The literature study on the wind potential in the Sahel consists of two parts: A survey of the climate and in particular of the wind regime in the Sahelian region in Africa and the major factors by which the climate is determined. The so-called Inter-Tropical Convergence Zone shows to be the major meteorological phenomenon: its annual passage over the region results in strong seasonal patterns in precipitation, temperature, cloudiness, atmospheric moisture and the wind regime; A study of the availability and reliability of the wind data for the Sahel and the build-up of a wind data base.

A seasonal model for the zonal wind in the height range 35 to 75km is presented. This is based on data from between thirty and fifty falling sphere and parachute experiments conducted during the period March 1962 to December 1966.
A similar model for the meridional wind is also discussed but it is rejected.

This report contains surface wind data for the China Lake Complex of the Naval Weapons Center (NWC), China Lake, California. The data, collected from 1964 through 1982, are presented in graphs and tables. These illustrations depict monthly as well as daily time segment compilations of wind directional frequencies and average speeds. This information will be useful to Center personnel in planning, scheduling, and evaluating mission-related tests.

On the evening of January 7th, 2006, a wind gust of 98 mph was recorded by a radio station in Carson City at 800 PM LST. The instrumentation was destroyed and there was damage to several buildings in a two block area down wind from the radio station. A fitness center was also damaged and 8 cars in the parking lot had their windows blown out. The damage was very localized.

The report discusses foehn-type winds that occur near mountain ranges in the western United States. Type I is the Great Basin High type mono and type II is the Jet-Stream mono. These winds usually occur along the Sierra Nevada ranges. In this report is included a checklist to help forecasters predict an on-coming mono wind. The checklist mainly consists of topographic charts that point out the target areas and the conditions under which a mono wind is most probable.

This report presents findings and recommendations developed at a workshop onresearch needs in wind engineering. Representatives from universities, the private sector, and Federal agencies presented program overviews and participated in working group sessions addressing various aspects of wind engineering research and wind disaster mitigation. Research needs and topics for technology transfer were identified and prioritized. It was concluded that current funding of wind engineering research in the United States falls far short of what is needed to effectively address the problem of spiraling losses due to wind damage. There is, however, considerable wind engineering knowledge now available for implementation by the model building codes and by the building industry in general.

The Wave Propagation Laboratory (WPL) of the National Oceanic and Atmospheric Administration's Environmental Research Laboratories has completed the Phase I investigation of the feasibility of measuring global atmospheric wind fields using a satellite-borne coherent lidar system. The investigation used detailed analytical and physical models to simulate the wind-measurement process. NOAA-DMSP objectives and requirements, and the operational space environment were considered. Coherent lidar systems were shown to be capable of measuring the global wind field. The details of the Phase I study are presented.

The algorithms used in the NASA experimental wind shear radar system for detection, characterization, and determination of windshear hazard are discussed. The performance of the algorithms in the detection of wet microbursts near Orlando is presented. Various suggested algorithms that are currently being evaluated using the flight test results from Denver and Orlando are reviewed.

SeaWinds on QuikSCAT (QSCAT) is a dedicated satellite remote sensing mission for measuring ocean surface wind speed and direction, using a spinning, pencil-beam Ku-band scatterometer. It is a replacement mission for NASA Scatterometer (NSCAT), which was launched on board of the Japan's Advanced Earth Observation System (ADEOS-1) in August 1996 and returned 10 months of high quality data before the mission was terminated in June, 1997 due to the failure of the ADEOS-1 spacecraft. Since the next NASA scatterometer mission, SeaWinds on ADEOS-2 (SeaWinds), will not be launched until November 2000, NASA decided to fill the data gap by launching the QSCAT mission. Furthermore, after year 2000. the potential exists for using both the QSCAT and SeaWinds to provide approximately 6 hours global coverage of the marine winds. QSCAT is currently scheduled for launch in April, 1999 from Vandenberg Air Force Base, using Titan-II launch vehicle. The purpose of this paper is to first present the mission objectives, the spacecraft and instrument design, ground receiving systems, the science data processing system, and the data products. We will then present the post-launch calibration and verification results of the QSCAT end-to-end sensor system. Finally, we present some of the key results obtained from the first two months of the mission, which include ocean surface wind measurements, ice detection and classification, global snow cover detection, and flood detection.
