Mips Mobile Integrated Profiling System

3. MIPS - Mobile Integrated Profiling System Microwave Profiling Radiometer Doppler sodar 915 MHz Doppler Profiler Lidar ceilometer Surface instrumentation 18 June 2002 Deployment 3 IR radiometer

18. MIPS MGLASS1 MGLASS2 Notes: Distance between MGLASS1/2 = 50-200 km, MIPS located in between. Sounding release time interval: 1-1.5 h Need knowledge of storm & MCS motion vector, boundary movement tendency. Scaled baseline 100 - 200 km MP 40-50 km leg Period of ~1 h Linear Array Pre-storm environment (CBL to NBL) boundary Storm motion Developing LLJ ~3 h

19. MIPS MGLASS1 MGLASS2 MP Sampling of Bow Echo convective region (NBL most common) Scaled baseline 100 -200 km Notes: MP is stationary and ~5 km up-track. Will sample strength of storm and potential severe attributes such as hail. Sounding launch within, or just in advance of convective updraft. LLJ Desired sounding locations

20. MIPS MGLASS1 MGLASS2 100 - 200 km MM Sampling of Bow Echo stratiform region (NBL most common) Notes: MP transects 50 km long within stratiform region. LLJ Soundings at different times in critical locations: - Cold pool behind the line - Just in advance of the line - Within St region - Within conv updraft - Core of comma or incip. MCV - After ppn within wake low and upper RIJ

21. MP MGLASS1 MGLASS2 Environment in advance of MCV (CBL) 100 km Notes: Soundings downshear (900-600 mb) of MCV center, in region where CI is most likely. MP will work boundaries, and/or region of potential CI. Triangle in downshear sector of MCV (triangular shape for w estimation). GBOS will deploy ~2 h in advance of the MCV. Will depend partly on aircraft operations since GBOS will attempt to coordinate with aircraft. LLJ V shear V mcv Triangle size 75-150 km Soundings: simultaneous, w most important in 900-600 mb MIPS Flexibility! Design dependent on 403 MHz profilers and 88D MP may be within triangle and located further S in this case. Parent MCS outflow boundary

22. MP MIPS MGLASS1 MGLASS2 Measurements within/near of MCV Notes: MGLASS-1 and MGLASS-2 redeploy downtrack if possible. MIPS would redeploy after vortex and precipitation passes over. Would take 1.5-2 h to move to the front of the MCV, assuming 100 km / 20 m/s. If the MCV is moving 10 m/s, then sampling lasts 100 km / 10 m/s = 10 4 s. Total duration of 2 sampling periods + one redeploy equals about 8-10 h. Potential redeployment on MCS that develops with/around MCV. 100 km LLJ

23. Large MCS deployment (NBL most common) M-GLASS1 M-GLASS2 MIPS MM 100 km Notes: Length of deployment? 300 km / 20 m s-1 = 15,000 s ~ 4 h MCS motion wind Excessive rain
