It is part of most people's morning routine to take a look at what the weather is expected to bring that day. You might be working at an outdoor BBQ and wondering if you're going to need to move things inside or be interested in going skiing in the heart of winter. But sometimes the weather that you're looking at is not so accurate at predicting what is to come. Here is a little about predicting the weather and how much stock you should put in these reports.
The science behind predicting the weather is called meteorology. It uses a number of different sources and instruments to determine what might be coming a few hours or days down the road. These range from a thermometer like you might find in your own home or a medical office to Doppler Radars and ships at sea reports. There are several different indicators that together will show you which patterns might be coming your way.
One of the things that weather looks at is atmospheric pressure. When you're looking at the daily local weather report on the news this refers to those high and low pressure systems that go through. If there is a low pressure system coming over your home, you might experience high winds, warm temperatures, precipitation or cloudy skies. High pressure systems are usually associated more with clear skies and calm conditions.
Weather is usually predicted these days using a lot of technology. Computer systems are able to analyze the data from all over the world and cross reference that with patterns that have been reported over the years. If you're looking at several different sources for the weather than you will find today that they are quite similar. This is because most sources are using the same base information with their own computer systems. But the results generally come out the same.
One thing about the weather is that it can never really be predicted with one hundred percent accuracy. If you're planning on getting in a GTA airport taxi in a few days to head on vacation and there is a hurricane or tornado warning than you won't know for sure if that will materialize until you get there. Some weather patterns change suddenly at the last minute and some stay right on course with predictions.
