RISWeather Bike: A Bicycle-Based Weather Station for Observing Local Temperature Variations
Publisher: American Meteorological Society
Forcing of the Wintertime Antarctic Boundary Layer Winds from the NCEP–NCAR Global Reanalysis
Publisher: American Meteorological Society
Abstract: Antarctica is noted for strong and persistent winds in the lower atmosphere. The wind directions are controlled by the underlying ice terrain and are deflected in general 20°?50° to the left of the fall line. The Antarctic ...
An Analysis of the Nonhydrostatic Dynamics in Numerically Simulated Antarctic Katabatic Flows
Publisher: American Meteorological Society
Abstract: A series of two-dimensional numerical experiments was conducted in order to describe the role of nonhydrostatic dynamics in simple Antarctic katabatic flows. The results presented include a comparison of the thermodynamic ...
The Role of Katabatic Winds on the Antarctic Surface Wind Regime
Publisher: American Meteorological Society
Abstract: Antarctica is known for its strong and persistent surface winds that are directed along topographic pathways. Surface winds are especially strong during the winter period. The high directional constancy of the wind and the ...
An Analysis of Low-Level Jets in the Greater Ross Ice Shelf Region Based on Numerical Simulations
Publisher: American Meteorological Society
Abstract: An analysis of the presence and location of low-level jets (LLJs) across the Ross Ice Shelf region in Antarctica is presented based on the analysis of archived output from the real-time Antarctic Mesoscale Prediction System ...
Estimating Sensible and Latent Heat Fluxes Using the Integral Method from in situ Aircraft Measurements
Publisher: American Meteorological Society
Abstract: n September 2009, several Aerosonde unmanned aerial vehicles (UAVs) were flown from McMurdo Station to Terra Nova Bay, Antarctica, with the purpose of collecting three-dimensional measurements of the atmospheric boundary ...
Analysis of the Ross Ice Shelf Airstream Forcing Mechanisms Using Self-Organizing Maps
Publisher: American Meteorological Society
Abstract: he Ross Ice Shelf airstream (RAS), a prominent transport mechanism of cold, continental air to the north, is the most common wind pattern over the Ross Ice Shelf, Antarctica. The forcing mechanisms of the RAS include ...
Diagnosis of the Katabatic Wind Influence on the Wintertime Antarctic Surface Wind Field from Numerical Simulations
Publisher: American Meteorological Society
Abstract: Katabatic winds have long been recognized as one of the key climatic variables of the low-level Antarctic environment. Antarctic surface winds display a high degree of persistence with mean directions related to the local ...
Identification of Surface Wind Patterns over the Ross Ice Shelf, Antarctica, Using Self-Organizing Maps
Publisher: American Meteorological Society
Abstract: he interaction of synoptic and mesoscale circulations with the steep topography surrounding the Ross Ice Shelf, Antarctica, greatly influences the wind patterns in the region of the Ross Ice Shelf. The topography provides ...
Evaluation of WRF Model Resolution on Simulated Mesoscale Winds and Surface Fluxes near Greenland
Publisher: American Meteorological Society
Abstract: outhern Greenland has short-lived but frequently occurring strong mesoscale barrier winds and tip jets that form when synoptic-scale atmospheric features interact with the topography of Greenland. The influence of these ...
