It is as simple as opening an app on your phone or tuning in to the weather channel on your TV. Many variables is why we see the 14-day weather forecast change so frequently.

The meteorologist takes past and present information to help predict that future weather pattern This method is used when tracking individual storms converging in a city.

A weather radar is a handy tool for now casting as it can predict how heavy the rain and wind is based on its echo. An echo or echo-top is a radar that determines the top of an area of precipitation.

The higher the cloud, the stronger the updraft, which is the speed in which wind is traveling upwards in a storm. Large updrafts in a storm make more significant wind gusts and hail likely.

All this real-time information makes it essential to now cast as sometimes thunderstorms are so severe it requires an immediate reaction from the public. From airplanes in the sky trying to land and take off in fog, or cargo ships avoiding large storms out on the ocean, we are continually looking at the weather.

You check the clock and realize you're running late. Before you can even protest, you're told that the temperature is going to drop when it begins to rain later this afternoon.

Weather forecasts help us prepare for the future, whether it's a few hours from now or the rest of the week. Not only do they warn us of potentially -dangerous weather headed our way, they also give us an idea of what to expect in terms of temperature and chance of precipitation, so we can dress and equip ourselves appropriately.

The people who study the weather and put together forecasts are scientists known as meteorologists. You might have gotten excited, anticipating a snow day and the chance to do some sledding.

Unfortunately, you woke up to clear skies, no snow, and a full day of school ahead. Forecasts are a prediction based upon an educated guess.

Fortunately, modern technology has allowed forecasters to become much more accurate over the last decade. Today, meteorologists use complicated mathematical equations to help predict the weather as part of a process known as numerical forecasting.

Numerical forecasting requires powerful supercomputers and tons of observational data from land, sea, and air weather stations around the world. Technologically-advanced weather stations are established by meteorologists all over the world.

They collect and share data to help improve forecasts. Some tools they use include barometers that measure air pressure, anemometers that measure wind speed, Doppler radar stations to monitor the movement of weather fronts, and psychrometers to measure relative humidity.

To get data from the seas and the upper atmosphere, data -collection tools and instruments may be attached to ships, airplanes, and even buoys in the middle of the ocean. All these different types of tools around the world produce millions of pieces of weather -related observational data every single day.

Supercomputers, such as those at the National Centers for Environmental Prediction in Camp Springs, Maryland, process that data to produce forecasts based upon complicated mathematical models. Current data is compared to similar patterns that have occurred in the past to determine what will likely happen in the future.

Meteorologists (also called '' forecasters '') are scientists who study weather patterns and atmospheric conditions. Most local weather is determined by location or the geographic conditions of the area.

For example, we know that the northeast and upper Midwest regions of the U.S. are prone to heavy snowfalls in the winter; hurricanes are common in the southeast; hot temperatures (both dry and humid) are characteristic of the south and southwest, and tornadoes are prevalent in the Great Plains. This detailed information begins with various forecasting tools meteorologists have at their disposal.

Surface maps are used to view areas of low and high pressure. Every day, millions of observations from satellites are recorded into these models, and they are frequently updated to improve future weather forecasting.

Meteorologists have dozens of these models to look at, each of which can produce a different result every time atmospheric conditions are altered slightly. But if a meteorologist increases the wind speed slightly, the model may show mostly cloudy or even rainy skies later in the day.

After looking at their forecasting model results, meteorologists rely on collaboration with their fellow scientists. At AccuWeather, meteorologists meet three times a day to decide on forecasts that are a little more difficult to determine.

If you ever thought weather forecasts involved mostly guesswork and a gut feeling, you were partially right. While it may not seem as scientific as their other methods, meteorologists will use their years of experience in observing repeating weather patterns to guide them in their forecasting.

Today’s post is a continuation of my communication with Ms. Jordan’s 6th Grade Science Class at South Central Middle School! South Central MS is located in Emerson, Georgia, in Barton County.

Meteorologists are able to predict the changes in weather patterns by using several tools. They use these tools to measure atmospheric conditions that occurred in the past and present, and they apply this information to create educated guesses about the future weather.

The best we can do is observe past and present atmospheric patterns and data, and apply this information to what we think will happen in the future. Most people are familiar with thermometers, barometers, and anemometers for measuring temperature, air pressure, and wind speed, respectively.

Meteorologist David Ross from the News Office in Key West, Florida, released the balloon into the air. The weather balloon rises high into the air, recording atmospheric data throughout the trip.

Meteorologists also use satellites to observe cloud patterns around the world, and radar is used to measure precipitation. A sample image of the Global Forecast System (GFS) model precipitation output.

That was an excellent question, and I hope my answer inspired you to study the weather, too! Predicting the weather is certainly a tricky task, and all meteorologists strive to do the best job they can.
