Water vapor is a highly variable parameter in atmospheric processes and it plays a crucial role in atmospheric motions on a wide range of scales in space and time. GPS technique has been widely used in retrieving precipitable water vapor. Firstly the article has retrieved precipitable water vapor of Qinhuangdao and Shijiazhuang stations by GPS technique. Then it has researched two aspects of precipitable water vapor. One is the spatial and temporal distribution characters of precipitable water vapor;the other is the relation between precipitable water vapor and actual rainfall. The value of GPS precipitable water vapor of Shijiazhuang is higher than the value of GPS precipitable water vapor of Qinhuangdao, which is accord to the formula that the precipitable water vapor is reduced from south to north. During the different time of a day, there are differ degree fluctuate which the min value present to morning and the max value present to evening. It also compared the GPS precipitable water vapor and actual rainfall. Although the time of max value about rainfall is not identical to the time of max value about precipitable water vapor, rainfall has occurred mostly in the time while the value of precpitable water vapor is high.

Adsorption Mechanism and Kinetic Characterization of Bituminous Coal under High Temperatures and Pressures in the Linxing-Shenfu Area

Acta Geologica Sinica(English Edition) 2020年第2期94卷 399-408页

The majority of coalbed methane(CBM) in coal reservoirs is in adsorption states in coal matrix pores. To reveal the adsorption behavior of bituminous coal under high-temperature and high-pressure conditions and to discuss the microscopic control mechanism affecting the adsorption characteristics, isothermal adsorption experiments under hightemperature and high-pressure conditions, low-temperature liquid nitrogen adsorption-desorption experiments and CO2 adsorption experiments were performed on coal samples. Results show that the adsorption capacity of coal is comprehensively controlled by the maximum vitrinite reflectance(Ro, max), as well as temperature and pressure conditions. As the vitrinite reflectance increases, the adsorption capacity of coal increases. At low pressures, the pressure has a significant effect on the positive effect of adsorption, but the effect of temperature is relatively weak. As the pressure increases, the effect of temperature on the negative effect of adsorption gradually becomes apparent, and the influence of pressure gradually decreases. Considering pore volumes of pores with diameters of 1.7-100 nm, the peak volume of pores with diameters 10-100 nm is higher than that from pores with diameters 1.7-10 nm, especially for pores with diameters of 40-60 nm, indicating that pores with diameters of 10-100 nm are the main contributors to the pore volume. The pore specific surface area shows multiple peaks, and the peak value appears for pore diameters of 2-3 nm, indicating that this pore diameter is the main contributor to the specific surface area. For pore diameters of 0.489-1.083 nm, the pore size distribution is bimodal, with peak values at 0.56-0.62 nm and 0.82-0.88 nm. The adsorption capability of the coal reservoir depends on the development degree of the supermicroporous specific surface area, because the supermicroporous pores are the main contributors to the specific pore area. Additionally, the adsorption space increases as the adso

Retrieval of the Change of Precipitable Water Vapor by GPS Technique

Geo-Spatial Information Science 2007年第4期10卷 265-268页

作者： wang yong LIU Yanping LIU Lintao XU Houze college of traffic and surveying Hebei Polytechnic University 46 West Xinhua Road Tangshan 063009 China

The feasibility of GPS precipitable water vapor （PWV） is discussed based on the comparison of Radiosonde and GPS PWV where the correlation coefficient is 0.94 and the RMS is 4.0 mm. PWV change in the Chinese mainland in 2004 is graphed with the gridding method of splines in tension, according to the GPS data of the crust monitor observation network in China, combined with relevant meteorology information. According to the distribution of the annual amount of rainfall in the country, it can be concluded that the total trend of the PWV is diminishing from the south-east coastland to the north-west inland. The PWV reaches its maximum during July and August, and the minimum is reached during January and February. According to the PWV, from high to low, all districts can be ranked as south-east coastland, the inland and the tableland.

In view of the usefulness of Empirical Mode Decomposition （EMD）, Artificial Neural Networks （ ANN）, and Most Relevant Matching Extension （MRME） methods in dealing with nonlinear signals, we pro- pose a new way of combining these methods to deal with signal prediction. We found the results of combining EMD with either ANN or MRME to have higher prediction precision for a time series than the result of using EMD alone.

GPS-Meteorology Network in Wuhan Region

引用

Geo-Spatial Information Science 2008年第2期11卷 139-142页

作者： wang yong LIU Yanping XU Hong HU Xiaogang LIU Lintao XU Houze college of traffic and surveying Hebei Polytechnic University 46 West Xinhua Road Tangshan 063009 China 不详

There are three aspects in the study of GPS meteorology network in the Wuhan region. The first is the comparison of the GPS precipitable water vapor between final ephemeris and ultra-rapid ephemeris for which the relative coefficient is 99.97 and the root mean squares is 0.048 mm. It can be concluded that ultra-rapid ephemeris can be used to get the GPS precipitable water vapor for the real-time prediction. The second is the comparison of precipitable water vapor of GPS stations and the distribution of water vapor in the Wuhan region is acquired. The change of GPS precipitable water vapor and rainfall in a rainfall process are compared and analyzed. The change of GPS precipitable water vapor can reflect and predict the process of rainfall.
