Introduction: The primary objective of this project is to understand the consequences of glow electrical discharges on the chemistry and biology of Mars. The possibility was raised some time ago that the absence of organic material and carbonaceous matter in the Martian soil samples studied by the Viking Landers might be due in part to an intrinsic atmospheric mechanism such as glow discharge. ...
dust is a common atmospheric phenomenon in iran especially in central arid regions. this severely affects environment as well as resident’s health. among the results of this phenomenon are respiratory diseases, bash radiation, accelerated soil erosion, desertification and degradation of ecosystems. some dusts are originated from local desert conditions but adjacency to neighboring countries de...
Detecting the spatial distribution of dust storms in the deposition regions is an essential step for managing this natural and human-induced crisis. This study aimed to investigate the performance of the Normalized Differences Dust Index (NDDI) applied to MODIS data (4/7/2009) for detection of dust storms in the Khuzestan Province. The extracted NDDI map was classified by value pixel in six cla...
In the Asia/Pacific region there is evidence of prominent increases in the intensity and/or frequency of many extreme events such as heat waves, tropical cyclones, prolonged dry spells, intense rainfall, tornadoes, snow avalanches, thunderstorms, and severe dust storms in the region. Furthermore, the region is highly subject to natural hazards, such as the 2004 Indian Ocean Tsunami, the 2005 Pa...
[1] We have compiled a catalog of frontal dust storms in the northern hemisphere using Mars Orbiter Camera daily global maps spanning 2.3 Martian years of Mars Global Surveyor (MGS) observations (from 1999 to 2003). The most vigorous frontal storms that flush dust to the low latitudes occur in early-mid fall and mid-late winter, away from the northern winter solstice. While many streaks are obs...
OCTOBER 2004 AMERICAN METEOROLOGICAL SOCIETY | A erosols are airborne suspensions of tiny particles, each typically about one-thousandth the diameter of the period at the end of this sentence. Cumulatively, they have profound effects at a variety of scales, exerting myriad influences on the earth’s environment and climate and on human health. Many aerosols originate from natural sources—volcano...

The manufacture of agriculture production products is the most sensitive to meteorological conditions. main risks caused by adverse climate factors that Lithuania’s farmers confront are winterkill, hail, storms, and droughts. aim study analyze expectations crop insurance system participants reveal reasons for encouraging/discouraging farms in insuring their crops Lithuania. All additional means...
Dust storms in northern China strongly affect the living and health of people there and the dusts could travel a full circle of the globe in a short time. Historically, more frequent dust storms occurred during cool periods, particularly the Little Ice Age (LIA), generally attributed to the strengthened Siberian High. However, limited by chronological uncertainties in proxy records, this mechan...
Introduction: Dust devils are an effective aeolian erosion mechanism of small-scale, substantially particle loaded convective vortices driven by insolation, common on both Earth and Mars. These vortices are highly turbulent flows with dust entrainment that is dictated by the surficial material over which they pass, the ambient wind that push them, and the pockets of hot air that power their " e...
