11 July 2004 0013 Rit and Steve leave. They thought about switching to climo PRF at the top of the hour in the middle of a microphysics routine 0151 Now they simply want to explore the 710-720Hz PRF. What vertical resolution can be achieved at 30, 60km? 710hz/100 X 0.8 = 5.68degrees/sec. 0253 Tim is here and in charge 0300 Running climofar to 15degrees 0332 Scattered convection continues with climofar synching OK. 0358 Prof Scans: PPIX4 RHIX4 Rain Map PPI 3 tilts 0.5 - 1.5 width 42 center 331 Rate 4degree/sec 200 samples - change to 140 pulses RHIs 3 tilts 330-332 Rate 3degree/sec 200 smaples - 190 pulses to accomodate running low or high PRF 0-30 degree elevation 0415 Created new low PRF climo scans, designed for 720Hz. 14 tilts fit in 15 min, so have 13 reg tilts and a 0.0 seas-breeze. CLimonear, far and shallow. Can do w/out 0degree w/0.1km better vert reoslution. 50+dBZ in cells to NE ~100km out. 0432 New scans time out just fine. Basically at 5.7deg/sec you get 14 tilts to play with. The NE system is really nice, mult cells w/ peak Zh approaching 60dBZ. Far mode seems pretty good now. 0500 NE system is really looking nice, 50-60dBZ area expanding. All echoes being topped except some close-in anvil from main storm, no biggie. 0530 Synched OK, not much sea clutter tonight, centre of NE storm ~80km range 0534 Storm has the appearence of a SW-NE oriented line with some strat behind it to the SE. Sort of a mini 40km-long MCS. Don't think kinematics are similar though. 0549 System propagating NW, although anvil is blowing towards the SW. 0600 New cells near NOAA prof. too bad not set up yet. Movie shows sw prop of cells from upper SMO, then collision with cells further in leading to strengthening and WNW propagation. Anvil still blows SW and smaller NOAA cells going SW too. 0621 System overall looks to be weakening 0632 Some incoming convection to the far north 0634 Weak cell within 30km that may not be getting topped but don't want to loose vert res on far stuff. Alot of it may be bright band anyway. 0649 NE storm now basically strat rain and anvil 0700 Running climofar at 6deg/sec in NAME_micro.scn while I fix it. Cut off prev )deg scan when it finished over the ocean. 0715 Now running climofar in NAME_prof while I fix these scans. Profiler sequence now 3 PPI/RHIs due to longer rain map (5.7deg/sec rot). Timed to run approx a minute short to facilitate switching 0724 Nice brightand in stratiform precip 0730 Back on real low PRF climo far, Northern long-range storm looking pretty good with lots of 50dBZ echo. Potential comparison case with Guasave! 0748 N. Storms main centers of activity now, distance near 150km out NNW of SPOL. 0809 Sprinkling at SPOL may do vertically pointing soon 0821 Doing vertcially pointing scan seq. Restart climo sequence at 0830; Zdrs look a bit negative. 0830 Restarted climofar. Will loikely run late. Nice cell near 315deg, 100km: Far N stuff has dissipated in intensity. Now most activity is along 315deg radial at 100km and fuirther out beyond our range. 0845 'Bump to next scan' didn't work. Restarted late again. Will cut off 0deg 360 and restart manually at 0900 0900 Restart, lost half of 0deg 0935 New development to south 0945 Started CLimonear. Not sure it will tops torm as it is within 20km. 50+dBZ in cell to south. 1012 20-30 flashes per minute in cell 1014 climonear not topping cell within 25km 1018 Will tack on some RHIs instead of sea-breeze and highest elev 1025 running RHIs, storms show intense vertical development with a Zdr column 1030 RUnning climonear again. New cells nr 80km, 160deg. Most stuff over water now. 1043 Now topping storm pretty well. CLimonear works! 1048 S cell weakening, se cells waxing. Switch to climofar next as much easier to top SE cerll now. Speeding up climofar to 5.8deg/sec to ensure good synching when we go to unattended after this shift. 1058 Running RHIs as storm is topped, show dissipating storm. 1100 Running climofar, SE storms still going strong 1117 Cekk to south basically gone now, SE storm still OK, mid-50s dBZ 1130 Synch OK, SE storm still looks OK, highest Zh drawn alonmg thin line 1145 SE storm still looks great, 50+dBZ 1158 Unattended ops with climofar scans. SE storm highly electrified. 1812 Dave Ahijevych here. Not much happening except a line 40km offshore. Shallow enogh for climoshallow. When I aarrived it was just doing Don's test scans. 1815 Resynched climoshallow 1819 Running at 720Hz since I got here. It ran at 860Hz til 8am (14Z) until Don and Jonathon took it down for testing. 1826 Took it out of testing at 1812Z. It was not recording prior to this period. Hopefully not many storms were left between 14 and 18Z. 1828 Topping offshore storms easily, going up to 5.5deg elevation. 1831 Very evident line in velocity, reflectivity ~35km offshore. 1833 Last sequence ran long, so it hung at 1830, waiting for next 15min mark. Will restart at 1844 1835 Some cells popping 130-150km to the ENE 1839 Speeding up shallow scan from 5.7deg/sec to 5.8 to bring sequence under 15min. 1845 Restarted climoshallow 1928 90km, 45deg has a cell topped at 5.5deg elevation 1944 5.5deg still topping bubbling convection over high terrain. 2002 Some higher cells 120-180km to north; 50dBZ core. 2003 Synoptic situation: slightl;y higher winds from the east today in the mid-levels brings better chance for MCS movement towards shore. 2020 Cells to north and east at 120km are not topped at 5.5 deg elevation, but SR says it's too far to get polarimetric data on them anyway, so keeping climoshallow. 2030 Switched to climofar. Cells 90km to east must be topped. 55dBZ cores. Tops to 14.5km in northern storm. 89km, 9.2deg ~ 14.22 w/o earth curvature. 14.68 with. 2055 Cell 79km to ESE just below 10.4deg 2059 Zdr brightband due to bugs 2121 Northern and Eastern cells died. Now northeastern cells at 60-90km out. 2135 Cells as close as 50km at 55deg. 14deg el doesn't quite top it. 2154 A discrete jump southwestward is evident with developing cells 25-35km to the NNE of SPOL 2203 64dBZ core at 90km, 55deg 3deg elevation 2220 Tiny vel couplet and associated curl in dBZ field at 67km, 45deg azimuth 4.5 deg elevation. 2222 Not topping storms 20-50km to the north. Quite strong storms 2230 New linear development to NNw along coastal plains. 2236 Request from SR to submit SPOL status to JOSS website 2240 Lots of vel structure due to up/downdraughts in storms to north at 30km 2254 RHIs. Zdr column to approx -10C. 65dBZ peak. 2300 Climonear. SHould have switched sooner 2311 Still scanning higher 26deg elevation got most of storm. Everything was 25dBZ or less. 2342 Still pretty strong cores 2348 Nice gust front 2351 Should pick up movement now with surging cold pool ahead of it 2356 Rit and Steve left
