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
