VORTEX2: June 9, 2009 - 30 days. Operations provided for in the field: spectacular supercell.
Miles traveled today: 403. Miles traveled total: 10,107 .
The awakening comes with a thunderstorm and the noise of small hailstones on the roof. For the day we have a front Hot on the border between Oklahoma and Kansas in a slow climb to the north and west by Dryline the triple point in the south-western Kansas.
Convection morning led to the formation of a Mesoscale Convective System over the northern part of Kansas boudary producing an outflow that will go 'progress towards the south during the day. The ingredients are all good for today, finally humidity 'has invaded the Plains and the presence of low pressure at high altitude in the western part of the United States provides a strong southwest flow at high altitude. Leaving Salina
in late morning lunch at one o'clock and thirty Newton and leave the parking lot for a track that has almost reached the CAPE 4000 J / Kg and we are approaching the line of piles that has' developed just south of our position in the direction of Wichita. The Convention will be structured today
'certainly one of the convergence dell'outflow boudary proviente from the north and the warm front in the south slope.
Winds from the north-eastern boundary will make the present behind the warm front and this will almost stationary 'means that in practice the supercells will move along the line of convergence from west to east. We are positioned to the west of Wichita.
The piles were formed but still struggling to grow, to 14.30 Tornado Watch is issued with a probability 'of 70% have two or more' tornado and move even more 'west to Pratt.
Unfortunately the best shear and humidity 'more' are high in the east of Interstate 35 but the presence of many hills and a road network not conducive to the operations of VORTEX2 prevents us from going in that area.
Dryline the West is moving from the West Texas Panhandle and Kansas and with the slow progress towards the south of the boundary there could be an area of \u200b\u200bhigh and moderate CAPE shaer just north of the front.
At 4:45 after the fuel stop in Pratt and while all the chasers are concentrated around the Wichita area, comes a new target Mullinville west of Greensburg, as little to the west of Dodge City and 'formed an isolated cell.
Initially the storm develops slowly to the west of the city 'and then at 6 pm eplodere once passed north of the city '.
At the time radar images is divided into two cells and during the hour and a half later
what is happening and 'textbook of meteorology. From the splitting of the cell form two supercells a cyclonic (the south) and a cyclonic (northern) and as a script that 'most southerly takes strength and the northern set of intensity'. The armada
goes on southern supercell begins to show characteristics of both the beautiful with a radar hook echo textbook is visually. The probes are guided along with nell'inflow DOW6 and here we witness a magnificent spectacle.
mesociclone The rotating 'in front of our eyes and we have a good ten minutes to see it moving further 'vertical wall with its sharply sculpted, I think it's the best I've ever seen so mesociclone' closely.
Then when the RFD reaches us we should leave the position just in time 'cause the sky begin to fall sparse hailstones the size of golf balls. Via radio once again one of the NSSL probes, this time the number 8, is damaged by the breaking of the windshield due to hail the size of baseballs. There appears to take pleasure in destroying their car.
We report our vehicles on Highway 400 while the supercell remains perfect at the radar, while moving nell'outflow see some gustnado. When Greenburg we arrive again in the vicinity 'of mesociclone that even if he lost a bit in the last minute' intensity 'to the radar is still showing extremely photogenic sight.
Suddenly the DOW 7 indicates an increase in the rotation in the lower layers of dust and lifts the base of the wall cloud, this is another vortex on the edge of the gust front but at the same time is given by of a storm-chaser a brief touchdown of a tornado about four miles west-northwest of Greensburg is difficult but nevertheless finding confirms the potential 'of the supercell.
Between seven and eight in the evening with the manufacture of mesonet transects for data collection on the ground within dual-Doppler lobe of the Doppler On Wheel 6 and 7. At eight was declared an end to operations in this day which saw most of the emotions concentrated in a few hours. From the scientific point of view and 'was another success and what' was documenting the entire life cycle of the supercell.
While we'll be musical means to Wichita for the night we have a chance 'to verify the reports of the day on the website of the Storm Prediction Center. They are certainly a few, that do not justify a Moderate Risk Watch and a Tornado with those percentages ... The project
VORTEX2 though the season can be classified as one of the most 'failure of ultmi year is still proving such as coordination and research to reach levels of complexity 'very high allowing all teams to collect a quantity' of data on different types of huge storms, supercellulari and which will provide scientists and students study material and labor many years to come.
