云龙台固体潮观测对地震监测能力的评价

对云龙台的水管倾斜仪观测数据进行了倾斜固体潮的潮汐分析，发现ＥＷ和ＮＳ两个分量的振幅因子异常变化与地震有较好的对应关系。由于潮汐分析方法本身的科学性和严密性，故振幅因子误差小、精度高；又因为对潮汐谐波波群的选择，避免了以太阳日为基础的周期性干扰，Ｍ２、Ｏ１波振幅因子的地震异常识别则简易可行，并且可信度高。云龙台的固体潮观测具有较强的地震监测能力。     

Remote sensing-modelisation approach for diurnal estimation of burnt biomass in the Central African Republic Savanna

Experimental studies and mesoscale modeling of atmospheric chemistry require a good knowledge of the sources of the atmospheric constituent, at a temporal scale of about one hour and at a spatial scale corresponding to the model grid. A combined remote sensing/modeling approach for the estimation of the diurnal distribution of the amount of biomass burning in Central African Republic (C.A.R.) savanna fires is proposed. The fire propagation model (BEHAVE) developed by Rothermel was adapted to the fuel characteristics encountered in C.A.R. Ground and airborne measurements with satellite images (NOAA/AVHRR) were used to predict an accurate estimate of the burnt biomass. This combination allows the calculation of the distribution of the number of fires during the day providing an evaluation of the instantaneous fluxes of the compounds emitted in the atmosphere by these fires.     

Comparison of observed and theoretically calculated seiches of Heda Bay,Japan

We carried out observations of sea-level fluctuations simultaneously at three stations on the coast of Heda Bay, Honshu, Japan, using supersonic-type water level gauges controlled by a personal computer. Analyses of the obtained data showed predominant spectral peaks at periods of 7.6, 2.0 and 1.3 minutes for all three stations. Comparison of the observed data with numerically calculated normal oscillation modes of the bay indicates that these three spectral peaks correspond to the theoretical first, third and seventh normal modes of the basin respectively, judging from the results of cross-spectral analyses. The reason for the absence of the remaining normal modes, especially of the second or the lateral first mode of the basin, is briefly considered.

逆气压改正对卫星测高数据反演潮汐参数的影响

定量分析了逆气压改正对各主分潮潮汐参数反演的影响。结果表明,逆气压改正对Sa的反演结果影响最大,在Sa的实际振幅中,气压变化的平均贡献比率为42%,气压变化使Sa的迟角减小了约27°,而对其他主分潮的影响可忽略不计。建议在应用卫星测高数据时,不加逆气压改正,但在数据处理时,需加Sa分潮的改正。
