Roll Vortices in the Boundary Layer Caused by a Concave Wind Profile: A Theoretical Study
Atmospheric and Oceanic Science Letters, Volume 3 Number 6. Liu Hui-Zhi; Sang Jian-Guo - Science Press, 2010The present study solves a two-layer atmospheric wave equation model with a lower atmosphere concave wind profile and cold-air outbreak over sea, while simultaneously proving that such a wind shear may cause neutral boundary layer roll vortices in the presence of disturbing sources upstream. Without thermal effects, the wind shear-induced waves have band structures at the top of the boundary layer that are similar to cloud street patterns observed over sea. This study proves that dynamic and thermal effects can act independently to initiate the roll vortices in the lower atmosphere. At the sam ...

The Observed Low CO2 Concentration in the Rongbuk Valley on the Northern Slope of Mt. Everest
Atmospheric and Oceanic Science Letters, Volume 3 Number 5. Zhou Li-Bo; Ma Shu-Po; Li Peng; et al. - Science Press, 2010In the summers of 2006 and 2007, the atmospheric CO2 concentration and the wind speed in the Rongbuk Valley on the northern slope of Mt. Everest were measured by an ultrasonic anemometer with an Li-7500 CO2/H2O gas analyzer. The average CO2 concentration was 370.23±0.59 and 367.45±1.91 ppm in June of 2006 and 2007, respectively. The values are much lower than those at sites with similar latitudes and altitudes worldwide. The observed atmospheric CO2 concentration in Rongbuk Valley can be affected by the transportation of prevailing down-valley winds from the up-valley direction to the observat ...

Spatial Distributions of Atmospheric Radiative Fluxes and Heating Rates over China during Summer
Atmospheric and Oceanic Science Letters, Volume 3 Number 5. Yang Da-Sheng; Wang Pu-Cai - Science Press, 2010The latitude-altitude distributions of radiative fluxes and heating rates are investigated by utilizing CloudSat satellite data over China during summer. The Tibetan Plateau causes the downward shortwave fluxes of the lower atmosphere over central China to be smaller than the fluxes over southern and northern China by generating more clouds. The existence of a larger quantity of clouds over central China reflects a greater amount of solar radiation back into space. The vertical gradients of upward shortwave radiative fluxes in the atmosphere below 8 km are greater than those above 8 km. The la ...

Analysis of South Asian Monsoons within the Context of Increasing Regional Black Carbon Aerosols
Atmospheric and Oceanic Science Letters, Volume 3 Number 4. Mahmood Rashed; Yao Jin-Feng - Science Press, 2010South Asian monsoons were analyzed within the context of increasing emissions of black carbon (BC) aerosols using a global atmospheric general circulation model. The BC aerosols were allowed to increase only over the south Asian domain to analyze the impacts of regional black carbon over the climatological patterns of monsoons. The black carbon significantly absorbed the incoming short wave radiation in the atmosphere, a result that is consistent with previous studies. Pre-monsoon (March-April-May) rainfall showed positive anomalies, particularly for some coastal regions of India. The summer ( ...

Interannual Variability of Snow Depth over the Tibetan Plateau and Its Associated Atmospheric Circulation Anomalies
The interannual variability of wintertime snow depth over the Tibetan Plateau (TP) and related atmospheric circulation anomalies were investigated based on observed snow depth measurements and NCEP/NCAR reanalysis data. Empirical orthogonal function (EOF) analysis was applied to identify the spatio-temporal variability of wintertime TP snow depth. Snow depth anomalies were dominated by a monopole pattern over the TP and a dipole structure with opposite anomalies over the southeastern and northwestern TP. The atmospheric circulation conditions responsible for the interannual variability of TP s ...

Kolmogorov Constants of Atmospheric Turbulence over a Homogeneous Surface
Atmospheric and Oceanic Science Letters, Volume 3 Number 4. Cheng Xue-Ling; Wang Bing-Lan; Hu Fei; et al. - Science Press, 2010In this paper, the authors use ultrasonic data over a homogeneous surface to calculate the Kolmogorov constants of velocity, temperature, CO2, and water vapor. The authors find that the constants are all within the range determined by former experiments and that they are universally independent of the stability.

