Meteorologists are undoubtedly familiar with the "highs" and "lows" of weather on Earth, thanks to changes in atmospheric pressure. But have you ever wondered why we're always so infatuated with all those blue H's and red L's on a weather map? Differences in air pressure are a cornerston...
再结合第四段"Air in the cold air mass is often drier than air in front of it.As the air masses meet,the wind usually changes direction and rain or thunderstorms often occur." (冷空气团中的空气往往比它前面的空气干燥。当气团相遇时,风通常改变方向,经常下雨或雷暴)可知,气团运动时,天气会发生...

The national weather map shows a high pressure (压力) area all along the eastern coastline which brought them very pleasant, sunny weather from New York to Florida.But showers and thunderstorms are taking place from the Ohio River all the way south to the Gulf coast, bringing heavy amounts ...
Weather reports often mention high or low pressure systems headed toward a city or town. If you’re in the path of one of these systems, expect a change in weather conditions. High and low pressure systems operate using similar principles, but the effects they produce differ significantly. ...
Differences in atmospheric pressure in the troposphere are more fundamental to the Earth's weather than any other factor. Relatively minor differences in this pressure at the surface arise from the global imbalance in heating, and cause the circulation of air at large scales around these...
