Stacy Wakefield, wife of late former Red Sox pitcher Tim Wakefield, dies of pancreatic cancer. This Weather Tidbits will discuss about the weather feature known as the norlun trough. This is an axis of shifting winds that occur on the northwest side of The farther southwest from that location one is, the less likely a significant Norlun Trough event usually is, unless topography (terrain) helps to enhance precipitation rates, as hills/mountains can assist in forcing air upward. For instance, inverted troughs draped across Southeast New York State often can produce little fanfare in New York A trough is an elongated area of lower air pressure. Since pressure is closely linked to wind, there are often changes in wind direction across a trough. If a trough forms in the mid-latitudes, a temperature difference at some distance between the two sides of the trough usually exists and the trough might become a weather front at some point. The surface Norlun trough can be seen on all 3 figures, but especially on Figure 1. The upper level instability is created by the vorticity shown on Figure 3. A secondary Norlun trough coupled What's a Norlun Trough? Severe Weather There is currently 1 active weather alert. Portland, ME 04101. 38°. Light Rain. 89%. Change. Discover the rare weather phenomenon called the NORLUN trough, where a localized region in the Northeast experiences heavy snowfall without the lake effect. Meteorologist Joe Martucci breaks down A norlun trough requires colder than usual air aloft and relatively mild ocean waters to cause unstable air to develop. Around 15,000 to 20,000 feet in the atmosphere, a low-pressure system WMTW Meteorologist Matt Zidle explains the Norlun Trough.
