FORECASTERS USING NEW WEB TOOL TO CALCULATE SNOW RATIOS
Bulletin of the American Meteorological Society April 1, 2005 | Anonymous Predicting exactly how much snow will fall in a given storm is a challenge for forecasters. They first must estimate how much liquid the storm will produce and then convert to snow amounts using a snow ratio, the amount of water that results from melting a certain depth of snow. Because this ratio can vary widely, from 3:1 (3 inches of snow per inch of liquid water) up to 100:1, meteorologists give a range of amounts in their forecasts. this web site debt to income ratio calculator
A better way of calculating snow ratios, however, using the Internet, is making snowfall prediction a little easier on NWS forecasters this winter. They now can go on the Web and obtain a snow ratio in minutes knowing just a few parameters.
Paul Roebber, professor of mathematical science at the University of Wisconsin-Milwaukee, and one of his students, Sara Bruening, came up with the improved method of predicting snow ratios. It was peer reviewed and appeared in the April 2003 issue of Weather and Forecasting.
They first applied a statistical process involving artificial neural networks (ANN), which create computer simulations within a “brain-like” system of interconnected processing units. Although ANNs have seen only limited use in meteorology, Roebber believed the system could take into account the many variables that snow-ratio prediction involves.
“I’ve always been interested in neural networks and had wanted to try using it in a forecast project,” Roebber says. “This seemed like the perfect opportunity to try it out.” He is currently collecting cases that will verify the strengths and weaknesses of the system. In one case, John Else at the Sullivan, Wisconsin, NWS office wrote that Roebber’s method gave a 13:1 ratio for a storm on 6 January, which equated to 6 or 7 inches of snow; the actual amount that fell was 7 inches. debttoincomeratiocalculatornow.com debt to income ratio calculator
One downside, forecasters admit, is that the method calculates too broad a range of ratios to be truly effective. “Forecasters already know what it’s going to say,” says Jeff Waldstreicher, deputy chief of the NWS Eastern Region Scientific Services Division. “But it does help” by verifying quantitatively what forecasters are independently inferring from the models, he says.
The Web page hosting the snow ratio calculator explains to the user what to expect, and then walks through the process to obtain a snow ratio. It also tells users that it was designed as an informal collaboration between the University of Wisconsin-Madison and the Grand Forks, North Dakota, office of the NWS, and remains a research “test-bed”-although it is gaining wider use among forecasters.
