Giant Sea-Salt Aerosols and Warm Rain Formation in Marine Stratocumulus
Publisher: American Meteorological Society
Abstract: The concentrations and sizes of smaller aerosols (radius smaller than 0.5 ?m) in the marine atmosphere vary owing to natural and anthropogenic factors. The concentrations and sizes of giant and ultragiant aerosols vary ...
Optoelectronic Simulation of the PMS 260X Optical Array Probe and Application to Drizzle in a Marine Stratocumulus
Publisher: American Meteorological Society
Abstract: Measurement of drizzle drop sizes and concentrations are often made using optical probes with linear arrays. Their accuracy is affected by both diffraction of light and response times of the electronics connected to the ...
Condensational Growth of Drops Formed on Giant Sea-Salt Aerosol Particles
Publisher: American Meteorological Society
Abstract: he most basic aspect of cloud formation is condensational growth onto cloud condensation nuclei (CCN). As such, condensational growth of cloud drops is often assumed to be a well-understood process described by the drop ...
A Simple Model of Droplet Spectral Evolution during Turbulent Mixing
Publisher: American Meteorological Society
Abstract: The mixing of cloudy, saturated air with cloud-free, subsaturated air is examined with a simple one-dimensional model of the mixing process. The model incorporates (i) a one-dimensional parameterization of turbulent ...
Calibration of a Lyman-α Sensor to Measure In-Cloud Temperature and Clear-Air Dewpoint Temperature
Publisher: American Meteorological Society
Abstract: A number of previous studies have described how airborne temperature-sensor wetting can lead to erroneous temperature measurements under various conditions. During the 1985 Joint Hawaii Warm Rain Project (JHWRP) a large ...
Numerical Modeling of Orographically Forced Postfrontal Rain
Publisher: American Meteorological Society
Abstract: A nonhydrostatic mesoscale model is used to simulate the dynamics and microphysics of postfrontal flow in the mountainous region of southeastern Australia. The aim of the paper is to determine if it is possible to use 2D ...
A Study of the Source of Entrained Air in Montana Cumuli
Publisher: American Meteorological Society
Abstract: Data gathered by the University of Wyoming King Air, the Atmospheric Environmental Services Twin otter and an NCAR Queen Air were used in thermodynamic analyses to determine the sources of environmental air entrained into ...
Ice Nucleation Parameterization and Relative Humidity Distribution in Idealized Squall-Line Simulations
Publisher: American Meteorological Society
Abstract: AbstractOutput from idealized simulations of a squall line are compared with in situ aircraft-based observations from the Deep Convective Clouds and Chemistry campaign. Relative humidity distributions around convection are ...
Characteristics of Cumulus Band Clouds off the Coast of Hawaii
Publisher: American Meteorological Society
Abstract: We have analyzed aircraft observations from seventeen cumulus cells within cloud bands observed off the east coast of Hawaii during the Joint Hawaii Warm Rain Project (JHWRP) of 1985. Low level convergence generated by the ...
