Air-Sea Interactions in Tropical Cyclones
Significant progress has been made in the area of upper ocean responses and air-sea interactions during the passage of tropical cyclones (TC) since the first edition published in 1992. In terms of the upper ocean impacts on intensity, considerable attention has focused on the three-dimensional cold wake structure and the negative feedback due to ocean mixed layer cooling by shear-induced vertic...
متن کاملThe Shape of Continents, Air-sea Interaction, and the Rising Branch of the Hadley Circulation
This chapter begins with a brief history of Intertropical Convergence Zone (ITCZ) research. It then goes on to summarize recent progress in understanding why the ITCZ is locked in the Northern Hemisphere in the eastern Pacific and Atlantic Oceans, and how this northward-displaced ITCZ affects the space-time structure of tropical climate variability.
متن کاملAtmospheric Feedbacks over the Tropical Pacific in Observations and Atmospheric General Circulation Models: An Extended Assessment
The dynamical and radiative feedbacks from the deep convection over the tropical Pacific are quantified using ENSO signal in that region for both the observation and 16 climate models. Different from a previous analysis, we recognize the nonlinear relationship between deep convection and SST over that region, and perform the evaluation using the data from the warm phase and the cold phase separ...
متن کاملA statistical assessment of tropical cyclone activity in atmospheric general circulation models
The properties of tropical cyclones in three low-resolution atmospheric general circulation models (AGCMs) in seven ocean basins are discussed. The models are forced by prescribed, observed sea surface temperatures over a period of 40 yr, and their simulations of tropical cyclone activity are compared with observations. The model cyclone characteristics considered include genesis position, numb...
متن کاملImproving the Detection and Tracking of Tropical Cyclones in Atmospheric General Circulation Models
Dynamical seasonal forecasts of tropical storm frequency require robust and efficient algorithms for detection and tracking of tropical storms in atmospheric general circulation models (AGCMs). Tropical storms are generally detected when dynamic and thermodynamic variables meet specified criteria. Here, it is shown that objectively defined modeland basin-dependent detection criteria improve sim...
