A Preliminary Analysis of the May 16, 2017 Elk City, OK Tornado

Image

On 16 May 2017, one Doppler on Wheels mobile radar and one mobile mesonet observed the passage of a rain-wrapped tornado embedded in a high-precipitation supercell as it passed through southern Elk City, OK. The tornado, which preliminary estimates place at an EF-2, created a damage path from just south of Sayre and on through southern Elk City, before dissipating just short of Canute, OK.

TWIRL 2017 (aka tiny TWIRL) is here! From May through June 2017, CSWR staff and crew will be traversing the Great Plains, following severe weather potential in search of tornadic supercells. The project has already gotten off to a great start. Tornadoes have been observed in Texas and Oklahoma, including the McLean, TX tornado (right) and the Elk City, OK tornado on May 16. Follow us on Facebook and Twitter (@CSWRDOW) for more updates!

SNOWIE: Seeded and Natural Orographic Wintertime Clouds, the Idaho Experiment

CSWR has just completed the field phase of its participation in the SNOWIE project, which occurred from January to March 2017. DOW6 and DOW7 were deployed to the tops of two mountains in central Idaho, where they observed the dynamical and microphysical processes inherent to winter mountain precipitation.

SNOWIE seeks to understand how cloud seeding with silver iodide (AgI) modifies the amount and distribution of snowfall in mountainous terrain. The Idaho Power Company already maintains an operational cloud seeding program in the region using both aircraft and ground generators. During a cloud seeding event, silver iodide is released directly into winter storms, with the hope that snowfall totals are ultimately increased. The increase in snowfall benefits both agriculture and hydroelectric power generation by increasing spring snowmelt. The DOWs, together with the University of Wyoming King Air research aircraft, took observations of the AgI plume during cloud seeding events to determing their effectiveness. The project was a joint effort between researchers from three different universities, the National Science Foundation, the National Centers for Atmospheric Research, and the Idaho Power Company.

The Doppler on Wheels Network

Image The Center for Severe Weather Research (CSWR) operates the Doppler on Wheels (DOW) mobile radar network, consisting of two dual-polarization, dual-frequency mobile radars and one multi-beam, rapid scan radar, as a National Science Foundation (NSF) facility. Researchers and faculty can request the DOWs for their projects.
