RISA Sea-Land Transition Observed during the COAST Experiment
Publisher: American Meteorological Society
Abstract: A sea wind situation was analyzed during the COAST (Cooperative Operations with Acoustic Sounding Techniques) experiment. The thermal internal boundary layer (TIBL) which develops inland from the coast was investigated by ...
Turbulent Moisture Measurements aboard Instrumented Aircraft with a Capacitive Sensor
Publisher: American Meteorological Society
Abstract: The authors show how a capacitive device measuring moisture can be used aboard instrumented atmospheric aircraft as an alternate sensor for turbulence measurement. Using a calibrated Lyman-α sensor as a reference, the time ...
Use of the Inertial Dissipation Method for Calculating Turbulent Fluxes from Low-Level Airborne Measurements
Publisher: American Meteorological Society
Abstract: Airborne measurements are currently used for computing turbulence fluxes of heat and momentum. The method generally used is the eddy correlation technique, which requires sophisticated equipments to calculate the absolute ...
A Simple Method Based on Routine Observations to Nowcast Down-Valley Flows in Shallow, Narrow Valleys
Publisher: American Meteorological Society
Abstract: simple relation to diagnose the existence of a thermally driven down-valley wind in a shallow (100 m deep) and narrow (1?2 km wide) valley based on routine weather measurements has been determined. The relation is based ...
Local-Scale Valley Wind Retrieval Using an Artificial Neural Network Applied to Routine Weather Observations
Publisher: American Meteorological Society
Abstract: AbstractWe hereby present a new method with which to nowcast a thermally driven, downvalley wind using an artificial neural network (ANN) based on remote observations. The method allows the retrieval of wind speed and ...
