El Nino May Take The Stage, but His Opening Act is Not Rocking The House

Just looking at the latest on El Nino from the CPC, and I must say I’m not yet impressed. Most of the atmosphere/ocean coupled models are still forecasting an El Nino to develop, but temps in the Pacific have cooled some in the past two weeks. Perhaps more importantly, the atmosphere has not started to respond, with greater than normal rainfall continuing in the West Pacific. In an El Nino, …

Australian Drought Is Likely Result of Rising Greenhouse Gases

A new paper in Nature Geoscience has found that the increasing drought in Australia is very likely due to rising greenhouse gases, and dropping levels of stratospheric Ozone in the atmosphere, and NOT a normal climate fluctuation. Model data also showed that it will likely get worse as greenhouse gases increase over the next century. Key Findings (from GFDL release-see link below) An important new tool for prediction of regional-scale …

#Not The Polar Vortex

That message is going around twitter this Friday afternoon, courtesy of many meteorologists. My friend Stu Ostro at The Weather Channel posted a nice graphic about it that is worth sharing!

Mid-Summer Taste of Autumn Next Week? Probably!

What is going on? Is it the revenge of the polar vortex? Actually, it’s probably connected to Japanese Typhoon Neogori that at one time was packing 260 kph winds. It is moving into southern Japan now, but the global weather models all indicate that it will push a lot of warm and humid air into the high latitudes north of Japan. This will push the jet-stream northward, and the downstream …

Indefensible Ignorance

I spotted this online today, and believe me it is being shared far and wide in science circles. A statement like this from a 5th grader would be alarming, but from someone (State Senator Brandon Smith) who makes laws is downright frightening. What is more frightening is that the science literacy of his constituency is so low, he’ll likely be easily re elected. In case there are any doubts I …

Super Typhoon Neogori Heads toward Japan.

The typhoon should weaken before hitting Japan, but Kyushu (southern most island) will get a ton of rain and wind. Flooding rains have already been reported earlier in the week so the soil is already saturated. ISS Astronaut Reid Wisemen sent back this shot of an oddly shaped eye on Neogori. (Perhaps related to the fact it was undergoing an eye-wall replacement cycle.)

Photosynthesis Can be Very Pretty

Driving back from Assateague National Seashore Sunday evening, and I spotted this field of sunflowers by the Salisbury, Maryland airport. I thought I’d share!

The Weather 238 years ago today in Philadelphia- Courtesy of T. Jefferson

It was cloudy in Philadelphia. Weatherwise Magazine has an excellent article with more about Jefferson and his weather records. Truly he was America’s first Meteorologist.

True Colour View of Arthur from NASA (Doppler sees winds at 100 MPH)

Frying Pan Shoals off the North Carolina coast caught a gust to 99 mph on their weather station. They were in the eye-wall of Hurricane Arthur at the time. Here on the Delmarva Peninsula there is a real risk of extreme rip currents behind the storm. With thousands of folks streaming to the Maryland and Delaware beaches for the holiday weekend, this is a serious threat. Something to think about: …

Arthur’s Ripples

  You may need to click on the image above to really see the ripples across the top of Arthur, so do that first, before I tell you why they are there. You are looking at gravity waves, but a better way of understanding it is to compare it to the ripples you see after you throw a rock into a still pond. The rock disturbs the water and makes …
