Abstract: Using 3 h wind data (1970?74) from nine first-order NWS stations in and around Illinois, monthly frequency histograms of wind speeds for each station, and for each half-day (0700?1800 and 1900?0600 LST) were constructed. ...

Abstract: The frequency and intensity of early winter (November) coldwaves were investigated for the north central United States. Twenty-two such storms occurred from 1901 to 1985, and were most frequent in the 1950s and early 1960s, ...

Abstract: A relationship is identified between the area of the North Atlantic with surface temperatures greater than 26.8°C and the frequency of tropical storms and hurricanes. The relationship is direct and near-exponential. When ...

Abstract: The replacement of liquid-in-glass (LIG) thermometers with electronic thermometers in the National Weather Service (NWS) cooperative (co-op) network and concern for homogeneous temporal temperature records prompted this ...

Abstract: Known sources of data from arrays of instantaneous precipitation intensity recorders in southern Germany, east-central Illinois, northeastern Illinois, central Florida, and Hilo, Hawaii are obtained. These data are analyzed ...

Abstract: Near-surface airstream source regions of the Northern Hemisphere have been identified using 16-year mean resultant winds from 3° latitude by 3° longitude grids. Tracing the airstreams back to their divergent centers reveals ...

Abstract: Estimates of mean monthly surface streamlines for the Southern Hemisphere were prepared from gridded mean surface geostrophic winds, from ship and land-based observations collected over several decades. The streamlines ...

Abstract: We compare the Completeness and quality of one year's daily temperature and precipitation observations from the National Climatic Data Center (NCDC) database with those received by the Illinois State Water Survey's (ISWS) ...

Abstract: Through a computer-based system, weather data from Illinois are collected daily, checked, and summarized into various climatic products within hours after collection. This system was controlled for two years to demonstrate ...

Abstract: Mean monthly surface wind streamline charts for the North Africa-Mediterranean region are extracted from a previously prepared Northern Hemisphere set. These charts define mean airstream sources and mean confluences or ...
