Research on Stratospheric Polar Vortex and TPVs for Arctic Cyclone Predictability

This research aims to enhance predictability of Arctic cyclones by studying the Stratospheric Polar Vortex and Tropopause Polar Vortices (TPVs). The presence of strong westerly winds in the stratosphere during fall leads to anomalous cold air outbreaks in mid-winter. TPVs serve as precursors to arct

Understanding Water Variability and Cloud Formation near Tropical Tropopause

Exploring the horizontal variability of water and its relation to cloud fraction using aircraft observations to enhance grid-scale cloud formation representation in GEOS-5. Addressing the chronic water vapor issue in GEOS-5, potential causes, motivating science questions, and methodologies to improv

Effects of Non-Spherical Ice Crystal Shape on Modeled Properties of Thin Tropical Tropopause Layer Cirrus

This study explores the impact of non-spherical ice crystal shapes on the properties of cirrus clouds in the thin tropical tropopause layer. Incorporating realistic ice crystal shapes into models affects fall speed, growth rate, and radiative absorption, influencing the time evolution of clouds. The

Understanding Atmospheric Dynamics: Vorticity, Rossby Waves, and Conservation of PV

Exploring key concepts in atmospheric dynamics such as relative vorticity, absolute vorticity, Rossby waves, and conservation of potential vorticity. Topics include the exchange of relative and planetary vorticity, implications of vorticity changes on airflow patterns, and the role of PV in understa
