Hurricane Danny May Be at Peak Strength

Danny now has winds near the center at 115 mph, but it is actually a rather tiny storm. Latest model runs continue a west-NW track but dry air is just to the north and wind shear will begin to impact the storm in about 48 hours. This should weaken it and the latest hires numerical model guidance shows just that. The intensity forecast from the HWRF model shows it weakening …

NASA Earth Observation Satellites See Floods in Oklahoma and Arkansas

These two images from the NASA Terra and Aqua satellites are almost exactly 2 years apart. You can easily see the difference the flooding rains have had in the Arkansas River, especially around Fort Smith. More flooding rains are likely over the next 3-4 days across the Plains of Texas and Oklahoma.

The Earth on Earth Day

I remember very well watching the CBS Evening News 45 years ago on the first Earth Day. It was a major story, and I believe Walter Cronkite led the broadcast with it. We know a lot more about our planet now than we did then, and there have been some amazing successes in protecting our environment. We now know something that was not well understood then, and that is the …

High resolution, color imagery from polar orbiting satellites allows folks like me to better tell the story of our planet to our TV audience and to our online viewers as well.

The Chesapeake Bay is Freezing Up!

Click the image above for a version large enough to print! It’s become another ‘winter to remember’ in the Northeastern U.S. The snow goes all the way to the beach here on Delmarva, with 6-8 inches covering the area. Some pics sent in from our viewers are below. Below is the ferry out to Smith Island in the Chesapeake Bay. A snowy Ocean City beach below.

Gravity Wave Ripples on The Satellite

The wave clouds on this image over Virginia are caused by winds flowing over the mountains. As the winds lift they form a cloud, and as they fall back down the air warms and dries out (and the cloud dissipates). These ripples happen because the air is fairly stable and does not want to go too high or low from its original height. So, after it goes over the mountains …

Fall Color From the Terra Satellite

Nice shot of the peak fall color in the Adirondack’s from the true color MODIS on the Terra satellite. Some pretty cirrus as well, but can you spot the jet contrails??
