Using observations and models to understand the warming Arctic

Nick Szapiro-March 12-School of Meteorology (Defense)

Towards furthering understanding and extending predictions of the polar environment, this thesis explores the variability in Arctic summer sea ice driven by coherent upper-level potential vorticity anomalies common in the Arctic termed tropopause polar vortices (TPVs).

Hristo Chipilski-March 8

Using data from the 6 July 2015 PECAN mission, this study examines how the assimilation of novel boundary layer (BL) profilers affects the forecasts of a bore-initiated convection event. To account for the multi-scale nature of the phenomenon, data impacts are discussed separately with respect to the (i) bore environment, (ii) explicitly resolved bore and (iii) bore-initiated convection.

Samuel Degelia-March 8-Convective Meteorology (Mesoscale Dynamics) Seminar

Numerical weather prediction models often fail to correctly forecast convection initiation (CI) at night in the Great Plains. To improve our understanding of such events, researchers collected unique observations from thermodynamic and kinematic profilers as part of the Plains Elevated Convection at Night (PECAN) experiment. The assimilation of these observations can aid in analyses of key features that are not easily observed by conventional datasets This talk presents forecasts of a nocturnal CI event from PECAN in which assimilating the PECAN dataset improves the timing, location, and orientation of CI.

Tyler Bell- March 8- Boundary Layer, Urban Meteorology, and Land-Surface Processes

In recent years, increased attention has turned to studying the planetary boundary layer (PBL) as advanced instruments have become more affordable. Commercial availability of scanning Doppler lidars and the recent widespread availability of small unmanned aerial vehicles (UAS) has opened up a world of opportunity to observe and study the complex processes that occur in the PBL. These two paradigms (remote sensing and UAS), have the potential to revolutionize boundary layer observations.
