Intraseasonal Variability of Sea Level in the Western North Pacific

Intraseasonal Teleconnection between North American and Western North Pacific Monsoons with 20-Day Time Scale

Based on a recently released, high-resolution reanalysis dataset for the North American region, the intraseasonal variability (ISV; with a time scale of about 20 days) of the North American monsoon (NAM) is examined. The rainfall signals associated with this phenomenon first emerge near the Gulf of Mexico and eastern Pacific at about 20°N. They subsequently migrate to the southwestern United St...

Tropical Pacific Sea-Surface Temperatures and Preceding Sea Level Pressure Anomalies in the Subtropical North Pacific

A Mechanism for Explaining the Maximum Intraseasonal Oscillation Center over the Western North Pacific*

During late boreal summer (July–October), the intraseasonal oscillation (ISO) exhibits maximum variability over the western North Pacific (WNP) centered in the South China Sea and Philippine Sea, but many numerical models have difficulty in simulating this essential feature of the ISO. To understand why this maximum variability center exists, the authors advance a simple box model to elaborate ...

Robustness of the modes of Indo‐Pacific sea level variability

Reliable projections of future sea level are vital for coastal communities. Regional deviations from global mean sea level rise are caused primarily by spatial patterns in the various components of sea level change (e.g. melting land ice, thermal expansion, and so on; see Slangen et al. 2012; Perrette et al. 2013; Church et al. 2013) and by wind anomalies associated for example with various cli...

Dynamics of Intraseasonal Sea Level and Thermocline Variability in the Equatorial Atlantic during 2002–03

Satellite and in situ observations in the equatorial Atlantic Ocean during 2002–03 show dominant spectral peaks at 40–60 days and secondary peaks at 10–40 days in sea level and thermocline within the intraseasonal period band (10–80 days). A detailed investigation of the dynamics of the intraseasonal variations is carried out using an ocean general circulation model, namely, the Hybrid Coordina...
