Abstract: During the Joint Airport Weather Studies (JAWS) project in 1982, the University of Wyoming's King Air research aircraft made observations of raindrop size distributions, vertical and horizontal air motions, and the temperature ...

Abstract: Determination of the horizontal pressure gradient force over distance scales less than 100 km is possible using airborne altimetry and detailed maps of the underlying terrain. To detect the very small isobaric slopes, ...

Abstract: In July 1987 during the CINDE project, three similar mesoscale planetary boundary layer convergence zones were observed to form in northeastern Colorado near Denver under synoptic-scale southwesterly flow. A number of ...

Abstract: A new airborne thermometer has been designed using results from numerical simulators of airflow and particle (drop) trajectories. Initial flight tests with the NCAR King Air show that the new thermometer, which uses a ...

Abstract: The effect of seeding convective clouds with dry ice was studied using simultaneous aircraft and radar observations. Clouds that were initially ice-free with supercooled liquid water contents of 0.5 g m?3 when the tops ...

Abstract: Recently published ground-based measurements of liquid water content (LWC) measured in fogs by two microphysical instruments, the FSSP-100 and PVM-100, are evaluated. These publications had suggested that the PVM-100 ...

Abstract: Aircraft distance-measuring-equipment (DME) data are used to update position, velocity, and wind measurements from inertial navigation systems (INS) measurements. Data from conventional single-channel DME sets, suitably ...

Abstract: Relative dispersion of ice crystals was measured in 30 seeded cumulus clouds. A quasi-instantaneous, vertical area source of ice was generated by releasing dry-ice pellets from an airplane. The ice concentration distribution ...

Abstract: A case study of the kinematical and dynamical evolution of the summertime Great Plains low level jet (LLJ) is presented. Airborne radar altimetry was used to discern the x and y components of the geostrophic wind at three ...
