广东省冬季逐日最低气温的预报方法

为了能结合数值预报产品做好广东省逐日最低气温的预报,利用1998~2007年冬季(11月~次年2月)美国NCEP/NCAR再分析资料和常规气象观测资料,选取20°~27.5°N,107.5°~117.5°E区域内的海平面气压、850 hPa温度、850 hPa相对湿度、850 hPa纬向风(u)、850 hPa经向风分量(v)和500hPa位势高度等6个要素作为预报因子,以韶关、梅州、广州、阳江、汕头等5个站分别作为广东5个部分的代表站,采用能选取"最优"因子的逐步回归方法建立5个代表站的11月~次年2月逐日的最低气温预报方程,并对预报方程进行检验。结果表明:采用逐步回归预报方法建立的广东省5个代表站的逐日最低气温预报方程具有一定的预报能力,但也存在预报结果比实况偏低的不足。     

VARIATION OF PRECIPITATION DURING WINTER AS A CAUSE OF SUSTAINED DROUGHT IN GUANGDONG DURING THE PAST 50 YEARS

The variation characteristics of precipitation during the winter (between October and the following March, to be referred to as just “the winter” hereafter) in Guangdong province during the past 50 years (from 1957 to 2006) and the relationship with Pacific SST are studied using the methods of Empirical Orthogonal Function (EOF) analysis, wavelet analysis, and correlation analysis. The results show that The Guangdong precipitation during the winter exhibits quasi-periodic significant oscillations of 40 years and 2 years; rainfall is less from the end of the 1950s to the start of the 1970s and from the end of the 1990s to the present than from the mid 1970s to the mid 1990s. The frequency of sustained drought is more than sustained flooding during the winter. The Guangdong precipitation during this time period is in significantly positive correlation to the equatorial central and eastern Pacific SST, but in a significantly negative correlation with the western and northern Pacific SST east of the Philippine Sea. 61.5% of the sustained drought occurred in the phase of negative anomalies of the Ni?o3.4 index and 38.5% in the phase of positive ones. A composite analysis of atmospheric circulation is performed for the positive and negative phases of the Ni?o3.4 region associated with the sustained drought. The results showed that a weak polar vortex, a strong trough in Europe and a ridge near Balkhash Lake, active cold air and consistent northerly wind anomalies controlling Guangdong at low levels, an inactive westerly low disturbance in the low-mid latitude of the Asian continent, and a weak southern branch westerly trough, are all mutual causes for the sustained drought.     

Organically geochemical characteristics of the Fankou Pb-Zn deposit in North Guangdong Province, China： Implication for Pb-Zn enrichment

The Fankou Pb-Zn deposit is a very important and famous deposit in China. The time of Pb-Zn enrichment has been debated for a long time in this deposit. A total of seventeen samples of three sections were taken from the Fankou mine for the study of mineralization time and the mechanism of ore formation. The samples were analyzed by microscope, Soxhlet-extract, GC, and GC/MS methods. The results indicated that organic bulk parameters vary with the Pb-Zn contents in different samples and clearly were influenced by ore sulfide formation. Organically geochemical parameters (MPI 1, CPI) indicate that the paleotemperatures in the Fankou deposit are lower than 80°C in all three sections. Sulfides in the wall rocks might occur mainly during synsedimentation or early diagenesis by BSR or partly by PR, rather than by TSR at such low temperatures, this stage may be the first mineralization stage. Sulfides near the faults might be formed by TSR after sedimentation, this stage may be the second mineralization stage.
