WebThe goal of this study is to better understand the dynamics of atmospheric rivers (ARs) impinging on the west coast of North America. ARs have important roles in both local weather and global climate. The NCEP reanalysis data sets were used to diagnose several cases of ARs in recent decades. Diagnostic analyses indicate that strong meridional … Web18 jun. 2012 · We find that this relationship emerges as residue of a low frequency sub-seasonal tropical-extratropical coupled mode for which a significant extratropical influence is evident. Over the Pacific, coherent interaction is simulated between evolving persistent planetary waves and convectively coupled waves bearing a resemblance to equatorial …

Web29 aug. 2002 · Intraseasonal oscillations often exhibit a strong relationship to the phase of the ENSO cycle. Overall, there tends to be weak or absent MJO activity during moderate or strong El Niño episodes. In contrast, MJO activity is often substantial during ENSO-neutral years and during weak La Niña episodes. Web5 jan. 2024 · Therefore, sea surface temperature anomalies (SSTAs) over the Indian and Pacific oceans [e.g., the Indian Ocean Dipole (IOD) and the El Niño–Southern Oscillation (ENSO)] play an important role in the variability of the MJO. The relationship between the MJO and ENSO has been a hot topic since the 1980s and has been widely studied (Li et … prowler fowler

Web直观上说，moisture mode理论，就是跳出T的变化和传统QG观，发现MJO的q的分布不均，才是真正决定了MJO向东传以及较慢速度的真实原因。. 当然，MSE的诊断也能得到类似的结果。. moisture mode的本质，是表明Moistening of the atmosphere is the driver of the MJO's eastward propogation, not ...

Their strongest lag correlation occurs between the MJO in boreal spring and ENSO SST in winter. Theories have predicted that the most optimal spatial structure of stochastic forcing of ENSO is similar to that of the MJO (Moore and Kleeman 1999). restaurants on gulf to bay
