Modern weather forecasting involves a combination of computer models, observation, and a knowledge of trends and patterns. Using these methods, reasonably accurate forecasts can be made up to about five days in advance. Beyond that, detailed forecasts are less useful, since atmospheric conditions such as temperature and wind direction are very complex.
Most of the computer models used for forecasting are run by the National Weather Service, which creates forecast models based on complex formulas. These models are used by many different weather and news services in preparing daily forecasts. Local weather observers, balloons, satellites, and weather stations also help provide data for forecasts.
You don't need to have a supercomputer or weather balloon to try your hand at forecasting, though. The most basic weather forecasting consists of simple observation. For example, you can look up at the clouds and try to recognize telltale patterns as people did in the past. High, wispy clouds usually presage good weather. An overcast sky means rain or snow is on the way. Certain weather features seem to be associated with certain types of weather, at least most of the time

Nice. Nobody in the world next to you
Days ago you said you are a college student.
I hope you are not doing your exercises by "copy-paste".
Try to understand the significance and the meaning of what you read
