Study on how the direction of wind shear impacts tropical cyclone intensity published in Monthly Weather Review

This is the first study to examine how the direction of the wind shear changes how much heat and moisture is available to the TC and how it influences TC intensity change.  These results provide TC forecasters another tool to predict intensity change. ■ Summary:  The amount of wind shear, the change of winds with … Continue reading Study on how the direction of wind shear impacts tropical cyclone intensity published in Monthly Weather Review

AOML reviews science conducted during Hurricane Hunter missions into Laura

Hurricane scientists at AOML provided guidance and data support for National Hurricane Center (NHC) and Environmental Modeling Center (EMC) tasked reconnaissance into Hurricane Laura, identifying critical information about the system’s location, development, and intensification. Beginning on August 20th, 11 P-3 and 6 G-IV missions were conducted, capturing the complex lifecycle of Laura until its eventual … Continue reading AOML reviews science conducted during Hurricane Hunter missions into Laura

Paper on the relationship between the Madden-Julian oscillation and rapid intensification of tropical cyclones published in Weather and Forecasting

Summary:   The Madden-Julian Oscillation (MJO) is an eastward-moving disturbance of clouds, rainfall, wind, and pressure that circles the earth in the tropics and returns to its starting point every 30 to 60 days, on average.  One part of the MJO is stormy and wet and supports the development of thunderstorms, and another part is … Continue reading Paper on the relationship between the Madden-Julian oscillation and rapid intensification of tropical cyclones published in Weather and Forecasting
