The indexes of dominance vary from 0.3635 to 0.8644, and that of landform, land use and land cover vary from 0.4944 to 0.8449, from 0.3635 to 0.6985, and from 0.5892 to 0.8644 respectively.
Taking the identity— commonness of aeolian sandy landform,as cut-in point,the authors probe into the landform structure and its relation with airflow velocity.
Based on comparison between results from old and new orographic experiments, it is revealed that the originally systemic deviation of modeling on the Western Pacific Subtropical High is related to the negative orography at 30 o N, 120 o E and along the latitude to its east.
The characteristic of orographic cloud precipitation are studied, base on the numerical simulation results of two cases of Qilian mountain orographic cloud in Part I. The orography influence on cloud development is investigated by the intercomparisons of simulation results on complicated terrain and flat surface.
This study analyzed digital elevation data sources and their structure, the arithmetic of terrain attribute extraction from DEM and its applications, and DEM's error and uncertainty algorithm.
Forest watersheds and farmland watersheds with similar terrain features were selected through cluster analysis to study their runoff and sediment transport characteristics.
As for the four transect lines, the east and the northeast scored higher in each diversity index than the others due to less human disturbance, gentler topography uplift and more intercepted materials and energies.
The distribution of microbiotic crusts were studied, while human disturbance, aspect, topography, vegetation structure and other factors affecting it were obtained from the analysis of survey data from 78 sample plots.
Topography and elementary components of the brake block's wear surface are analyzed by employing SEM and EDAX patterns, revealing its tribological behaviour and wear mechanism.
Increasing the grinding depth or the wheel velocity makes grinding temperature and residual tensile stress of the surface rise, which deteriorates the surface topography.
During scanning, AF/PSTM could get two optical images of refractive index image and transmissivity image, and two AFM images of topography image and phase image.
GPS data of Asian elephants were collected and analyzed with the remote sensing satellite photos of the region to estimate the landform physiognomy of different colors.
We also analyzed a series of ecological factors including altitude, landform, relief, villages and roads which affected the distribution and movement of Asian elephants.
In addition, how to divide ring zones in calculation and the errors caused by the inaccuracy of landform elevation and rock density has been quantitatively analysed.
In numerical experiments, this coordinate makes it possible to approximate a real relief at a high accuracy and to take into account specific features of a complex orography of the region.
In order to identify the sensitivity of the numerical simulation to the orography specification in a low resolution spectral model, two sets of numerical experiments for full-mountain and no-mountain cases are performed.
Experiments using a quasi-geostrophic model and theECMWF T21 spectral model with and without orography are performed to investigate the effects of mechanical forcing on the mean meridional circulation.
