The OWLeS project examines the formation mechanisms, cloud microphysics, boundary layer processes and dynamics of lake-effect systems (LeS) at unprecedented detail using X-band and S-band dual-polarization (dual-pol) radars, an aircraft instrumented with particle probes and profiling cloud radar and lidar, a mobile integrated sounding system, a network of radiosondes,and a surface network of snow characterization instruments.
Lake-effect systems form through surface-air interactions as a cold air mass is advected over relatively warm (at least partially) ice-free mesoscale bodies of water. The OWLeS project focuses on Lake Ontario because of its size and orientation, the frequency of LeS events (especially intense single bands), its nearby moderate orography, the impact of Lake Ontario LeS hazards in particular on public safety and commerce, and the proximity of several universities with large atmospheric science programs.
The OWLeS project distinguishes between two primary modes, depending on prevailing wind direction:
1) short-fetch LeS (those oriented at large angles to the long axis of the lake); and,
2) long-fetch LeS (those more aligned with the lake’s long axis). A 3rd component of this project focuses on downstream coastal and orographic effects, particularly in the Finger Lake and Tug Hill Plateau regions.

Science vehicles and platforms
Scientists will utilize in situ and remotely sensing instruments during OWLeS in order to obtain small- and large-scale kinematic and thermodynamic measurements of lake-effect snow bands
