First, MCSs are characterized by their cloud shield signatures using 10 km infrared geostationary satellite data with three-hourly time resolution. A survey of multiyear occurrence (from 1990 to 2006) of MCSs is then performed and subsequently correlated with synoptic-scale TEW disturbances. The North American Regional Reanalyses (NARR) are used to characterize the atmospheric disturbances and the overall circulation of the TEWs. The relationship between TEWs and MCSs helps to diagnose the MCS forcing on synoptic time-scales. Comparing active and inactive periods of TEWs shows promise for Relationship of TEWs and spatial-temporal variability of MCSs in the North American Monsoon

The NOAA-MAK was recovered on 31 May 2009 and re-...

The ITF varies on interannual and decadal time scales, forced by ENSO, the Asian monsoons and interannual climate variability in the Indian Ocean basin. To date, direct

The existing estimates of the volume transport from the Pacific Ocean to the South China Sea are ... more The existing estimates of the volume transport from the Pacific Ocean to the South China Sea are summarized, showing an annual mean westward transport, with the Taiwan Strait outflow subtracted, of 3.5±2.0 Sv (1 Sv=10 6 m 3 s −1). Results of a global ocean circulation model show an annual mean transport of 3.9 Sv from the Pacific to the Indian Ocean through the South China Sea. The boreal winter transport is larger and exhibits a South China Sea branch of the Pacific-to-Indian Ocean throughflow, which originates from the western Philippine Sea toward the Indonesian Seas through the South China Sea, as well as through the Karimata and Mindoro Straits. The southwestward current near the continental slope of the northern South China Sea is shown to be a combination of this branch and the interior circulation gyre. This winter branch can be confirmed by trajectories of satellite-tracked drifters, which clearly show a flow from the Luzón Strait to the Karimata Strait in winter. In summer, the flow in the Karimata Strait is reversed. Numerical model results indicate that the Pacific water can enter the South China Sea and exit toward the Sulu Sea, but no observational evidence is available. The roles of the throughflow branch in the circulation, water properties and air-sea exchange of the South China Sea, and in enhancing and regulating the volume transport and reducing the heat transport of the Indonesian Throughflow, are discussed.

The former dataset was obtained by an array of current meters moored at 350 m, 750 m and 1500 m within Makassar Strait, from December 1996 to June 1998; the latter dataset is from the TOPEX-Poseidon (T/P) altimeter

The INSTANT data reveals interannual fluctuations, with greater upwelling and sea to air heat flux in 2006.
