VORTEX2 Summary

Preliminary numbers show VORTEX2 intercepted about 30 supercells, and 20 weak or short-lived tornadoes.

13 June 2010

Hotel location:  Liberal, KS Intercept location:  Booker, TX Data was collected on a long-lived tornadic supercell that developed in the northeastern Texas Panhandle and moved into the Oklahoma Panhandle.  At least three tornadoes are known to have occurred within this storm.  The first was the most significant and had the best data collection with mobile […]

Hotel location:  Chadron, NE Intercept location:  Last Chance, CO Two supercells were intercepted.  The first was non-tornadic but was sampled well by the mobile mesonet. Second cell formed south.  A tornado was observed for 8 minutes, but data collection was hampered by lack of roads.  A second tornado occurred shortly after for 5 minutes.  Dual-Doppler […]

Hotel location:  Ft. Morgan, CO Intercept location:  Scottsbluff/Mitchell, NE Two tornadic supercells in the Nebraska panhandle.  The first increased in speed and moved out of reach of the VORTEX2 array except for Sticknet.  A tornado was produced just east of the Sticknet, and was observed from a distance both by SMART radars and DOW6. Two […]

Hotel location:  Loveland, CO Intercept location:  Tribune, KS VORTEX2 deployed on a cyclic, weakly tornadic supercell in western Kansas.  Among the test cases sampled in VORTEX2 given the simultaneous collection of storm-scale and mesocyclone-scale dual-Doppler radar observations, along with in-situ measurements.  The target storm emerged from a cluster of storms that developed along the KS-CO […]

Hotel location:  Amarillo, TX Intercept location: Dumas, TX VORTEX2 intercepted a long-lived supercell in the northern Texas panhandle that developed along a dryline.  The storm produced a number of weak tornadoes.  Mobile mesonets reported good data collection within dual-Doppler coverage, and were able to sample the storm’s outflow and inflow.  The TTU Ka-Band radar had […]

Morning location:  Weatherford, OK Intercept location:  Clinton, OK VORTEX2 intercepted a high-precipitation supercell in southwest Oklahoma the developed along a dryline.  Storms were moving at 30-35mph to the northeast.  A tornado developed near the northeast edge of dual-Doppler coverage and reportedly crossed I-40 just east of Clinton.  Mobile mesonets and dual-Doppler data were collected for […]

10 May 2010

Hotel location:  Perry, OK Intercept location:  Seminole, OK An outbreak of tornadoes occurred in central and eastern OK.  Supercell motions were very fast, ranging from 50-60mph.  Given the fast motions, it was believed that the best opportunity for useful scientific data collection would be by forming a fixed radar network with six of the mobile […]

5 June 2009

Hotel location:  Sterling, CO Intercept location:  La Grange, WY VORTEX2 targeted a right-moving supercell that formed north of Cheyenne, WY. An X-Band radar was sampling the storm as mobile mesonets took measurements within the hook echo and tornado cyclone.  All radars were deployed at the time of tornadogenesis, and valuable dual-Doppler data was collected.  Sticknets, […]

10.26.10: A different approach to the V2 best cases report

I decided to take a different approach to discussing the VORTEX2 best cases. I will discuss them by day. Read on to find out why!
