Research shows ice sheets as large as Greenland’s melted fast in a warming climate(图)
ice sheets as large as Greenland’s melted fast warming climate
2017/11/24
New research published in Science shows that climate warming reduced the mass of the Cordilleran Ice Sheet by half in as little as 500 years, indicating the Greenland Ice Sheet could have a similar fa...
Future wildfires may burn large parts of landscapes
Future wildfires burn large parts landscapes
2015/10/13
Wildfire history over the past 2,000 years in Colorado's mountains indicates that large fires will continue to increase in a warming climate, according to results of a new study."Even modest regional ...
Regime dependent instability as a transition mechanism in large-scale atmospheric flow
regimes instability baroclinic
2015/9/30
Two apparently distinct approaches to studying the observed low frequency variability in the atmosphere have evolved over the past few years. One approach invokes multiple, recurrent flow regimes to e...
Automated tracking of shallow cumulus clouds in large domain, long duration large eddy simulations
shallow cumulus clouds large domain
2014/12/12
This paper presents a method for feature tracking of fields of shallow cumulus convection in large eddy simulations (LES) by connecting the projected cloud cover in
space and time, and by accou...
Mediterranean hurricanes: large-scale environment and convective and precipitating areas from satellite microwave observations
Mediterranean hurricanes large-scale environment convective precipitating areas satellite microwave observations
2011/1/19
Subsynoptic scale vortices that have been likened to tropical cyclones or polar lows (medicanes) are occasionally observed over the Mediterranean Sea. Generated over the sea, they are usually associat...
Satellite observations of long range transport of a large BrO plume in the Arctic
Satellite observations a large BrO plume the Arctic
2010/8/16
In this study, BrO measurements from the satellite instrument GOME-2 are used together with model calculations with the dispersion model FLEXPART to study an arctic BrO event in March 2007, which coul...
Cyclones causing wind storms in the Mediterranean: characteristics, trends and links to large-scale patterns
Cyclones causing wind storms characteristics trends links to large-scale patterns
2010/10/21
A climatology of cyclones with a focus on their relation to wind storm tracks in the Mediterranean region (MR) is presented. Trends in the frequency of cyclones and wind storms, as well as variations ...
During two field campaigns (OP3 and ACES), which ran in Borneo in 2008, we measured large emissions of estragole (methyl chavicol; IUPAC systematic name 1-allyl-4-methoxybenzene; CAS number 140-67-0) ...
Characterization of a large biogenic secondary organic aerosol event from eastern Canadian forests
a large biogenic secondary organic aerosol event eastern Canadian forests
2010/8/12
Measurements of aerosol composition, volatile organic compounds, and CO are used to determine biogenic secondary organic aerosol (SOA) concentrations at a rural site 70 km north of Toronto. These biog...
Parameterization of subgrid plume dilution for use in large-scale atmospheric simulations
Parameterization subgrid plume dilution large-scale atmospheric simulations
2010/3/16
A new model of plume dynamics has been developed for use as a subgrid model of plume dilution in a large-scale atmospheric simulation. The model uses mean wind, shear, and diffusion parameters derived...
Chaotic background of large-scale climate oscillations
Chaotic background large-scale climate oscillations
2010/4/6
It is shown that the periodic alteration of night and day provides a chaotic dissipation mechanism for the North Atlantic (NAO) and Southern (SOI) climate oscillations. The wavelet regression detrende...
Electrical generation by wind turbines is increasing rapidly, and has been projected to satisfy 15% of world electric demand by 2030. The extensive installation of wind farms would alter surface rough...
Large-scale upper tropospheric pollution observed by MIPAS HCN and C2H6 global distributions
Large-scale upper tropospheric pollution MIPAS HCN C2H6
2009/12/31
We present global upper tropospheric HCN and C2H6 amounts derived from MIPAS/ENVISAT limb emission spectra. HCN and C2H6 are retrieved in the spectral regions 715.5–782.7 cm−1 and 811.5–835.7 cm...
Initial fate of fine ash and sulfur from large volcanic eruptions
Initial fate fine ash large volcanic eruptions
2009/12/3
Large volcanic eruptions emit huge amounts of sulfur and fine ash into the stratosphere. These products cause an impact on radiative processes, temperature and wind patterns. In simulations with a Gen...
