In the United States, our weather patterns usually travel from the west to the east. Sometimes, we can see variations in that a system will move in from the northwest or southwest, but Missourians ...

When the polar vortex stumbles, the weather at ground level can pivot from mild to brutal in a matter of days. A circulation ...

Finally, the wavy jet stream became locked in place by persistent high-pressure systems, anchoring storm tracks over the same regions. This led to repeated episodes of heavy rainfall and catastrophic ...

Jet streams are often referred to as the "motor" of global weather: High-altitude wind currents steer areas of high and low pressure, playing a crucial role in shaping our weather. However, how these ...

The sky may seem like a huge open playground for airplanes to fly without speed limits in any direction they wish. In reality, planes adhere to certain rules and follow fixed flight paths, much like ...

The polar night jet, the high-altitude winter wind that circles the Arctic, acts like a flywheel for the cold season in the Northern Hemisphere. As climate change erodes the temperature contrast that ...

A novel unified hydrodynamic model proposes a single mechanism to explain the contrasting equatorial jet stream directions on gas giants (eastward on Jupiter/Saturn) and ice giants (westward on Uranus ...

An email from Jerry asks why there is a jet stream and why is it called "jet stream." If we think of the air flowing around the planet as doing so in streams like rivers it may then be a little easier ...
