RISOn the Relative Accuracy of Satellite and Raingage Rainfall Measurements over Middle Latitudes during Daylight Hours
Publisher: American Meteorological Society
Abstract: Empirical relationships between visible and/or IR data and rainfall rate are derived by comparing gage-calibrated radar data with colocated satellite information over Montreal, Canada. The accuracy of 1739 point gage-satellite ...
Statistics of Radar Echoes on Day 261 of GATE
Publisher: American Meteorological Society
Abstract: Statistics of echoes observed on day 261 of GATE, using the radar aboard the Canadian ship Quadra, are described. This is a case in which detailed observations have been obtained from many sensors during the growth of a ...
The Evaluation of Two Years of Real-Time Operation of a Short-Term Precipitation Forecasting Procedure (SHARP)
Publisher: American Meteorological Society
Abstract: Digital weather radar data have been used with a simple pattern recognition procedure to automatically generate precipitation forecasts in the zero to three hours range. Such a technique has been in real time operation for ...
The Sources of Error in Rain Amount Estimating Schemes from GOES Visible and IR Satellite Data
Publisher: American Meteorological Society
Abstract: Recent work in GOES satellite rain amount estimation techniques suggests that these satellites primarily show skill in estimating areas of rain, rather than rain amounts directly. This hypothesis is quantitatively investigated ...
Vertical Motion of Patterns in Radar Records of Showers
Publisher: American Meteorological Society
Abstract: A technique is described for finding an ?effective pattern fallspeed? from arrays of radar data taken at different times and different heights. A weather radar whose antenna scans in three dimensions at many elevation ...
Combining Satellite and Radar Data for the Short-Range Forecasting of Precipitation
Publisher: American Meteorological Society
Abstract: An algorithm yielding probability of rain from GOES visible-infrared imagery and simultaneous radar data is applied over a satellite image the size of eastern Canada. It is then mapped by means of a conic projection an a ...
Comparison Between Maritime Tropical (GATE and Barbados) and Continental Mid-Latitude (Montreal) Precipitation Lines
Publisher: American Meteorological Society
Abstract: Radar and synoptic data for precipitation lines from GATE, Barbados and Montreal are compared. The Montreal and Barbados lines have similar orientation but travel from opposite directions. The GATE lines have orientations ...
Deep Convection on Day 261 of GATE
Publisher: American Meteorological Society
Abstract: Aircraft, radar, satellite and ship data, gathered on 18 September 1974 during GATE, have been brought to bear an clouds of the middle and upper troposphere associated with a cloud cluster occurring near the ridge axis of ...
The New Zealand Southern Alps Experiment
Publisher: American Meteorological Society
Abstract: The Southern Alps Experiment is being mounted to study the influence of New Zealand's Southern Alps on local weather and climate. This paper describes these alpine influences and outlines proposed field and modeling ...
