Use of Combined Shear and Spectrum Width in Tornado Detection
نویسنده
چکیده
WSR-88D operators have been trained to look for tornado signatures using base reflectivity and storm relative motion. Despite improvements stemming from the implementation of the WSR-88D network, these conventional signatures are not always evident in tornadic situations. At other times, these signatures may exist without tornadic development, even when environmental parameters appear favorable. Research into pre-storm environment and its relation to tornadoes will undoubtedly continue to advance meteorological understanding of the subject. However, radar detection of tornadoes remains essential to the ultimate goal of protecting life and property. Therefore, the radar team at WFO Hastings (GID) decided to evaluate a method of enhancing tornado detection from a radar perspective using spectrum width and combined shear.

A Doppler Radar Emulator with an Application to the Detectability of Tornadic Signatures
A Doppler radar emulator was developed to simulate the expected mean returns from scanning radar, including pulse-to-pulse variability associated with changes in viewing angle and atmospheric structure. Based on the user’s configuration, the emulator samples the numerical simulation output to produce simulated returned power, equivalent radar reflectivity, Doppler velocity, and Doppler spectrum...
متن کاملUsing Wavelet Analysis to Detect Tornadoes from Doppler Radar Radial-Velocity Observations
A wavelet-based algorithm is developed to detect tornadoes from Doppler weather radar radial-velocity observations. Within this algorithm, a relative region-to-region velocity difference (RRVD) is defined based on the scaleand location-dependent wavelet coefficients and this difference represents the relative magnitude of the radial velocity shear between two adjacent regions of different scale...
متن کاملAdjustments in Tornado Counts, F-Scale Intensity, and Path Width for Assessing Significant Tornado Destruction
The U.S. tornado record is subject to inhomogeneities that are due to inconsistent practices in counting tornadoes, assessing their damage, and measuring pathlength and path width. Efforts to improve the modern tornado record (1950–2012) have focused on the following: 1) the rationale for removing the years 1950–52, 2) identification of inconsistencies in F0, F1, and F2 counts based on implemen...
متن کاملISAR Image Improvement Using STFT Kernel Width Optimization Based On Minimum Entropy Criterion
Nowadays, Radar systems have many applications and radar imaging is one of the most important of these applications. Inverse Synthetic Aperture Radar (ISAR) is used to form an image from moving targets. Conventional methods use Fourier transform to retrieve Doppler information. However, because of maneuvering of the target, the Doppler spectrum becomes time-varying and the image is blurred. Joi...
متن کاملInvestigation of the Rigidity of Floor Diaphragms on the Behavior of Concrete Tall Buildings with Staggered Shear Walls under Lateral Loading
In most cases, structural engineers assume a concrete floor to be a rigid diaphragm. Although this simplification is in most cases acceptable, it should be noted that such an assumption may be distrusted due to certain problems. Concrete structures with staggered shear walls are among those whose analysis should be conducted with special concern for the behavior of their floor diaphragms. Howev...
