Matthew Puts This Vantage Vue Down, But Not Out

When Hurricane Matthew had finally passed over Charles Huck's home in South Ponte Vedra Beach, Florida, in October, Charles ventured out to assess the damage. He found an old friend, down, but far from done. His Vantage Vue was ripped from her mount, floated off on the storm surge, and dumped back on the beach, where Charles found her lying in the weeds. The wind speed shaft was too bent to work, and she was full of sand and seawater, but after a little TLC, the temperature, humidity, wind direction, and rain gauge were all quickly back in working condition.

Hey, when we say we built that thing to be tough, we meant it. Thanks Charles!

AnemometerWeather Check Quiz Question 1:

Hurricane Matthew, was a Category 5 (the highest on the Saffir-Simpson Wind Scale) hurricane that formed in the Atlantic in September and October. A Category 5 storm is not, unfortunately, that rare. There have been 34 Category 5 hurricanes in the Atlantic since 1924, and three of those even made landfall in the US as a Category 5. (Unlike Matthew. By the time Matthew made landfall in the US, after battering the Caribbean, it was downgraded to a Category 1.)

But Matthew was the first of its kind anyway. How was it a first?

Extra Credit True or False: Hurricane Matthew was typical in that the worst damage was caused by high winds.

Chasing Storms in the Netherlands

We can NOT get enough of this fantastic video made by our Dutch resellers Wittich & Visser of their storm chasing team known as Vortex 1!

It's not just that the leading lady is our Vantage Vue, it's also that it's jam-packed with gorgeous images set to a perfect soundtrack -- the whole artsy-meets-techy vibe that makes us want to just get out there in the baddest weather!

You need to watch this video 5 or 30 times TODAY.


These Vantage Vues Have Tiny Modular Homes

Creative Backstage, an award-winning production company that specializes in lighting, sound, video, staging and more, knows that for outdoor events, you can never be too safe. They always pack up their little, but mighty, weather stations when setting up an outdoor venue. Vantage Vue's size makes that easy to do!

They wrote,"We do not mess around with weather. Weather is a must for outdoor stages. The Vantage Vue is the number-one piece of gear we have when it comes to outdoor events we do. Works so great I got one for my house which is linked to Weather Underground."

Rock on Vantage Vue!

Vantage Vue at the End of the Rainbow in Australia

Phillip Riedel, you know how to take a photograph of a weather station! First, you get a really handsome one then you put it on a rooftop in beautiful Thebarton, Adelaide, Australia. Then you get a perfect double rainbow and have it position itself in the background. Then snap a nice panoramic photo!

Philip is the guy who gave his name to his company, Riedel Surveillance.

"We are a specialist remote CCTV surveillance company and have interfaced the Davis weather stations with Mobotix cameras from Germany in a number of sites," he told us. "The camera can just be seen in the top right corner of this photo"

AnemometerWeather Check Quiz Question 2:

True or False:
The colors are reversed in the second arc of a double rainbow.

Extra Credit: You're at a party and mention that you just saw a double rainbow!

A big arrogant fellow sniffs and loudly proclaims, "My dear, double rainbows are quite common. I myself have seen supernumerary rainbows, which are quite different. You see, I have traveled extensively and have seen fogbows, 360-degree bows, waterfall bows, blood red bows, Alexander's Band, cloud rainbows, snowbows, rainbow wheels, lunar rainbows, upside down rainbows, even the rare twinned rainbow."

You shout, "Fraud!! One of those does not exist!"

Which one?

AnemometerWEATHER 101

What the Hail is Hail?

Back in 2014, we told you about a big hail storm that hit Foster Byrd's neighborhood in Denton, Texas. Things haven't calmed down much for the folks in Denton. In the spring of 2016, there were 13 hail reports within 10 miles of Denton, with one storm dropping 4" balls of ice. Foster's Vantage Pro2, however, laughs at the mere bullets of ice bouncing around it.

