Entropy-Based Thunderstorm Imaging System With Real-Time Prediction and Early Warning

IEEE Transactions on Instrumentation and Measurement
A combination of the sample entropy and the artificial intelligence (AI) would hopefully bring progress to the smart thunderstorm detection. In this article, we establish an entropy-based thunderstorm point charge imaging system with data clustering, in ...

The High Speed Updraft—The Key to the Severe Thunderstorm

Journal of the Atmospheric Sciences, 1968
Abstract A model of the motion within a severe storm with some rainfall kinematics is developed from simple hydrodynamic concepts of flow. Based on measured data and descriptive analyses of storms with sufficient data to permit the assumption of a steady state, this paper supports the statement that the large, strong and erect updraft is the single ...

The Velocities of Charged Hydrometeors and the Production of High Fields in Thunderstorms

1976
Calculations of the terminal velocities of charged hydrometeors in the presence of electric fields have been confirmed experimentally. They have formed the basis of computations of the charging current J flowing through a thundercloud as a result of the operation of a precipitative mechanism of cloud electrification.

Lidar Observations of High Plains Thunderstorm Precipitation

Journal of the Atmospheric Sciences, 1977
Abstract The results of a field program using a polarization diversity lidar system to study high plains thunderstorm precipitation are given. The presence of “reflectivity” bright bands of the general form predicted by a numerical simulation indicates that ice prune precipitation processes were predominantly acting in the storm studied.

Severe thunderstorms in the Colombia and Venezuela high lightning active areas

2017 International Symposium on Lightning Protection (XIV SIPDA), 2017
This paper presents a general description of severe thunderstorm episodes detected during the last two years (2015–2016) in the most active lightning regions in Colombia and Venezuela. Hourly and seasonal occurrence characteristics, strokes rates, duration and orographic patterns are described.

Infrasound characteristics of nontornadic and tornadic thunderstorms using high-resolution simulations

The Journal of the Acoustical Society of America, 2020
There has been increased interest in improving severe weather detection by supplementing NOAA's WSR-88D radar network with an infrasound observation network, which may be able to detect distinct sub-audible signatures from tornadic thunderstorms. While there is evidence that tornadic thunderstorms exhibit observable infrasound signals, what is not well-

On the influence of intense thunderstorm activity on high-precision gravimetric observations

Seismic Instruments, 2015
The influence of thunderstorm activity on gravimetric observations has not been considered previously. Based on long-term high-precision gravimetric observations, we have found that thunderstorm activity induces a systematic error in the measured value of gravity acceleration.

Understanding the Radio Spectrum of Thunderstorm Narrow Bipolar Events

Journal of Geophysical Research: Atmospheres, 2019
This paper reports a study to understand the radio spectrum of thunderstorm narrow bipolar events (NBEs) or compact intracloud discharges, which are powerful sources of high‐frequency (HF) and very high frequency (VHF) electromagnetic radiation.

Observations of high-energy radiation during thunderstorms at Tien-Shan

Physical Review D, 2016
Energetic radiation during thunderstorms is studied. The possibility to identify the high-energy lightning emission in the 10 s monitoring mode is demonstrated. Simultaneous measurements of gamma-ray emission, high-energy electrons, and neutron radiation in the triggering mode are fulfilled.

Predicting Thunderstorm-Induced Power Outages to Support Utility Restoration

IEEE Transactions on Power Systems, 2019
Strong thunderstorms have substantial impacts on power systems, posing risks and inconveniences due to power outages. Developing models predicting the outages before a storm is a high priority to support restoration planning.
