对NCEP/NCAR再分析资料中的北半球夏季(6—8月)海平面气压(sea level pressure,SLP)场进行EOF分解,其主要模态之一为夏季北半球环状模态(Northern Hemisphere annular mode,NAM),体现出大气的纬向对称结构,SLP异常场在北极和中高纬地区呈现反相变化分布。 更多例句>> 4...
Figure 8.6shows the sea-level pressure and surface winds at 9-h intervals starting at 00 UTC Nov. 10 (note that the field of view is smaller than in the previous charts). At all three map times a pronounced wind-shift line, the expression of thecold frontin the surface wind field, is...
The bi-monthly Multivariate El Niño-Southern Oscillation index (MEI; positive/negative values correspond to El Niño/La Niña events, respectively)68is the time series of the leading combined Empirical Orthogonal Function (EOF) of five different variables (sea level pressure, SST, zonal and ...
The Victoria mode in the North Pacific linking extratropical sea level pressure variations to ENSO 来自 学术范 喜欢 0 阅读量: 289 作者:R Ding,J Li,Y Tseng,S Cheng,Y Guo 摘要: The Victoria mode (VM) represents the second dominant mode (empirical orthogonal function, EOF2) of North Pacific...
Unrotating principal component analyses (or empirical orthogonal functions, EOFs) were applied to demeaned, normalized sea-level pressure (SLP), surface air temperature (SAT), and sea-ice area (SIA) for the periods 1901-97 and 1953-97. The leading SLP EOF mode is the AO. The leading SIA...
The sea level pressure in the East Asia–Northwest Pacific region directly reflects the circulation characteristics of the lower atmosphere, and its dynamical characteristics have considerable effects on the atmospheric circulation situation, the evoluti
Estimation of Precipitation by Kriging in the EOF Space of theSea Level Pressure Field The term downscaling denotes a procedure in which local climatic information is derived from large-scale climate parameters. In this paper, the possibility... G Biau,E Zorita,H Von Storch,... - 《Journal ...
A CCA model with EOFs of SST as the predictor at the same lead-times is compared to SLP as a predictor and shows the auto-correlation of the system. A CCA using the first five extended empirical orthogonal functions (EEOFs) of sea level pressure over the Indian Ocean basin for an ...
To account for the atmospheric contribution to the sea level trend, the Dynamic Atmospheric Correction (DAC) is applied. It is an important correction, adjusting for the effects of atmospheric pressure and wind on the ocean's surface51. It ensures that the satellite-derived sea level data refle...
