Mobile Integrated Profiler System (MIPS) Observations of Low-Level Convergent Boundaries during IHOP

摘要: Abstract Characteristics of convergent boundary zones (CBZs) sampled by the Mobile Integrated Profiling System (MIPS) during 2002 International H2O Project (IHOP_2002) are presented. The MIPS sensors (915-MHz wind profiler, 12-channel microwave profiling radiometer, ceilometer, and surface instrumentation) provide very fine temporal kinematic thermodynamic profiles atmospheric layer CBZ properties, including enhanced 915-MHz backscatter within updraft (equivalent to radar line), a general increase in integrated water vapor updrafts CBZ, an convective (CBL) depth, changes ceilometer that typically coincident with arrival cooler, moister air (the case for density current CBZ). Three contrasting CBZs analyzed. Convective initiation was associated slow-moving dryline as it passed over on 19 June. Updrafts up 6 m s−1 were measured, CBL attained its greatest dept...
