![]() ![]() Severe thunderstorms are more likely when the surface dewpoint is 55 F or higher, all else being equal. Low level moisture is assessed by examining boundary layer dewpoints. Evaporation is higher in warm ocean currents and therefore they put more moisture into the atmosphere than with cold ocean currents at the same latitude.ĭetailed Explanation from Water temperature also plays a large role in how much moisture is in the atmosphere. Typical sources of moisture are large bodies of water such as the Atlantic and Pacific oceans, as well as the Gulf of Mexico. you can see images from the latest GOES-16 satelliteĪll thunderstorms require three main ingredients with a fourth also mentioned: Mositure, Instability and Lift are the main ingredients along with wind shear. Skip’s viewer for Earl’s 3km CAPE and LSI plots:ĬOD Satellite (1km Products -> Visible shown) The details of storm chasing and meteorology can be seen at this website Ī good presentation from a great storm chaser Ĭollege of DuPage numerical forecast models – this is what the media sees from the national weather service Stormtrack – a website for storm chasers to talk about forecasting, etc. Tornadoes website has a wealth of Tornado knowledge Tornado Titans Website has a lot of good information They are the red dots you see in my radarscope screenshots. To be able to see other storm chaser positions, sign up for Spotter Network. On my Computer I use GRLevel 3 & SHARPpy for Sounding / Hodograph Analysis Understanding Basic Tornadic Radar Signatures ![]() ![]() SPC’s Convective Outlooks, these help you plan a few days in advance the details of a possible storm chase. I have the Pro edition as well as a monthly subscription to Allison House so I have high quality and current data feeds, often just a minute or few minutes old compared to weather channel which can be 30 minutes old at times, I enter in my login details into radarscope as well as placefiles in GRLevel 3. Radarscope On phone for chasers and basic public (they even have it for mac computers) Storm chasing is a lot of fun, but it can be intense and involves a lot of multi-tasking and being tech savy is important. What the red & green colors are actually telling usĭo you ever jump back and forth between reflectivity and velocity data on an interesting storm? Now you don‘t have to.What does this mean and why should you know? Super Res Reflectivityĭoppler radar data can show if a storm is rotating. What is reflectivity really showing us and should you be concerned when you see scary colors? Data varies for storms at different distances.Join us as we discuss how the location of the radar beam shows us different data than you might think. Radar works very similarly to a flashlight. Once you have the app installed, it is important to learn what all the radar types and colors actually mean. Most storm chasers use Radarscope, some use it for solely on the chase and others use it to supplement other programs such GRLevel3. Storm Spotting as it is officially called with the National Weather Service is important I think for everyone to have some education even if you don’t want to know the advanced level. At the advance side so you can storm chase too. I wanted to share the tools so at the very basic level you can be educated on storms. When I realize what the general public sees as well as what I saw growing up and now what I see. I’m a “noob” as people call themselves in the chasing community. I’ve been chasing now for 3 years, each storm and year learning more and more. I found chasers are everywhere, hundreds if not thousands of us across the world. It occurred to me that I could learn the skills and save a lot of money and chase myself or with other chasers. It wasn’t 2013 while watching “Storm Chasers” on Discovery channel that it occurred that other people liked to chase after storms and paid $2,500 for a week trip on Extreme Tornado Tours on the Great Plains. ![]() I couldn’t tell you the difference between a shelf and wall cloud for many years but it was just awe-inspiring to watch the sky turn almost black where I lived in Ohio for an approaching supercell. Throughout all the years I would get in the car with a camera and follow the red square for any Tornado warned storm, having no clue what I was looking for beyond something interesting I could photograph at the great holy grail, a tornado. I was often scolded by my mom for being outside when storms were approaching as I watched. I have always been interested in weather, even at 8 years old I was a kid amateur meteorologist for a local TV station in Ohio and reported the weather of that day to them for my little town. Storm chasing, when most sane people go indoors and anxiously look at the tv or radar on the phone, us storm chasers will drive thousands of miles in hopes of seeing a tornado. ![]()
