Twentieth century secular decrease in the atmospheric potential gradient [PDF]

, 2002
Current flowing in the global atmospheric electrical circuit (AEC) substantially decreased during the twentieth century. Fair-weather potential gradient (PG) observations in Scotland and Shetland show a previously unreported annual decline from 1920 to ...

Moist convection and radiative cooling: Dynamical response and scaling

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The mechanism that sets the updraught velocities in deep convective clouds is studied here using cloud‐resolving model simulations in radiative–convective equilibrium. We show that, for simulations with vastly different rates of radiative cooling and surface temperatures, the buoyancy in clouds remains remarkably constant (histogram shown here).

Remote Sensing Observations of Thunderstorm Features in Latvia

Environmental and Climate Technologies, 2017
Thunderstorms are the most hazardous meteorological phenomena in Latvia in the summer season, and the assessment of their characteristics is essential for the development of an effective national climate and weather prediction service.

The Error is the Feature: how to Forecast Lightning using a Model Prediction Error

, 2019
Despite the progress within the last decades, weather forecasting is still a challenging and computationally expensive task. Current satellite-based approaches to predict thunderstorms are usually based on the analysis of the observed brightness ...

The stratospheric gravity wave field produced by a supercell

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Supercells are a class of long‐lasting thunderstorms with rotating updrafts that often cause severe weather, hail, and tornadoes. This study uses numerical simulations to characterize the stratospheric gravity waves that are caused by these storms.

Do metal objects such as mobile phones increase lightning risk?

Geomatics, Natural Hazards & Risk, 2021
This study has been carried out to test two hypotheses; whether a small metal object such as mobile phones in possession of a human body increases the chances of a direct lightning strike and whether a similar object increases the chances of a side flash.

The mesospheric inversion layer and sprites

, 2009
The vertical structure of temperature observed by SABER (Sounding of Atmosphere using Broadband Emission Radiometry) aboard TIMED (Thermosphere, Ionosphere, Mesosphere Energetics and Dynamics) and sprites observations made during the Eurosprite 2003 to ...

The challenge of predicting flash floods from thunderstorm rainfall. [PDF]

, 2002
A major characteristic of the hydrometeorology of semi-arid regions is the occurrence of intense thunderstorms that develop very rapidly and cause severe flooding.

Estimating Rain‐Specific Attenuation at Extremely High Frequencies From Disdrometer Measurements at Various Climate Zones in the US

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT The raindrop size distribution (DSD) plays an essential role in understanding rain attenuation effects at extremely high frequencies (EHFs). Over 1 year of DSD measurements was taken at different Köppen–Geiger climate classifications within the United States. Optical disdrometers from Thies Clima were used to measure both the size and velocity
