Aspen training dropsondes 1) 20140912 0927z -good drop -note typical fall rates of 10-12 m/s near surface 2) 20140912 0953z -good drop -note typical fall rates of 10-12 m/s near surface 3) 20130824 2212z -impressive Saharan Air Layer (SAL) sounding (~500-850 mb) -note the strong low level temperature inversion -note the low- to mid-level easterly jet in the SAL layer 4) 20130824 2008z: fastfall -here the parachute didn’t deploy correctly -note the very fast fall rates (dz/dt) at the top of the sounding -note the pendulum swing of the fall rate in the mid-level (parachute issue) -note the very fast fall rate at the surface (~20 m/s) -for fastballs, always flag speed and direction -for fastballs, pressure, T, RH are usually ok, but double check that they look reasonable 5) 20140912 1017z: near surface speed ramp up anomaly -note the ramp up of several m/s at the near surface (GPS signal issue) -flag these winds from the inflection point to the surface (i.e. below 1006.6 mb) -this flagging needs to be done be done from the raw tab 6) 20140912 1431z: did not hit surface -uncheck “hit surface” in the main tab and recompute sounding -all other parameters look ok 7) 20140912 1508z: Not processed/corrupt D file -this dropsonde is corrupt and contains no data -do not send this ob to the NWS Gateway (i.e. do not email this ob) 8) 20110309 235444z (WISPAR): good drop (missed atmospheric river; near NW Pacific low) -strong surface winds: 41 kt -strong jet 250-525 mb: 135 kt at ~300 mb -as expected, the tropopause is lower than typical tropical soundings (~270 mb) 9) 20110309 234559z (WISPAR): good drop (nicked atmospheric river) -low level dry air/dry adiabatic lapse rate below 900 mb -possible atmospheric river: 80-90% RH 600-700 mb -surface temperature: 12.3 (54F); reasonable off the north CA coast (confirmed with SST analysis)
