MICROCLIMATE ANALYSIS OF DIFFERENT URBAN FORMS IN COLD CLIMATES AND THE EFFECT OF THERMAL COMFORT
Urban Microclimate Urban Geometry Outdoor Thermal Comfort Cold Climate Erzurum
2018/11/9
In this study, it is aimed to understand the relation between micro-climate and urban planning in the case of a cold-climate city, Erzurum. The effects of different urban patterns on micro-climate are...
Earth’s atmosphere more chemically reactive in cold climates
Earth’s atmosphere chemically reactive cold climates
2017/7/20
Unseen in the air around us are tiny molecules that drive the chemical cocktail of our atmosphere. As plants, animals, volcanoes, wildfires and human activities spew particles into the atmosphere, som...
Study:Cold Climates and Ocean Carbon Sequestration
Cold Climates Ocean Carbon Sequestration
2017/3/30
We know a lot about how carbon dioxide (CO2) levels can drive climate change, but how about the way that climate change can cause fluctuations in CO2 levels? New research from an international te...
Like hurricanes,unseasonable cold spells wipe out subtropical species
hurricanes unseasonable cold spells wipe out subtropical species
2016/11/4
Two cold spells, two years apart, in two subtropical regions of the world have given scientists clues about what happens when an extreme climate event strikes.
By tracking conditions before, during a...
Laboratory investigations of the impact of mineral dust aerosol on cold cloud formation
mineral dust aerosol cold cloud formation Laboratory
2010/12/28
Dust particles represent a dominant source of particulate matter (by mass) to the atmosphere, and their emission from some source regions has been shown to be transported on regional and hemispherical...

frontal depression affected the area Cyprus
2010/10/21
The baroclinic depression that affected the area of Cyprus during the cold period, between 28 and 29 January 2008 was thoroughly studied and is presented in the present paper. A small perturbation on ...
Atmospheric transport of persistent semi-volatile organic chemicals to the Arctic and cold condensation in the mid-troposphere – Part 2: 3-D modeling of episodic atmospheric transport
Atmospheric transport persistent semi-volatile organic chemicals the Arctic and cold condensation the mid-troposphere episodic atmospheric transport
2010/8/16
Two 3-dimensional global atmospheric transport models for persistent organic pollutants (POPs) have been employed to investigate the association between the large-scale atmospheric motions and polewar...

2010/8/16
In the first part of this study for revisiting the cold condensation effect on global distribution of semi-volatile organic chemicals (SVOCs), the atmospheric transport of SVOCs to the Arctic in the m...
Investigating the impact of Lake Agassiz drainage routes on the 8.2 ka cold event with a climate model
Lake Agassiz drainage routes 8.2 ka cold event climate model
2009/12/3
The 8.2 ka event is the most prominent abrupt climate change in the Holocene and is often believed to result from catastrophic drainage of proglacial lakes Agassiz and Ojibway (LAO) that routed throug...
Cold oceans enhance terrestrial new-particle formation in near-coastal forests
Cold oceans terrestrial new-particle formation near-coastal forests
2009/11/19
The world's forests produce atmospheric aerosol by emitting volatile organic compounds (VOC) which, after being oxidized in the atmosphere, readily condense on the omnipresent nanometer-sized nuclei a...
Factors controlling Arctic denitrification in cold winters of the 1990s
Factors controlling Arctic denitrification cold winters the 1990s
2009/3/10
Denitrification of the Arctic winter stratosphere has been calculated using a 3-D microphysical model for the winters 1994/95, 1995/96, 1996/97 and 1999/2000. Denitrification is assumed to occur throu...
Ice supersaturations exceeding 100% at the cold tropical tropopause: implications for cirrus formation and dehydration
Ice supersaturations cold tropical tropopause cirrus formation dehydration
2009/2/7
Recent in situ measurements at tropical tropopause temperatures as low as 187 K indicate supersaturations with respect to ice exceeding 100% with little or no ice present. In contrast, models used to ...
How cold was Europe at the Last Glacial Maximum? A synthesis of the progress achieved since the first PMIP model-data comparison
