Data are everywhere.🌍 Effective visualizations are essential for making sense of complex information. This article examines how numerical weather models utilize grid resolution to estimate hurricane wind speeds, emphasizing how these models affect the accuracy of visualizations. Understanding these concepts can improve our knowledge of data modeling in weather forecasting. To see these in action, check out earth.nullschool.net and explore real-time weather visualizations.

🌪 A GIS Approach to Reveal Texas Tornadoes: Historical Occurrences and Impact Analysis 🌪 I’m excited to share my latest project analyzing tornado risks in Texas, Using historic data (1950-2022), I've mapped out tornado occurrence, frequency, and intensity across the state, identifying both urban and rural areas at risk. 🗺️ 🔍 Key findings include: Tornado frequency and risk zones, ranging from low (2-10 annually) to very high (200+). Tornado intensity analysis based on the EF-scale (EF0 to EF5). Impact on population centers and infrastructure, including airports and property loss. The project highlights critical insights into tornado threats in Texas, particularly within Tornado Alley, helping us better understand the risks and mitigate future damage. Check out my presentation for more details. #GIS #TexasTornadoes #DataAnalysis #RiskManagement #NaturalDisasters #TornadoResilience

It was a simple fact of Oklahoma life that we would be under the gun each spring and summer for possible random destruction, injury, or even death by monsters from the sky. There was nothing we could do—other than stay alert during “tornado season” and seek shelter on mere minutes’ notice, preferably below ground. Tornados can occur anywhere in the United States (even rarely in Alaska and Hawaii) but in some states more than others. In my early years on a farm in northern Oklahoma, it was widely believed our state was at the “crosshairs” of the infamous and uniquely American region known as Tornado Alley. In today’s linked CBS article, the meteorological data on the first map show our belief was grounded in fact: in 1951–85, the area of highest national incidence was more or less centered on Oklahoma City—about 100 miles south of my family’s small farm. In recent years, though, national news media have carried more and more reports of Oklahoma-sized storms occurring especially often in the southeastern states. Again, the reported data bear this out: In 1986–2020, portrayed on the article's second map, peak occurrence has shifted hundreds of miles to the southeast, centering now over Mississippi. What does this mean? Maybe that, regardless of where you live in America, you ought to keep an eye on the clouds.  

Now that's a unique weather forecasting method.

ML showing great promise at predicting hurricane landfalls! Kudos to my talented colleagues working on these forecasting models, including Dr's Rémi Lam & Amy McGovern quoted in this interactive NYT article. Much more to come on weather extremes, critical in the changing climate. https://lnkd.in/gYzp2D5k

Researchers at ETH Zurich have succeeded in detecting heavy precipitation events directly with GPS data. The results of their study could significantly improve meteorological monitoring and forecasting. ⛈️ In brief ■ A new study by researchers at ETH Zurich has shown that GPS data can be used to detect severe storm events. ■ They discovered that heavy rainfall and thunderstorms impact the signal-to-noise ratio. ■ These findings could one day not only make weather forecasts more accurate, but also support the early detection of extreme weather events.

This past weekend I was invited to speak at the Hidden Hallows Star Party on the May 10th Geomagentic Storm, also known as the “Mothers’ Day Superstorm” or the “Gannon Superstorm.” This was one of the stronger storms in the past few decades, and it allowed people all over the country to see the northern lights. For many, like me, it was their first time seeing them. In addition to covering how space weather events are observed and tracked, this presentation also covered some of the impacts from this superstorm. Space weather is a unique topic for emergency managers as it tends to be a rather misunderstood hazard for the public. If you ask a group of people to talk about the impacts associated with a tornado or wildfire, many have a quick response; we generally do a good job educating people on these hazards. With space weather, however, you get a whole spectrum of responses ranging from people not really aware of any implications of geomagnetic storms all the way to some people thinking that they could lead to the fall of mankind, which is probably not going to happen. Given that we are about to reach the peak of solar cycle 25, and that many of the strongest flares tend to take place soon after the peak of a given solar cycle, it is a great time to read up on the basics of space weather. Here is hoping that we get a few more opportunities to see the northern lights as this cycle progresses! (Perhaps sooner than later given today's solar flare activity)

Are you ready for the weather week ahead? 🌧 ☂ Tomorrow.io's meteorologists are consistently monitoring significant conditions across the U.S. on a weekly basis. Here's a snapshot: 🌧️ Southern California Flood Alert: Heavy rain is drenching Los Angeles and southern California, with 2-4" expected, escalating to 5-6" in mountain areas. Watch for swift-moving runoff causing localized flooding and urban street flooding. Rainfall should ease by tonight with more showers possible Wednesday and Thursday. 🌲 Northern California & Pacific Northwest: Coastal rain showers continue across northern California to southwestern Oregon, with 1-2" new rainfall anticipated. Northwestern Oregon and western Washington will also see light to moderate rain, with more expected Wednesday through the weekend. ❄️ Sierra Nevada & Intermountain West: Significant snowfall continues in the Lake Tahoe area, adding 1-2 feet through tonight. Expect 5-10" in Nevada's mountains and 6-12+" in Utah and Idaho's higher elevations, extending to Wyoming and Colorado. 🌨️ Northern US & Great Lakes: Mild early week conditions shift as a system brings snow across the Dakotas to NW Minnesota, with 6-10" possible. Lake-effect snow may impact Buffalo, Rochester, and Cleveland, causing potential blowing snow. ☀️ Central Plains: Anticipate snow around Denver with 3-6" expected, extending east into Nebraska and Kansas over the weekend, with lighter accumulations towards Kansas City and Omaha 🌩️ Southern US & Ohio Valley: Above-normal temperatures and breezy conditions set the stage for showers and potential thunderstorms across the Midwest, moving into the Ohio Valley with a chance for severe weather due to unseasonable warmth. 🌀 Southeast Thunderstorm Watch: The weekend will see rain and thunderstorms across the lower Mississippi Valley to the Southeast, with 1-3"+ rainfall expected from Houston to Atlanta, though severe storm potential remains limited. 🌤️ Mid-Atlantic & Northeast Calm: A quiet week with cool, sunny days ahead for the Mid-Atlantic. Minimal snow showers expected in coastal Massachusetts, with light rain arriving by the weekend and extending into the Northeast.
