Quantifying Environmental Control on Tropical Cyclone Intensity Change
Composite analysis is used to examine environmental and climatology and persistence characteristics of tropical cyclones (TCs) undergoing different intensity changes in the western North Pacific (WPAC) and North Atlantic (ATL) ocean basins. Using the cumulative distribution functions of 24-h intensity changes from the 2003–08 best-track data, four intensity change bins are defined: rapidly inte...
متن کاملDynamical Control of Rapid Tropical Cyclone Intensification by Environmental Shears
Improve our understanding of the physical processes by which (a) 3-D environmental shears, in particular the low-level meridional shear and upper-level vertical shear affect inner core structure and intensity, and (b) the mesoscale vortices, outer spiral rainbands, inner spiral rainbands, and the eyewall interact and affect TC development and intensity change. General questions to be addressed ...
متن کاملHuman influence on tropical cyclone intensity.
Recent assessments agree that tropical cyclone intensity should increase as the climate warms. Less agreement exists on the detection of recent historical trends in tropical cyclone intensity. We interpret future and recent historical trends by using the theory of potential intensity, which predicts the maximum intensity achievable by a tropical cyclone in a given local environment. Although gr...
متن کاملThe Dvorak Tropical Cyclone Intensity Estimation Technique
T HE DVORAK TECHNIQUE LEGACY. The Dvorak tropical cyclone (TC) intensity estimation technique has been the primary method of monitoring tropical systems for more than three decades. The technique has likely saved tens of thousands of lives in regions where over one billion people are directly affected by TCs (commonly called hurricanes, typhoons, or cyclones). The Dvorak technique’s practical a...
متن کاملMidlevel Ventilation's Constraint on Tropical Cyclone Intensity
Midlevel ventilation, or the flux of low-entropy air into the inner core of a tropical cyclone (TC), is a hypothesized mechanism by which environmental vertical wind shear can constrain a tropical cyclone’s intensity. An idealized framework based on steadiness, axisymmetry, and slantwise neutrality is developed to assess how ventilation affects tropical cyclone intensity via two possible pathwa...
