Abstract:
Spectral Analysis of wind time-series data obtained with the Boundary Layer Instrument Package (BLIP) during the Barbados Oceanographic and Meteorological Experiment (BOMEX) in 1969 shows the spectra to be contaminated by ship and balloon motion only at the very high frequencies (0.11 to 0.07 Hz). Spectra for undisturbed weather show the existence of weak eddies with wave lengths centered near 300 m, while those for disturbed conditions indicate energetictwo-dimensional eddies with wave lengths of up to several hundred meters. One of the objectives of the Barbados Oceanographic and Meteorological Experiment (BOMEX), held in the summer of 1969, was to gather information about the marine tropical planetary boundary layer. Since the experiment was to take place on the open sea, standard instrumentation and techniques could not be used, The need for specially designed instrumentation gave birth to the Boundary Layer Instrument Package (BLIP), which was developed for BOMEX by the University of Wisconsin. The BLIP is a modified radiosonde that was launched by a tethered balloon during the first three BOMEX observation periods from the four corner ships andfrom the Oceanographer and Mt. Mitchell during the fourth observation period. It consist of a three_cup anemometer mounted on an A-frame that acts as a windvane, with temperature, humidity, and pressure sensors contained in a package attached to the bottom of the frame. A detailed description of the instrumentation has been given by Almazan (1972). The data obtained by the BLIP are likely to be contaminated by ship movement, balloon motion, and the interaction between the balloon and the tether line. The purpose of this study is to separate the effects of such motion from meteorological scales of motion using spectral analysis of BLIP data for both undisturbed and disturbed weather conditions.
Purpose: To make a wide range of climatic data available to researchers and the public. CURRENTNESS REFERENCE: Ground Condition Pricing is dependent on customer order specifications. Please contact NCDC for information on fees and terms for retrieving the Data Set or Product. |
