由于气温升高和降水变化，干旱和半干旱生态系统的干旱加剧，给区域环境、水资源和农业都带来了巨大影响。近些年来，位于干旱和半干旱区的蒙古高原（MP）正在经历着严重的干旱，易发生荒漠化和土地退化等问题。
Planetary wave activity in the polar lower stratosphere
Planetary wave activity polar lower stratosphere
2010/2/1
Temperature data from the COSMIC GPS-RO satellite constellation are used to study the distribution and variability of planetary wave activity in the low to mid- stratosphere (15–40 km) of the Arctic a...

ozone planetary boundary layer dynamics complex topography Grenoble combining measurements
2009/3/10
This paper concerns an evaluation of ozone (O3) and planetary boundary layer (PBL) dynamics over the complex topography of the Grenoble region through a combination of measurements and mesoscale model...
Aerosol Lidar observations and model calculations of the Planetary Boundary Layer evolution over Greece, during the March 2006 Total Solar Eclipse
Aerosol Lidar Planetary Boundary Layer Greece Total Solar Eclipse
2008/12/29
An investigation of the Planetary Boundary Layer (PBL) height evolution over Greece, during the solar eclipse of 29 March 2006, is presented. Ground based observations were carried out using lidar det...
Modelling the direct effect of aerosols in the solar near-infrared on a planetary scale
aerosols solar near-infrared planetary scale
2008/12/12
We used a spectral radiative transfer model to compute the direct radiative effect (DRE) of natural plus anthropogenic aerosols in the solar near-infrared (IR), between 0.85–10 μm, namely, their effec...
Stationary planetary wave propagation in Northern Hemisphere winter – climatological analysis of the refractive index
Stationary planetary wave Northern Hemisphere winter climatological analysis refractive index
2008/11/27
The probability density on a height-meridional plane of negative refractive index squared f(nk2<0) is introduced as a new analysis tool to investigate the climatology of the propagation conditions of ...
Turbulence dissipation rate derivation for meandering occurrences in a stable planetary boundary layer
turbulence dissipation rate derivation meandering occurrences boundary layer
2008/11/3
A new formulation for the turbulence dissipation rate ε occurring in meandering conditions has been presented. The derivation consists of a MacLaurin series expansion of a lateral dispersion parameter...
