Paper on how tropical cyclones can intensify in high shear released online in Monthly Weather Review

When the wind within about 150 miles of the center of a tropical cyclone (what we call the near environment) is very different at the bottom and the top of the storm (what we call wind shear), the storm usually weakens, especially if the storm is already weak. However, sometimes this doesn't happen, and the …

Paper on the unusual eyewall replacement cycles in Hurricane Irma published in Monthly Weather Review

Summary: Accurate forecasts of hurricane strength are necessary to protect people in the path of a storm. The strongest winds in a hurricane are found near the center of the storm, in a ring of dangerous weather called the eyewall. As a hurricane grows older, it is common for the eyewall to eventually weaken and get …

Paper on how downdrafts in hurricanes affect intensity published in Monthly Weather Review

Summary: This study looks at differences between tropical cyclones that strengthen and those that do not using data collected by dropsondes, small instruments released from hurricane hunter aircraft that measure wind, temperature, and moisture as they fall to the surface. Important Conclusions: 1. The fuel that supports tropical cyclones is the heat and moisture from …
