Long-Term Statistics of Riming in Nonconvective Clouds Derived from Ground-Based Doppler Cloud Radar Observations
Publisher: American Meteorological Society
Abstract: Riming is an efficient process of converting liquid cloud water into ice and plays an important role in the formation of precipitation in cold clouds. Due to the rapid increase in ice particle mass, riming enhances the ...
Polarimetric Spectral Filter for Adaptive Clutter and Noise Suppression
Publisher: American Meteorological Society
Abstract: In this paper, spectral decompositions of differential reflectivity, differential phase, and copolar correlation coefficient are used to discriminate between weather and nonweather signals in the spectral domain. This ...
Nonparametric Estimation of Raindrop Size Distributions from Dual-Polarization Radar Spectral Observations
Publisher: American Meteorological Society
Abstract: This paper presents a method to retrieve raindrop size distributions (DSD) from slant profile dual-polarization Doppler spectra observations. It is shown that using radar measurements taken at a high elevation angle raindrop ...
Examination of the μ–Λ Relation Suggested for Drop Size Distribution Parameters
Publisher: American Meteorological Society
Abstract: Raindrop size distributions are often assumed to follow a three-parameter gamma distribution. Since rain intensity retrieval from radar observations is an underdetermined problem, there is great interest in finding physical ...
Advection-Based Adjustment of Radar Measurements
Publisher: American Meteorological Society
Abstract: hen making radar-based precipitation products, a radar measurement is commonly taken to represent the geographical location vertically below the contributing volume of the measurement sample. However, when wind is present ...
A Climatology of Disdrometer Measurements of Rainfall in Finland over Five Years with Implications for Global Radar Observations
Publisher: American Meteorological Society
Abstract: o improve the understanding of high-latitude rain microphysics and its implications for the remote sensing of rainfall by ground-based and spaceborne radars, raindrop size measurements have been analyzed that were collected ...
Kalman Filtering–Based Probabilistic Nowcasting of Object-Oriented Tracked Convective Storms
Publisher: American Meteorological Society
Abstract: he weather radar?based object-oriented convective storm tracking is a standard approach for analyzing and nowcasting convective storms. However, the majority of current storm-tracking algorithms provide nowcasts only in a ...
Clutter Suppression for Staggered PRT Waveforms
Publisher: American Meteorological Society
Abstract: This paper presents a clutter suppression methodology for staggered pulse repetition time (PRT) observations. It is shown that spectral moments of precipitation echoes can be accurately estimated even in cases where ...
A Parametric Time Domain Method for Spectral Moment Estimation and Clutter Mitigation for Weather Radars
Publisher: American Meteorological Society
Abstract: A parametric time domain method (PTDM) for clutter mitigation and precipitation spectral moments? estimation for weather radars is introduced. Use of PTDM allows for the simultaneous estimation of clutter and precipitation ...
Radar Backscattering from Snowflakes: Comparison of Fractal, Aggregate, and Soft Spheroid Models
Publisher: American Meteorological Society
Abstract: he sensitivity of radar backscattering cross sections on different snowflake shapes is studied at C, Ku, Ka, and W bands. Snowflakes are simulated using two complex shape models, namely, fractal and aggregate, and a soft ...