Foster wrote to tell us that he finally got around to inspecting his Vantage Pro2 when his son-in-law climbed up the ladder to the roof and brought it down.

"I cleaned out the rain gauge," he wrote, "changed out the back-up battery, and made careful examination of the components for signs of damage from hair-line cracks to chips or dents and found none. I was amazed that nothing was damaged anywhere on the unit (unlike our pickups which received a few hail dings in the most recent storm).  Again it was either very lucky or very well designed...I prefer to think it is a great deal of both since it has seen almost seven years of Texas extremes and continues functioning beyond my expectations.  It has never been turned off this entire period of operation.  It is mind-boggling just to do the math on the number of transmissions the sensor suite has completed in this length of time. If only my personal computers had exhibited so few issues during that same time!"

Vantage Pro2s, like all our weather stations are designed to withstand the elements. And of all the elements, hail can be among the hardest to withstand.

Hailstones are pieces of ice, often round, but sometimes irregular in shape, that form when ice particles are swept up horizontally into a cloud by a tilted updraft. On the way, they pass through areas of higher humidity and collect supercooled droplets which coat and freeze to them. When they get heavy enough, they fall to the ground, denting cars and bruising heads.

Hailstones in cross section have a layered nature. Cut one in half and you see will see thick translucent layers between thin opaque layers. Meteorologists used to think the layers were caused by the stone making repeated trips up into the cloud, collecting supercooled droplets, then falling, which caused the surface to melt a bit, before it is swept up again and the liquid on the surface refreezes in an opaque layer. Current thought now is that stones don't necessarily make repeated up and down trips. Rather, they are swept up into the cloud, traveling through higher and lower humidity zones and gathering icy layers in different amounts depending on the humidity and the presence of supercooled droplets in each zone. As it gets heavier, the stone falls and gathers even more ice on the way down.

Hail is dangerous: it can damage vehicles, break windows, and wreak havoc on livestock and crops. Quite a few farmers have stood in outbuildings and watched a single hailstorm destroy their entire crop in a matter of minutes. That's why farmers call hail storms "The White Plague."

We remember a certain road trip in western Texas, when everyone on the highway around us stopped under an underpass. Why would they do that? we wondered as we whizzed past them. Minutes later our little blue car was pocked life a golf ball. (And being baby Weather Nerds, we rather liked it that way!)

AnemometerWeather Check Quiz Question 3:

Has anyone ever been killed by a hailstone?

Extra Credit: Are hailstones the same as sleet?

Extra Extra Credit: Everybody (farmers excepted) love a nice little hailstorm. What's not to love? The sound! The white stuff puddling on the ground! The pool looking like it is suddenly boiling! If you really, really, really loved hail, which of these places would be the best place to live?

  • Zacatecas, Mexico
  • Cheyenne, Wyoming, United States
  • Kericho Hills, Kenya
  • Selfoss, Iceland
  • Wollongong, New South Wales, Australia

Anemometer I Spy a Davis Station

Spied at the Malmö Arena in Sweden

Sensifarm installed this Vantage Pro2 at Sweden's Malmö Arena. The arena is the home of the SHL ice hockey team, the Redhawks, and Swedes love a good hockey game! Apparently, they love Lady Gaga a little more. She drew the attendance-record breaking crowd of 11,300.

And The Vantage Pro2 gets to see it all!


Spied in the British Countryside

Jason Want was out of commission for a while and unable to ride his bike. So he used his time wisely and relocated his Vantage Pro2 at his new house near Helston, Cornwall in the United Kingdom. Jason is proud to call himself a Weather Geek! We call him a Weather Geek with the eye of an artist!

Spied on the La Pointe St. Mathieu Lighthouse

Daniel Sylvestre was strolling the Brittany coast near Le Conquet in France. He was there to take photos of the 180-year-old lighthouse when he noticed a bit of modern technology in the form of a Vantage Pro2!

