Human 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...
متن کاملAutoregressive Modeling for Tropical Cyclone Intensity Climatology
An autoregressive model is developed to simulate the climatological distribution of global tropical cyclone (TC) intensity. The model consists of two components: a regression-based deterministic component that advances the TC intensity in time and depends on the storm state and surrounding large-scale environment and a stochastic forcing. Potential intensity, deep-layer mean vertical shear, and...
متن کاملTropical Cyclone Intensity and Structure Changes in relation to Tropical Cyclone Outflow
The overarching objective of this project is to identify impacts to tropical cyclone structure and intensity throughout the tropical cyclone lifetime. A common factor is the impact of midand upperlevel environmental conditions that affects formation and intensification of a tropical cyclone. It is hypothesized that during the formation process, the environmental interaction has maximum impact o...
