Tropical Indian Ocean Influence on Northwest Pacific Tropical Cyclones in Summer Following Strong El Nino
In the summer following a strong El Nino, tropical cyclone (TC) number decreases over the Northwest (NW) Pacific despite little change in local sea surface temperature. Our analysis suggests El Nino-induced tropical Indian Ocean (TIO) warming as the cause. The TIO warming forces a warm tropospheric Kelvin wave that propagates into the western Pacific. Inducing surface divergence off the equator...

متن کاملStratified coastal ocean interactions with tropical cyclones
Hurricane-intensity forecast improvements currently lag the progress achieved for hurricane tracks. Integrated ocean observations and simulations during hurricane Irene (2011) reveal that the wind-forced two-layer circulation of the stratified coastal ocean, and resultant shear-induced mixing, led to significant and rapid ahead-of-eye-centre cooling (at least 6 °C and up to 11 °C) over a wide s...
متن کاملOcean spray and the thermodynamics of tropical cyclones
Serious gaps in knowledge about ocean spray at wind speeds over 40m/s remain difficult to fill by observation or experiment; yet refined study of the thermodynamics of Tropical Cyclones (including typhoons and hurricanes) requires assessment of the hypothesis that ’spray cooling’ at extreme wind speeds may act to reduce (i) the initial temperature of saturated air rising in the eyewall and so a...
متن کاملInfluence of upper ocean stratification interannual variability on tropical cyclones
Climate modes, such as the El Ni~ no Southern Oscillation (ENSO), influence Tropical Cyclones (TCs) interannual activity through their effect on large-scale atmospheric environment. These climate modes also induce interannual variations of subsurface oceanic stratification, which may also influence TCs. Changes in oceanic stratification indeed modulate the amplitude of TCs-induced cooling, and ...
