Mr. William Lerner — Meteorologist

Rochel Burstyn

Did your parents ever tell you “Bring your bikes inside because the weather man says it’s supposed to rain,” but the sky was blue and the sun was shining, and then ten minutes later you found yourself running through the rain to bring your bike to shelter? How do the forecasters know the weather? Meet retired meteorologist Mr. William Lerner of Baltimore, Maryland, a frum “weather man.”

on the jobHi, Mr. Lerner. How do meteorologists know what the weather will be like?

The first thing we do is collect weather data. There are weather stations all over the world’s surface, and on ships in the ocean, and weather satellites out of Earth’s atmosphere carry instruments called radiometers that scan the Earth to form images. At a predetermined time, all of these stations and ships make official weather observations at exactly the same moment. Then all of this information is put together.

In the old days, people would plot all the information, such as which clouds were going in what direction, and draw weather maps to figure out what was brewing. Now it is all computer-automated. The computer generates weather information for the next few days based on scientific and mathematic principles. Meteorologists take that information and, using their knowledge of weather patterns, are able to predict the weather.
