"Tropical Cyclone Intensification under Moderate Vertical Wind Shear" will be discussed by Rosimar Rios-Berrios of the National Center for Atmospheric Researchin Boulder, Colorado.
Abstract: Tropical cyclones, also known as hurricanes or typhoons, are amongst the most powerful atmospheric phenomena. Accurate forecasts of where a tropical cyclone will move towards (i.e., track), how strong the accompanying winds will be (i.e., intensity), and how much precipitation will accumulate are crucial to minimize the loss of lives and property. These forecasts, however, become particularly uncertain when a tropical cyclone moves through a region of vertical wind shear. Although vertical wind shear is generally negative for tropical cyclones, many tropical cyclones can intensify under moderate shear—the range of shear magnitudes that are neither too weak nor too strong (5–10 m s−1). Explaining why and how tropical cyclones can intensify when conditions are seemingly unfavorable is a necessary step towards understanding and predicting tropical cyclone impacts.
