Most U.S. metropolitan regions have experienced urban ‘‘sprawl,’’ or the outward spreading of urban development from city centers. For cities lying in areas prone to severe weather, the sprawl phenomenon exposes greater numbers of developed areas and inhabitants to a variety of thunderstorm hazards. This study’s principal goal is to determine how urbanization growth patterns affect a region’s v...

[1] Water vapor in the lower stratosphere may play significant roles in the atmospheric radiative budget and atmospheric chemistry; hence it is important to understand its transport process. The possibility of water vapor transport from the troposphere to the stratosphere by deep convection is investigated using three-dimensional, nonhydrostatic, quasi-compressible simulations of a Midwest seve...

ABSTRACT: It has been realized in recent years that the ionospheric temperature and ion density may be influenced by lightning. The ionospheric ion densities (O, O2 , H and He) and electron and ion temperatures were measured by the RPA payload aboard the Indian SROSS-C2 satellite. The data at low latitudes falling in the Indian subcontinent in the height range 425 – 625 km for the period 1995–1...

Progresses in the research on physical processes of lightning discharge and electric structure of thunderstorm in the last decade in China have been reviewed. By using the self-developed lightning detecting and locating techniques with high temporal and spatial resolution, the characteristics and parameters of lightning discharge in some representative areas in China have been obtained. Observa...

Ground-based measurements of ozone and NO2 differential slant columns by the SAOZ (Système d’Analyse par Observations Zénithales) and UT-GBS (University of Toronto Ground-Based Spectrometer) instruments during the MANTRA 2004 field campaign are presented herein. During the afternoon of 28 August, a thunderstorm passed over the instruments, which were installed at Vanscoy, Saskatchewan (52 N, 10...

Lightning is one of the major threats to multimegawatt wind turbines and a concern for modern aircraft due to the use of lightweight composite materials. Both wind turbines and aircraft can initiate lightning, and very favorable conditions for lightning initiation occur in winter thunderstorms. Moreover, winter thunderstorms are characterized by a relatively high production of very energetic li...

thunderstorms are regarded not only as a significant weather event but also as a key element in water and electricity cycles of the atmosphere. generally, researchers consider the intense weather instability as a result of convection in lower levels of the atmosphere with high levels enough of humidity. usually statistic instability, the humidity of lower levels of the atmosphere and lifting me...

The impact of thunderstorms on the wildfire situation in Australia 2017–2020 was investigated using data from ISS LIS and MODIS space-based observations. To determine lightning-caused wildfires, a Geographic Information System (GIS) method carried out, which consisted combined investigation spatial temporal distributions strikes ignition hotspots. seasonal variability activity analyzed. It esta...
