Merry Christmas! (44% of the USA has snow on the ground – above average)
Your Big Gift
I’m stepping off the consumerism-treadmill this year. Why? More megapixels and gigabytes won’t make me any happier; technology that’s obsolete when I walk out of the store.
In the end all this “stuff” won’t matter much. The magic of Christmas? The most precious gifts are staring us in the face: the hustle & bustle of gloriously inconvenient friends & family camped out under the tree.
No ties, socks or shiny-red Dopplers this year. Experiences trump things. Turn off your Facebook and surprise me with some face-time. Quality time with your (real) social network is the biggest gift of all.
Although, come to think of it, monogrammed snowshoes might make a lovely gift this year.
Christmas Conjunction In Space. Was the Star of Bethlehem a conjunction of planets? Interesting timing with a new conjunction visible, this one from a satellite on the other side of the sun, as reported by spaceweather.com: “According to some scholars, the Star of Bethlehem might have been a close encounter between Venus and Jupiter. The two brightest planets in the night sky, merged, would have made a spectacle of Biblical proportions. This Christmas, NASA’s STEREO-B probe is observing a conjunction of three planets–Venus, Earth and Jupiter...”
Snowier Than Average Christmas Day. The 10-year average for percentage of the Lower 48 states with 1″ or more of snow on the ground is 39% This year: closer to 44% It would have been higher but last weekend’s freak, solstice storm pulled record warmth unusually far north, melting a lot of snow. In today’s Climate Matters we take a look at December temperatures around the USA, and which parts of the nation are ending with a moisture surplus or deficit: “WeatherNationTV Chief Meteorologist Paul Douglas shows just how low the mercury dipped in the northern states early Christmas Eve morning. And on the eastern seaboard they saw record highs? Talk about weather whiplash. How much of the United States will see a white Christmas? Turns out we’re above average. The west is seeing one of its driest years on record while the eastern half of the nation is getting soaking rains. Merry Christmas!“

NASA Builds GPS-Based System For Detecting Natural Disasters. It’s all about the resolution and timeliness (latency) of raw data, and what you do with it. Here’s a clip fromallvoices.com: “…Forecasters at NOAA National Weather Service offices in Oxnard and San Diego, California demonstrated the new technology in July, using it to track a summer monsoon rain affecting Southern California and issue more accurate and timely flash flood warnings. The new technology uses real-time information from GPS stations that have been upgraded with small, inexpensive seismic and meteorological sensors. Other real-world systems are integrating the new technology as well. For example, it is being used to make damage assessments for hospitals, bridges and other critical infrastructure that can be used in real time by emergency personnel, decision makers and first responders to help mitigate threats to public safety...”
Heavy Pollution Enshrouds Northern China Including Capital. Bloomberg has an update on the record levels of smog gripping China – here’s the intro to a recent story: “Heavy pollution enveloped northern and central China today, prompting warnings for people to stay indoors as smog levels in some areas exceeded World Health Organization-recommended levels by 30 times. The concentration of PM2.5, fine air particulates that pose the greatest health risk, was 421 micrograms per cubic meter at 2 p.m. near Tiananmen Square in Beijing, compared with an average of 228 over the past 24 hours, the Beijing Municipal Environmental Monitoring Center said on its website. Levels of PM2.5 hit 795 in Xi’an and 740 in Zhengzhou. The WHO recommends 24-hour exposure to PM2.5 concentrations no higher than 25 micrograms per cubic meter…”

The 5 Top U.S. Weather Stories Of 2013. Here’s an excerpt of a list compiled by The Capital Weather Gang that (in my humble opinion) has the right idea: “In the United States, the major weather stories of 2013 are somewhat contradictory. One the one hand, several horrible weather events occurred, from violent tornadoes in Oklahoma to record wildfires in the West to “biblical flooding” in Colorado. But the year also brought the fewest tornadoes in recent memory and a largely absent Atlantic hurricane season. Overall, 2013 is likely to finish with 8 billion dollar weather disasters in the U.S., down from 11 in 2012 and 13 in 2011 but up from the 4 in 2010 and 6 in 2009. Here are my selections for 5 biggest weather events of 2013 in the United States, presented in no particular order…”

