摘要: [1] The 2010 Atlantic hurricane season was extremely active, but no hurricanes made landfall in the United States, raising a question of what dictated track. Here we use observations from 1970–2010 (also extending back to 1950) and numerical model experiments show that warm pool (AWP) – large body water comprised Gulf Mexico, Caribbean Sea western tropical North plays an important role An eastward expansion AWP shifts genesis location eastward, decreasing possibility for make landfall. A also induces barotropic stationary wave patterns weaken subtropical high produce steering flow anomalies along eastern seaboard States. Due these two mechanisms, are steered toward northeast without making Although La Nina event Pacific may be associated with increased number hurricanes, its relationship landfalling activity has been offset by effect AWP.
