Clouds greenhouse effect instrumental origin tropical storms
2020/11/6
The tropical storm season in the Atlantic Ocean is already well into the Greek alphabet for naming.Better tropical storm track forecasting has allowed timely preparations and evacuations. However, pre...
Considering the Mediterranean as a region of high evaporation and low precipitation, evaluations of sinks and sources of moisture and precipitation in the Mediterranean basin have been carried out wit...
The summertime “heat” low over Pakistan/northwestern India: evolution and origin
Heat low Desert heating Orographic forcing South Asian monsoon MONSOON DYNAMICS DESERT CLIMATE TROUGH SEA
2014/5/20
A deep low in sea-level pressure is present from May to September over Pakistan and northwestern India (hereafter, the Pak-India low). It is often referred as the "heat" low to convey the significance...
Chirality and the origin of atmospheric humic-like substances
Chirality atmospheric humic-like substances origin
2010/2/21
Aerosol water extracts and atmospheric humic-like substances (HULIS) obtained from PM2.5-fraction aerosol samples collected in a rural/continental background environment and in an urban environment in...
High resolution cyclostratigraphy of the early Eocene–new insights into the origin of the Cenozoic cooling trend
X-ray fluorescence Geomagnetic Polarity Time Scale Early Eocene Climatic Optimum
2009/12/3
Here we present a high-resolution cyclostratigraphy based on X-ray fluorescence (XRF) core scanning data from a new record retrieved from the tropical western Atlantic (Demerara Rise, ODP Leg 207, Sit...
Origin of aerosol particles in the mid-latitude and subtropical upper troposphere and lowermost stratosphere from cluster analysis of CARIBIC data
aerosol particles troposphere lowermost stratosphere CARIBIC data
2009/11/19
The origin of aerosol particles in the upper troposphere and lowermost stratosphere over the Eurasian continent was investigated by applying cluster analysis methods to in situ measured data. Number c...
Toward an understanding of the nonlinear nature of atmospheric photochemistry:Origin of the complicated dynamic behaviour of the mesospheric photochemical system
nonlinear nature atmospheric photochemistry dynamic behaviour mesospheric photochemical system
2009/11/12
The methods of nonlinear dynamics are used to reveal the origin of complicated dynamic behaviour (CDB) of a dynamic model of the mesospheric photochemical system (PCS) perturbed by diurnal variations ...
On the origin of tropospheric O3 over the Indian Ocean during the winter monsoon: African biomass burning vs. stratosphere-troposphere exchange
tropospheric O3 Indian Ocean winter monsoon African biomass stratosphere-troposphere exchange
2009/3/12
This study investigates the origin of a commonly observed feature in the O3 profiles: mid tropospheric O3 maxima (300--500 hPa) over the tropical Indian Ocean. A comparison and analysis of model simul...
Origin of anthropogenic hydrocarbons and halocarbons measured in the summertime european outflow
anthropogenic hydrocarbons summertime european outflow
2009/3/11
During the Mediterranean Intensive Oxidant Study MINOS in August 2001, 87 air samples were collected at the ground-based station Finokalia (35°19'N, 25°40'E) on the north coast of Crete and subsequent...
The origin of sea salt in snow on Arctic sea ice and in coastal regions
sea salt snow Arctic sea ice coastal regions
2009/3/10
Snow, through its trace constituents, can have a major impact on lower tropospheric chemistry, as evidenced by ozone depletion events (ODEs) in oceanic polar areas. These ODEs are caused by the chemis...
Physical aerosol properties and their relation to air mass origin at Monte Cimone (Italy) during the first MINATROC campaign
Physical aerosol properties air mass origin Monte Cimone MINATROC campaign
2009/2/16
Aerosol physical properties were measured at the Monte Cimone Observatory (Italy) from 1 June till 6 July 2000. The measurement site is located in the transition zone between the continental boundary ...
The origin of ozone
origin of ozone
2009/1/7
Highest atmospheric ozone production rates can be found at around 30 km in the tropical stratosphere, leading to ozone mixing ratios of about 10 ppmv. Those stratospheric air masses are then transport...
Size distributions of non-volatile particle residuals（Dp<800 nm）at a rural site in Germany and relation to air mass origin
non-volatile particle rural site Germany air mass origin
2008/12/25
Atmospheric aerosol particle size distributions at a continental background site in Eastern Germany were examined for a one-year period. Particles were classified using a twin differential mobility pa...
Nitrogen and oxygen isotopic constraints on the origin of atmospheric nitrate in coastal Antarctica
Nitrogen oxygen isotopic constraint atmospheric nitrate coastal Antarctica
2008/12/8
Throughout the year 2001, aerosol samples were collected continuously for 10 to 15 days at the French Antarctic Station Dumont d'Urville (DDU) (66°40' S, l40°0' E, 40 m above mean sea level). The nitr...
This paper presents a systematic way to examine the origin of variety in falling snow. First, we define shape diversity as the logarithm of the number of possible distinguishable crystal forms for a g...