"I was surprised", Daniel told us, "to see that a Davis Vantage Pro2 was used by the techs of the Phares et Balises (Lighthouses and Beacons) institution to perform weather measurements. Notice the Yagi antenna which I suppose is used to transmit data to a specific supervision center, located on the nearby isle of Ouessant, processing and making it available to concerned people. Here are a few photos of the station. The weather was not fine on that day...

"This part of Brittany is submitted to very harsh weather conditions. Close to the lighthouse, there is a French Navy's semaphore supervising the Ouessant track ship traffic. The area between the isle of Ouessant and La pointe Saint-Mathieu is well-known to be a difficult place to sail because of numerous rocks all around and powerful streams putting sailors at risk. The site is also known for the ruins of a magnificent Abbey founded in the 6th century."

AnemometerWeather Check Quiz Question 5:

In the early days of the medieval Abbey de St. Matthieu, the monks built fires to prevent shipwrecks. Which didn't really always work. But some of the monks, who surely felt very bad and prayed for the souls of drowned sailors, might have been just a little bit happy. Why? (Pick one!)

  1. A pervasive belief that St. Marcel, the patron saint of sailors, hated St. Matthieu.
  2. They were entitled to a cut of the salvage, and used that money kept the fire burning and the monastery going.
  3. They often enlisted new monks among the men they saved from shipwrecks.
  4. Sea captains often donated to the monastery, believing the prayers of the monks would protect them. An occasional shipwreck was good incentive to keep this practice alive.

Question 1: Hurricane Matthew was the first of its kind?

According to Colorado State University tropical scientist, Dr. Phil Klotzbach, Matthew became the lowest latitude Category 5 hurricane in the Atlantic on record (beating the old record set by Ivan in 2004).

Extra Credit True or False: Hurricane Matthew was typical in that the worst damage was caused by high winds.

False. What does the most damage in most hurricanes is storm surge and flooding. Dennis M. Swanson's Vantage Pro2 in Hunter's Run, North Carolina recorded 12.37 inches of rain during 12 hours of Matthew's little visit to his neighborhood. NOAA reported 17.5 inches in Savannah, Georgia, and over 15 inches in several place in North Carolina. There were highways flooded and closed in North Carolina, and several feet of water in Raleigh. Cars, town halls, and houses were flooded in South Carolina.

Question 2:True or False: The colors are reversed in the second arc of a double rainbow.

True! They are also fainter than the primary arc.

Extra Credit: You shout, "Fraud!! One of those does not exist!" Which one?

No such thing as a snow-only rainbow! Bet you thought it was Alexander's Band, right? That's the band between the two arcs of a double rainbow that looks dark. Here are some fun click-throughs to see pretty photos of all kinds of rainbows: Scientific American sand 10 Beautiful Types of Rainbows.

Question 3: Has anyone ever been killed by a hailstone?

You bet. In one horrible storm in India in 1996, 92 people were killed. According to Daniel Engler of Slate, hailstones have killed a handful of people in the United States over the last 100 years.

Extra Credit: Are hailstones the same as sleet?

Nope. Sleet is a cold weather phenomenon. Hail doesn't usually form when surface temperatures are too cold.

Extra Extra Credit: If you really, really, really loved hail, which of these places would be the best place to live?

Kericho Hills, Kenya. Yep. Kenya. They have hailstorms about 132 days a year. Makes Cheyenne's measly 10 look boring. But if you want to stay in the U.S., Cheyenne or any place in Hail Alley (Texas, Oklahoma, Colorado, Kansas, Nebraska and Wyoming) would be a good bet. In Hail Alley, the warm moist air coming up from the Gulf of Mexico runs smack dab into cold dry air coming down from Canada and, voila, hail!

Question 4: Is this a good time of year to clean and maintain your weather station?

Yes, because it's always a good time to clean your weather station!

Question 5: Some of the monks might have been just a little bit happy. Why? (Pick one!)

2. They got to take 10% of the hull, cargo and rigging of any wrecked ships.
