Why the weird weather in July? An unusually wiggly jet stream, which meteorologists call a "meridional flow." Meridional flow is the term used to describe the air flow pattern far above the Earth ...

Meteorologists often refer to these patterns as "upper-level flow." Meridional Flow vs. Zonal Flow In the context of winter weather, two main types of upper-level flow are relevant: meridional ...

The researchers found that the relatively slow gas movement, known as the meridional flow, sped up a few years before the last solar minimum began in 2008. What’s more, the flow was ...

Helioseismology was used to measure the Sun's meridional flow (in miles per hour). This flow controls the evolution of the global magnetic field and the number of sunspots. This material relates ...

When the winds cross the latitude lines at a sharp angle, the wind pattern is termed meridional." He said storms tend to move faster (west to east) when associated with a zonal flow. Meridional ...

Grace Anello, meteorologist for WAAY 31 in Huntsville, said Meridional flow in the jet stream is causing a north to south air flow movement that’s bringing some Canadian smoke haze into north ...

During la niña, the jet stream is often more wavy with more ups and downs embedded within the flow. This is referred to as meridional flow in the weather community. When we find ourselves under ...

Normally, it flows fairly straight, but sometimes it develops a wavy pattern, called meridional flow. That’s when things get interesting — and extreme. A man wearing a Venezuelan flag starts a ...

There are different configurations to the jet stream and we’re going to see the evolution of what meteorologists call a “meridional flow.” When this happens, it often leads to significant ...
