Our weather glossary breaks down complex weather and climate terms in an easy-to-understand way.
When most people think about the weather, they’re thinking about conditions in the short term—the current temperature, what it’s like outside, and whether or not it looks like it’s going to rain. On the other hand, climate refers to average weather conditions in a particular area over time.
An outflow boundary is a meteorological term that refers to the boundary between two air masses created by a thunderstorm’s downdraft. If you’ve ever stood outside during a thunderstorm and felt the cool rush of air preceding a storm, you’ve experienced an outflow boundary.
A squall line is a line of strong and severe thunderstorms common in the spring and summer and often produce strong winds, lightning, heavy rain, and hail. Squall lines often form ahead of cold fronts but can develop independently if several strong thunderstorms merge.
Weather is a complex and fascinating subject, with numerous phenomena occurring all around the globe. One such event, a microburst, can be as captivating as … Read more
When most people think of thunderstorms, they imagine a large, dark storm cloud that pops up in the afternoon and evening, bringing strong winds and heavy rain. This type of storm is called an air mass thunderstorm. However, two other types of thunderstorms often precede frontal passages in the summer.
As you look up at the sky, the troposphere is crucial in nurturing the clouds above you. But beyond this breathable layer, there are five … Read more
The history of thermometers is a captivating journey that spans centuries and encompasses the contributions of brilliant minds and scientific pioneers. From the groundbreaking discoveries … Read more
Ever wonder what the types of fronts you see on the weather map mean? As part of our continuing weather education series, we thought an explainer would be helpful.
Mother Nature possesses both awe-inspiring and terrifying forces, and among them are tropical cyclones. These powerful storm systems, ranging from tropical depressions to devastating hurricanes, … Read more
The jet stream is a narrow band of strong winds in the upper levels of Earth’s atmosphere, and it blows from west to east and provides a corridor for storms to follow as they circumnavigate the globe. Jet streams form along the boundaries of warm and cold air, and the wiggles of the jet stream play a large part in the weather you experience.
Our atmosphere is constantly in motion. Weather systems are transported around the globe by this motion, with a narrow band of stronger winds called the ‘jet stream‘ providing much of this motion, which lies between cold and warm air masses.
It happens every winter. Drivers are caught off guard by icy roads and a sudden wind gust, the arrival of cold air, and a burst of snow so heavy you can’t see the car in front of you. It’s called a snow squall and is more common than people think.
Weather forecasts provide valuable information about the expected temperature and weather conditions. However, the actual temperature can sometimes differ from what the thermometer indicates. This … Read more
In the arid deserts and valleys of the Western United States, a rare and magnificent natural event occasionally graces the landscape: the superbloom. This phenomenon, … Read more
In the average winter, most of us will have to deal with frozen precipitation, not just snow. One of these types is sleet, and we’ll explain how it forms and the difference between it and a hailstone.
Winter 2020-21 didn’t turn out as many thought. Most long-range forecasters thought La Niña would lead to a mild and uneventful winter. My weather station read 62 on Christmas Day in Pennsylvania! Well, the polar vortex had other plans.
Nor’easters are intense periods of snow and high wind that can last for days. While the term is most commonly associated with coastal storms that pass by the Northeastern US’ major cities, the term is used elsewhere, such as in Europe.
Sleet vs freezing rain: which winter weather phenomena would you rather deal with? While both create a whole host of headaches, one is far more hazardous than the other.
We’ve all been through it if you live in an area that falls below freezing in winter. It’s freezing out yet raining. Within minutes, everything becomes an ice rink. Drivers lose control of their cars, everything grinds to a halt. It’s not fun.
A blizzard is a severe snowstorm that produces extensive wintry precipitation over a large area, including heavy snow and powerful winds, typically accompanied by freezing temperatures.
