Sentences with phrase «regional ocean circulation patterns»

Not exact matches

Yet, we explained there is also reasonable basis for concern that a warming world may at least temporarily increase tornado damage including the fact that oceans are now warmer, and regional ocean circulation cycles such as La Nina / El Nino patterns in the Pacific which affect upper atmospheric conditions appear to becoming more chaotic under the influence of climate change.

«The authors write that North Pacific Decadal Variability (NPDV) «is a key component in predictability studies of both regional and global climate change,»... they emphasize that given the links between both the PDO and the NPGO with global climate, the accurate characterization and the degree of predictability of these two modes in coupled climate models is an important «open question in climate dynamics» that needs to be addressed... report that model - derived «temporal and spatial statistics of the North Pacific Ocean modes exhibit significant discrepancies from observations in their twentieth - century climate... conclude that «for implications on future climate change, the coupled climate models show no consensus on projected future changes in frequency of either the first or second leading pattern of North Pacific SST anomalies,» and they say that «the lack of a consensus in changes in either mode also affects confidence in projected changes in the overlying atmospheric circulation.»»

Scientists have recently observed major changes in these glaciers: several have broken up at the ocean end (the terminus), and many have doubled the speed at which they are retreating.2, 5 This has meant a major increase in the amount of ice and water they discharge into the ocean, contributing to sea - level rise, which threatens low - lying populations.2, 3,5 Accelerated melting also adds freshwater to the oceans, altering ecosystems and changing ocean circulation and regional weather patterns.7 (See Greenland ice sheet hotspot for more information.)

Accelerated melting also adds more freshwater to the oceans, altering ecosystems and changing ocean circulation and regional weather patterns.9

A recent study on the North Pacific circulation patterns over the past 1.2 million years determined that sea ice on coastal areas can be an important factor in ocean circulation, therefore influencing climate at global and regional levels.