Comparisons of Low-Level Circulation Characteristics between ECHAM5/MPI-OM Results and NCEP/NCAR Re-Analysis Data in East Asia
Atmospheric and Oceanic Science Letters, Volume 3 Number 4. Zhao De-Ming; Fu Cong-Bin - Science Press, 2010Regional climate models (RCMs) can provide far more precise information than general circulation models (GCMs). However, RCMs depend on GCM results for re-analysis products providing boundary conditions, especially for future climate scenarios. Meanwhile, the capacity of RCMs to reproduce precipitation is strongly connected to its performance on circulation and moisture transport simulations in the low troposphere, which is the key problem with RCMs at present. In the Regional Climate Model Inter-comparison Project for East Asia (RMIP III), the results of ECHAM5/MPI-OM (the European Centre-Ham ...

Diapycnal Mixing in Transient Responses of the Atlantic Meridional Overturning Circulation in an Enhanced Freshwater Perturbation Experiment
Atmospheric and Oceanic Science Letters, Volume 3 Number 4. Yu Lei; Gao Yong-Qi; Helge Drange; et al. - Science Press, 2010It has been reported recently that the simulated Atlantic meridional overturning circulation (AMOC) using the coupled Bergen climate model (BCM) showed initial intensity declines followed by gradual recoveries over a 150-year enhanced freshwater input experiment. Stratification-dependent oceanic diapycnal mixing has been hypothesized as a reason for the simulated recovery of the AMOC. This study investigated the role of diapycnal mixing in transient responses of simulated AMOCs. Our results showed that stratification-dependent diapycnal mixing can cause stronger upwelling of deep water in the ...

The Relationship between Total Ozone and Local Climate at Kunming Using Dobson and TOMS Data
Atmospheric and Oceanic Science Letters, Volume 3 Number 4. Wang Jun; Wang Hui-Jun - Science Press, 2010This paper uses Dobson spectrometer total ozone data, Total Ozone Mapping Spectrometer (TOMS) data and radiosonde reports from Kunming, which is located in southwest China, from 1980 to 2008 to analyze the total ozone-climate relationship. The total ozone decadal long-term trend and abrupt change were studied using enhanced Dobson data whose missing data were amended by the TOMS data. Stepwise linear regression was used for the selection of the key factors that influence total ozone, including temperatures, geopotential heights, depressions of the dew point, wind velocities, and total solar ra ...

Aerosol Indirect Effects on Warm Clouds in the Grid-Point Atmospheric Model of IAP LASG (GAMIL)
Atmospheric and Oceanic Science Letters, Volume 3 Number 4. Shi Xiang-Jun; Wang Bin; Liu Xiao-Hong; et al. - Science Press, 2010Aerosol indirect effects on warm clouds are estimated in the Grid-point Atmospheric Model of IAP LASG (GAMIL) with a new two-moment cloud microphysics scheme using two different physically-based aerosol activation parameterizations: Abdul-Razzak and Ghan, and Nenes and Seinfeld. The annual global mean changes in shortwave cloud forcing from preindustrial times to present day (a measure of the aerosol indirect effects) estimated from these two parameterizations are remarkably similar: 0.76 W m-2 with the Abdul-Razzak and Ghan parameterization, and 0.78 W m-2 with the Nenes and Seinfeld paramete ...

Cloud effects on erythemal UV radiation in a complex topography
Walker Daniel - Confédération Suisse, 2010UV radiation is part of the solar spectrum with wavelengths between 100 and 400 nm. In this study, erythemal UV is investigated; a measure directly related to the harmfulness of
solar radiation to our skin. UV radiation has important impacts on di?fferent ecosystems, life and also on public health. Therefore, detailed information about the spatial distribution of UV radiation and its temporal evolution is required. Since observations are spatially and temporally sparse, these issues are often approached by radiative transfer modeling. These models perform well for simulating UV radiatio ...
