Functional Fits to Some Observed Drop Size Distributions and Parameterization of Rain
Publisher: American Meteorological Society
Abstract: A data sample of optical spectrometer measurements that were obtained in two tropical cyclones is analyzed. The resultant drop size distributions are normalized and their shape is found to exhibit some curvature-departure ...
Microphysical Measurements from an Aircraft Ascending with a Growing Isolated Maritime Cumulus Tower
Publisher: American Meteorological Society
Abstract: The development of precipitation in the top of an isolated maritime cumulus tower is traced by four rapid penetrations with an instrumented aircraft between 400 and 1000 m below the visible top of the growing tower. The ...
Observational Grid Spacing Effect on the Accuracy of a Physical Forecast Model
Publisher: American Meteorological Society
Abstract: An error analysis technique is applied to determining the relation between the error in calculated meteoro-logical parameters and the observational grid spacing. For a given instrument type the practical lower limit of ...
Drop-Size Distributions Associated with Intense Rainfall
Publisher: American Meteorological Society
Abstract: The probability of occurrence of extreme rainfall rates is reviewed. The drop-size distributions associated with a range of high rainfall rates are examined using data from tropical storms and hurricanes. Mean drop-size ...
Structure of the Melting Layer in Mesoscale Convective System Stratiform Precipitation
Publisher: American Meteorological Society
Abstract: This study examines the aircraft observations and theoretical evolution of particles above, through, and below the melting layer in the stratiform region associated with a mesoscale convective system (MCS). The aircraft ...
A Z-R Relationship for Hurricanes
Publisher: American Meteorological Society
Abstract: Drop-size measurements taken during hurricane research flight missions at altitudes at or below 3 km were used to derive a relationship between reflectivity factor and rainfall rate. The instrument used in this study is ...
Probability-matched Reflectivity-Rainfall Relations for a Hurricane from Aircraft Observations
Publisher: American Meteorological Society
Abstract: The probability-matching method (PMM) was used to determine the relation between the distribution of equivalent reflectivity Ze measured by an airborne C-band radar and that for concurrently measured rain rate R by a ...
