Rob Rogers gave invited presentation at the opening ceremony for the Asia-Pacific Typhoon Collaborative Research Center (AP-TCRC) – 29 November 2021
On 29 November, 2021, Rob Rogers gave an invited virtual talk entitled "Advances in the Understanding and Prediction of Tropical Cyclone Intensity Change from Airborne Observations" at a new international joint tropical cyclone research organization, named the Asia-Pacific Typhoon Collaborative Research Center (AP-TCRC). The AP-TCRC is supported by the ESCAP/WMO Typhoon Committee (the Committee) and … Continue reading Rob Rogers gave invited presentation at the opening ceremony for the Asia-Pacific Typhoon Collaborative Research Center (AP-TCRC) – 29 November 2021
Study on how Hurricane Dorian organized before rapidly intensifying published in Monthly Weather Review
This study showed that a weak, disorganized tropical system in an environment that is not primed for intensification can develop a new center where conditions are more favorable for intensification. The ability to observe the center of circulation, the tilt of the vortex with height, the depth of the vortex, the wind shear, and locations … Continue reading Study on how Hurricane Dorian organized before rapidly intensifying published in Monthly Weather Review
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
Study on the unusual way Hurricane Dorian intensified published in Monthly Weather Review
