Loop Current Mixed Layer Energy Response to Hurricane Lili (2002). Part II: Idealized Numerical Simulations
Publisher: American Meteorological Society
Abstract: n this second part of a two-part study, details of the upper-ocean response within an idealized baroclinic current to a translating tropical cyclone are examined in a series of nonlinear, reduced-gravity numerical simulations. ...
Loop Current Mixed Layer Energy Response to Hurricane Lili (2002). Part I: Observations
Publisher: American Meteorological Society
Abstract: he ocean mixed layer response to a tropical cyclone within and immediately adjacent to the Gulf of Mexico Loop Current is examined. In the first of a two-part study, a comprehensive set of temperature, salinity, and current ...
Loop Current Response to Hurricanes Isidore and Lili
Publisher: American Meteorological Society
Abstract: Recent hurricane activity over the Gulf of Mexico basin has underscored the importance of the Loop Current (LC) and its deep, warm thermal structure on hurricane intensity. During Hurricanes Isidore and Lili in 2002, ...
Observational Undersampling in Tropical Cyclones and Implications for Estimated Intensity
Publisher: American Meteorological Society
Abstract: he maximum surface wind speed is an important parameter for tropical cyclone operational analysis and forecasting, since it defines the intensity of a cyclone. Operational forecast centers typically refer the wind speed ...
Improved Stepped Frequency Microwave Radiometer Tropical Cyclone Surface Winds in Heavy Precipitation
Publisher: American Meteorological Society
Abstract: urface wind speeds retrieved from airborne stepped frequency microwave radiometer (SFMR) brightness temperature measurements are important for estimating hurricane intensity. The SFMR performance is highly reliable at ...
Hurricane Sea Surface Inflow Angle and an Observation-Based Parametric Model
Publisher: American Meteorological Society
Abstract: his study presents an analysis of near-surface (10 m) inflow angles using wind vector data from over 1600 quality-controlled global positioning system dropwindsondes deployed by aircraft on 187 flights into 18 hurricanes. ...
Verification of Remotely Sensed Sea Surface Winds in Hurricanes
Publisher: American Meteorological Society
Abstract: Surface winds in hurricanes have been estimated remotely using the Stepped-Frequency Microwave Radiometer (SFMR) from the NOAA WP-3D aircraft for the past 15 years. Since the use of the GPS dropwindsonde system in hurricanes ...
A Novel Multiscale Intensity Metric for Evaluation of Tropical Cyclone Intensity Forecasts
Publisher: American Meteorological Society
Abstract: n this study, a new multiscale intensity (MSI) metric for evaluating tropical cyclone (TC) intensity forecasts is presented. The metric consists of the resolvable and observable, low-wavenumber intensity represented by the ...

On the Limits of Estimating the Maximum Wind Speeds in Hurricanes
Publisher: American Meteorological Society
Abstract: his study uses an observing system simulation experiment (OSSE) approach to test the limitations of even nearly ideal observing systems to capture the peak wind speed occurring within a tropical storm or hurricane. The ...
