protect the insurance company from losses. The contract provides for the third party to pay for the loss sustained by the insurance company when the company makes a payment on the original contract. Group and Munich Reinsurance Group, two of the world's largest reinsurers, study global climate change and assess the consequences for the risks they write. The greatest concern is the increase in weather-related natural catastrophes. The Pacific decadal oscillation waxes and wanes every 20 to 30 years. The current phase has a warm horseshoe pattern of higher-than-normal sea-surface heights connecting the northern, western and southern Pacific, in contrast to a cool wedge of lower-than-normal sea-surface levels in the eastern equatorial Pacific. In the opposite phase, the warm and cool regions are reversed. Scientists using satellite data will continue to monitor these conditions and their implications for climate in the next several years. |