Dried Up And Maxed Out – California Tries To Make It Snow. 2013 has been the driest year on record for the state of California. Will cloud seeding help to squeeze out a few more inches over the Sierra Nevada? Governing.com has an interesting article; here’s an excerpt: “…Cloud seeding has been around for almost 70 years now, since Vincent Schaefer, a self-taught chemist, dumped six pounds of dry ice into the clouds over the Berkshire Mountains in Massachusetts in 1946, making them snow. The experiment led to speculation that cloud seeding could fight drought, control storms, reduce hail and quench forest fires. Indeed, today about 10 states, mostly in the West, have cloud-seeding operations to combat such conditions. In Arizona, California, Colorado, Idaho, Nevada, Utah and Wyoming, cloud-seeders are hired to increase the snowpack. In Kansas and Texas, they work to induce rain, and in North Dakota, they induce rain before the clouds can produce crop-damaging hail…”

A Moonlit Shield Of Clouds, As Seen From Space. Here’s a snippet of an interesting image and explanation from discovermagazine.com: “On Dec. 18th, 2013, an almost full moon enabled the Suomi NPP satellite to capture this unusual visible-light image of a spectacular cloud formation along the eastern slope of the Rocky Mountains in Colorado and Wyoming. You can tell it’s nighttime from the points of light that are most clearly visible in the right portion of the image. These are towns out on the high plains of Nebraska and Kansas. The white stuff that seems to streak off the mountaintops comprise what’s known as orographic cirrus clouds…”

Snow: Every Budgeters Worst Nightmare. Keeping roads clear of snow and ice is non-trivial, and expensive. Here’s a clip from an article at Governing Magazine: “…Predicting just how much a local government will need to spend for the upcoming winter is only a best guess. Costs vary widely from year to year, depending not only on the severity of the weather, but where on the calendar storms fall and even the time of day a storm hits. The city of Minneapolis attempts to project its snow and ice removal costs by looking at averages over the previous three to five years. For fiscal year 2013, the city budgeted about $10 million. In recent years, though, the total bill has ranged from slightly more than $7 million all the way up to $12 million. “We try and budget for an average year,” says Deputy Public Works Director Heidi Hamilton. “But there’s never an average year...” (photo credit: Jessica Hill, AP).
Weather Effects On The Patterns Of People’s Everyday Activities: A Study Using GPS-Traces Of Mobile Phone Users. Hey, you could have just asked the NSA, right? Here’s a clip from an interesting study that uses cellular data to track how changes in weather affect our behavior and movement – derived from the records of 31,855 mobile phone users, courtesy of PLOS ONE: “…Our analysis of 31,855 mobile phone users allowed us to infer that people were more likely to stay longer at eateries or food outlets, and (to a lesser degree) at retail or shopping areas when the weather is very cold or when conditions are calm (non-windy). When compared to people’s regular activity patterns, certain weather conditions affected people’s movements and activities noticeably at different times of the day. On cold days, people’s activities were found to be more diverse especially after 10AM, showing greatest variations between 2PM and 6PM. A similar trend is observed between 10AM and midnight on rainy days, with people’s activities found to be most diverse on days with heaviest rainfalls or on days when the wind speed was stronger than 4 km/h, especially between 10AM–1AM….”
Americans Are Buying Less Electricity. That’s A Big Problem For Utilities. Here’s a clip from an article at The Washington Post: “Something very unusual has been happening to the U.S. electricity sector over the past three years. The U.S. economy keeps growing. People are buying bigger homes and plugging in ever more electronic gadgets. And yet power companies have been selling less and less electricity since 2011. That may not look like a particularly steep drop, but it’s a massive break from the past. Ever since World War II, electricity sales in the United States have, for the most part, gone up and up and up…”
Concept Cars That Could Change Transportation As We Know It. Gizmag has an intriguing article about how we may be getting around in the not-too-distant future; here’s an excerpt: “The average concept car experiments with styling, technology and packaging to explore potential new ideas. Some concept cars take it a few steps further, not just rethinking the car but redefining what a car is and exploring ideas that could completely revolutionize the way we get from point A to point B. From vehicles that drive themselves, to cars that fly and fold, some of 2013’s most interesting concept cars provided a lens into a very different future…”

- Welcome to my weather blog. Every day I sift through hundreds of stories, maps, graphics and meteorological web sites, trying to capture some of the most interesting weather nuggets, the stories behind the forecast. I’ll link to stories and share some of the web sites I use. I’m still passionate about the weather, have been ever since Tropical Storm Agnes flooded my home in Lancaster, PA in 1972. I’ve started 5 weather-related companies. “EarthWatch” created the world’s first 3-D weather graphics for TV stations – Steven Spielberg used our software in “Jurassic Park” and “Twister”. My last company, “Digital Cyclone”, personalized weather for cell phones. “My-Cast” was launched in 2001 and is still going strong on iPhone, Android and Blackberry. I sold DCI to Garmin in 2007 so I could focus on my latest venture: WeatherNation.
