Greetings everyone! I hope all of you are having a great start to the week and the weather is good, if not interesting, in your neck of the woods. The North American severe weather season has gotten into full swing with several days already having had all modes of severe weather occur. There’s plenty of climate change stories in the news as well with over 120 nations ready to sign the UN accord on climate change. On that note, let’s get started.
For your consideration, here are this week’s links…
A job well done! Watch the SpaceX land it’s rocket on a floating pad in full 4K resolution!
This NASA researcher claims ionized air molecules may help predict earthquakes in advance.
Many people play the romanticist view of mid 19th century United Kingdom, and England in particular, as an era of chivalrous gentlemen & alluringly coquettish women. Nothing could be further from the truth in this retrospective of a London-based sewage disaster.
A recent study suggests that the Earth’s soils could store tremendous amounts of greenhouse gasses.
For my fellow musicians. “The Eco Guide To Guitars.”
Even in the 21st century with a plethora of information available, there’s uncertainly and doubt in being an environmentalist.
National Hurricane Preparedness Week may not be until May, but it’s never too soon to prepare. The National Hurricane Center’s preparedness website has everything you need to know.
A good read on the inexorable climate/weather/public health link and how climate change can harm your health.
An interesting concept that has it benefits…and inevitable drawbacks. Forecasting tornadoes in the long-term.
Speaking of forecasting, here’s an interesting read on Panasonic’s claim of having created the world’s best weather model.
There are many facets of climate change that are very clear-cut while others are more vague.
A good read from Climate Central. “Climate change is a major threat to human health, with extreme heat likely to kill 27,000 Americans annually by 2100, according to a report released by the White House.”
Slow but steady progress as over 120 nations will sign the UN’s accord to fight global warming.
El Niños and La Niñas are particularly difficult to predict at this time of year, so exactly what happens remains to be seen.
That’s a wrap for this post! I’d like to welcome my new followers in social media. If you’d like more information, please see the links below.

Contrary to popular opinion, the ingredients for severe convective storms don’t exist in a endless supply. This Forecast Discussion (FD) from the Tulsa NWS is a good example. Reading through the FD, you will note,
“AVAILABILITY OF LOW LEVEL MOISTURE CONTINUES TO BE THE LIMITING
FACTOR WITH THIS SYSTEM. IF NOT FOR THE LACK OF MOISTURE… OTHER
FACTORS WOULD BE FAIRLY CONDUCIVE FOR SEVERE WEATHER ACROSS OUR
AREA. AS IT IS… AM EXPECTING ISOLATED SHOWERS AND THUNDERSTORMS TO
DEVELOP SATURDAY MORNING WITHIN AREA OF WARM AIR/MOISTURE ADVECTION
AHEAD OF AN ILL-DEFINED COLD FRONT. THE FRONT SHOULD USHER IN
MORE WIDESPREAD CONVECTION DURING THE AFTERNOON AND EVENING. BASED
UPON THE SYSTEM DYNAMICS AND STEEP LAPSE RATES… THERE WILL BE A
LIMITED SEVERE THREAT… WITH HAIL AND WIND THE PRIMARY CONCERNS.”
So basically, there is a limited amount of moisture to fuel thunderstorms of severe intensity. As for the development of linear convection (aka a squall line), the cold front is unimpressive at best. Overall, there are several ingredients in place for a severe weather event. What’s not unusual is the absence of other important parameters.
More interesting and humorous is the typo (?) concerning fire weather conditions. Those conditions exists year round when dew points are low, there is an abundance of dormant vegetation that is dry, winds are strong enough to meet wind advisory criteria, and recent precipitation events have not soaked the ground and vegetation enough to prevent the initiation and spread of a grass or wild fire. I’m not sure if the same FD in discussing the fire weather potential considered this a deliberate typographical error, but the mention of the following gave me a much needed chuckle.
“THE EXPECTED WARMING TREND AND DRY SPELL FOR THE UPCOMING WEEK
CONTINUES TO LOOK LIKE A GO. FIRE DANGER WILL MOST CERTAINLY BE THE
HIGHLIGHT OF THE WEEK… WITH AVAILABLE FINE FUELS DRYING RAPIDLY.”
I’m assuming that the intended wording was to be “fire fuels drying rapidly” but with some fuels being better than others for fire weather conditions, I’m sure that describing some as “fine” is very appropriate.
Besides, what better way for a paranoid hermit to boast about his or her dilapidated double-wide being burnt to a crisp than to be gifted the opportunity to lose said abode to “fine” fuels.
