The Large-Scale Response of the Tropical Atmosphere to Cloud-Modulated Infrared Heating
Publisher: American Meteorological Society
Abstract: Infrared beating rates determined from the Line Islands Experiment radiometersonde measurements vary from ?4 to ?0.5°C day?1 at 250 nib. Correspondingly, the beating rates at 500 mb vary from +0.5 to ?3°C day?1. These ...
Procedures for Improving Pyrgeometer Performance
Publisher: American Meteorological Society
Abstract: The actual performance of an Eppley pyrgeometer is compared to the desired theoretical performance. Several systematic errors are identified and evaluated in detail. The three most significant errors identified are due to ...
Why Mie?
Publisher: American Meteorological Society
Abstract: This article demonstrates an innovative method for the observation of vertical air motion and raindrop size distribution in precipitation using a 94-GHz Doppler radar. The method is particularly appealing since it is based ...
Radar Observations of Updrafts, Downdrafts, and Turbulence in Fair-Weather Cumuli
Publisher: American Meteorological Society
Abstract: Observations from a 94-GHz radar are used to define the vertical structure of marine fair-weather cumuli. Doppler spectra obtained from the radar provide mean vertical velocities as well as detailed spectral shapes that ...
Millimeter-Wavelength Radars: New Frontier in Atmospheric Cloud and Precipitation Research
Publisher: American Meteorological Society
Abstract: During the past 20 yr there has been substantial progress on the development and application of millimeter-wavelength (3.2 and 8.6 mm, corresponding to frequencies of 94 and 35 GHz) radars in atmospheric cloud research, ...
An Evaluation of a 94-GHz Radar for Remote Sensing of Cloud Properties
Publisher: American Meteorological Society
Abstract: The performance of a 94-GHz radar is evaluated for a variety of cloud conditions. Descriptions of the radar hardware, signal processing, and calibration provide an overview of the radar's capabilities. An important component ...
The Appearance and Disappearance of Ship Tracks on Large Spatial Scales
Publisher: American Meteorological Society
Abstract: The 1-km advanced very high resolution radiometer observations from the morning, NOAA-12, and afternoon, NOAA-11, satellite passes over the coast of California during June 1994 are used to determine the altitudes, visible ...
Rain in Shallow Cumulus Over the Ocean: The RICO Campaign
Publisher: American Meteorological Society
Abstract: Shallow, maritime cumuli are ubiquitous over much of the tropical oceans, and characterizing their properties is important to understanding weather and climate. The Rain in Cumulus over the Ocean (RICO) field campaign, ...
