英文摘要 | The bulk microphysical properties and number distribution functions (N(D)) of supercooled liquid water (SLW) and ice inside and between ubiquitous generating cells (GCs) observed over the Southern Ocean (SO) during the Southern Ocean Clouds Radiation Aerosol Transport Experimental Study (SOCRATES) measured by in situ cloud probes onboard the NCAR/NSF G-V aircraft are compared. SLW was detected inside all GCs with an average liquid water content of 0.31 +/- 0.19 g m(-3), 11% larger than values between GCs. TheN(D)of droplets (maximum dimensionD < 50 mu m) inside and between GCs had only slight differences. For ice particles, on the other hand, the mean concentration (median mass diameter) withD > 200 mu m inside GCs was 2.0 +/- 3.3 L-1(323 +/- 263 mu m), 65% (37%) larger than values outside GCs. AsDincreases, the percentage differences became larger (up to similar to 500%). The more and larger ice particles inside GCs suggest the GC updrafts provide a favorable environment for particle growth by deposition and riming and that mixing processes are less efficient at redistributing larger particles. The horizontal scale of observed GCs ranged from 200 to 600 m with a mean of 395 +/- 162 m, smaller than GC widths observed in previous studies. This study expands knowledge of the microphysical properties and processes acting in GCs over a wider range of conditions than previously available. |
