Gravity waves – Part 4
This is the second in a series of blog posts explaining what atmospheric gravity waves are, a question I get frequently. The first blog is here, and the two since then have been more wave-related stories than anything else. But, … Continue reading
Tropical Depression #2 Forms in the Atlantic
Just before 4 AM Central Time, the National Hurricane Center began issuing advisories on Tropical Depression #2 in the far eastern Atlantic: …TROPICAL DEPRESSION FORMS OVER THE FAR EASTERN ATLANTIC OCEAN… AT 500 AM EDT…0900Z…THE CENTER OF TROPICAL DEPRESSION TWO … Continue reading
Pleasant temperatures
For the second time since June 1, temperatures have reached the 50s across much of northern and central Alabama the past two mornings (it reached 49 yesterday morning in Cherokee County). These temperatures are rare in July. Looking at weather … Continue reading
Heat bursts
Jamie Sandford asked for a discussion of the physics of “heat bursts,” a fascinating weather phenomenon that has been observed several times this year in the Plains (see Bill Murray’s recent post on some intense heat bursts here. A heat … Continue reading
Gravity Waves – Part 3
OK. I promise my next gravity wave post will actually continue the explanation that I started here of what atmospheric gravity waves are and how they affect the weather. But, despite the fact that it’s not weather-related and may be … Continue reading
Save some energy
No matter what you think about global warming, saving some energy makes sense, especially when it comes to saving money. Being a meteorology person, I’ve come up with some common sense ways of saving energy, from electricity to gasoline. Some … Continue reading
Bugs on radar
If you have looked at radar pictures lately (at least over the past few days) over Alabama, you may have noticed some interesting low-reflectivity (blue, less than 15 dBZ) returns at some distance from the radar. It looks a little … Continue reading
Close Up Rainbow
The first photo is of a rainbow over the Warrior River near Bluff Creek on Monday. It may be the closest, or largest, I’ve ever seen. The second one is only about 15 minutes later, looking in another direction.
Gravity Waves – Part 2
In response to many questions about gravity waves and their effects on weather, I am putting together some blog posts to explain them. This one is really more just interesting observations, and the next part will go into atmospheric gravity … Continue reading
Heat Wave Physics
(Scroll down to read a fun post by JB on James’ anniversary and birthday!) Wow. After a pleasantly cool May with temps in the 40s as late as May 17 and 7.98″ of rain for the month at the airport, … Continue reading
