How do they know what the weather is going to be like?

Answer 1

Off the cuff, I'd say by using their fancy pants instruments. Barometers measure atmospheric pressure; gauging relative pressures can indicate whether a high pressure system is moving towards or away from you; same general principle can be gauged using thermometers, ie. high vs. low temperature systems. Satellite systems give a pretty good indication of atmospheric moisture content, ie. where massive clouds are forming vs. where they may go; also they can indicate wind patterns via cloud 'flow.' Last, ocean currents are fairly reliable indicators of the seasons - hot water from the tropics flowing north (and south) from the tropics into regions where cold water is flowing south (and north) from the equators; fairly regular patterns have been established.

Answer 3

By studying past weather record 'patterns' to see if they repeat. for example, say a particular town has had snow every November, since their records began a hundred years ago, then it's a pretty safe bet they'll have snow this November too.

Accurate weather forecasts can only be made up to five days ahead, but general forecasts can be months in advance.

Answer 4

They know from tv and the Radio and what are we suppose to do if we dont have a tv or a radio?

Answer 5

The know what the weather is going to be like because they study the weather patterns. They also have satellites that are taking pictures of the approaching weather and storm fronts.

Answer 6

This is a good question my mom told me satellite is one of the things you should ask your teacher to learn about it in........................SCIENCE OR SOCIAL STUDIES

Answer 7

The 'weather people', also known as meteorologists, use radar and satellite imagery to predict the weather.
