Formed in 1983 and currently with 90 members, the Special Interest Group for the History of Meteorology and Physical Oceanography (History Group) encourages the study of the history and heritage of meteorology and physical oceanography. It provides a forum for discussion of all aspects of the history of meteorology and physical oceanography, co-operates with similar institutions and publishes a...

This paper gives a brief system overview of REINAS (Realtime Environmental Information Network Analysis System) and some details on the instrumentation and visualization aspects. REINAS is a continuing engineering research and development system with the goal of designing, developing and testing an operational prototype system for data acquisition, data management , and visualization. As such, ...

We are developing dynamic relational knowledge discovery methods for use on mesoscale weather data. Severe weather phenomena such as tornados, thunderstorms, hail, and floods, annually cause significant loss of life, property destruction, and disruption of the transportation systems. The annual economic impact of these mesoscale storms is estimated to be greater than $13B (Pielke and Carbone, 2...

Weather is certainly the most important factor over which man has no control, and hence it has created dominance on the success or the failure of agricultural enterprises. Most important efforts since long time have been on weather and rain forecasting. However, the unpredictable nature of rainfall has not changed. Meteorologists can neither solve nor evaluate the problem of effective rainfall ...

A rockslide-debris avalanche destroyed the remote village of Guinsaugon in Southern Leyte, Philippines, on 17 February 2006. Although search and rescue procedures were implemented immediately, the scale of the landslide and a lack of information about its nature resulted in unfocused and imprecise efforts in the early days of the operation. Technical support was only introduced five days after ...

The United States Weather Surveillance Radar-1988 Doppler (WSR-88D) radar network has been upgraded to dual-polarization capabilities, providing operational and research meteorologists with a wealth of new information regarding the types and distributions of hydrometeors within precipitating storms, as well as a means for improved radar data quality. In addition to the conventional moments of r...

Regional rainfall forecast is an important task for meteorologists. While statistical methods are usually in vogue, for this, the concept of data mining is applied to see the efficacy. The objective of this work is to develop a forecast method for the rainfall of the Northeast (NE) season over the Cauvery delta region of South India. There are three main parts in this work. The first part is in...

The presence or absence of a BWER within a storm is important for severe weather forecasting. The three dimensional structure of a BWER is often not clearly deened in radar data and a fuzzy logic approach where the various uncertainties associated with a BWER's radar proole (capping, three-dimensional structure, vertical height, reeectivity ranges, proximity to a mesocyclone, etc.) are taken in...

Abstract Infrared and microwave sounder measurements from polar-orbiting satellites are used to retrieve profiles of temperature, water vapor, trace gases utilizing a suite algorithms called the National Oceanic Atmospheric Administration (NOAA) Unique Combined Processing System (NUCAPS). Meteorologists operationally use retrievals similar radiosonde assess atmospheric stability aid them in iss...
