You and your family are planning a picnic for tomorrow. But you want to B-31 the weather forecast (预报) first to see whether there will be rain or not. Your father turns on the television and the family listens to the B-32 make the weather report.

“It will be partly cloudy tomorrow morning, B-33 clearing by early afternoon. The high tomorrow will be 85.”

As there will be no rain, the whole family feels B-34 . Without the weather forecast, you would not know this, and you would just have to take your chances. But now you can plan your picnic B-35 worrying whether it will rain or not.

The man you can thank for this is Cleveland Abbe. He is known as the father of the weather bureau. He was the first person to publish B-36 weather forecasts in the United States.

Abbe began his daily weather bulletins (简报) in 1869. They were based on weather B-37 he drew from telegraphed reports of weather conditions. Because of their accuracy (准确), the reports were B-38 .

Congress (国会) became B-39 in Abbe’s weather reports. They made Abbe a meteorologist (someone who studies weather conditions), and he B-40 issuing (发布) forecasts three times a day. He was the first official forecaster of the U.S. Weather Service. Because he often forecast probable storms, Abbe earned the nickname of “Old Probabilities.” 1
