CLIMATIC ANALYSIS OF IMPACTS OF THE TROPICAL CONVECTION IN WESTERN PACIFIC ON WESTERN PACIFIC SUBTROPICAL HIGH’S SHORT-TERM SCALES DURING BOREAL SUMMER*

Based on the multi-year average NCEP/NCAR reanalysis data and NOAA's OLR data,the climatic characteristics of the tropical convection in tropical western Pacific and Indian Oceans as well as its relationship with western Pacific subtropical high (WPSH) is shown as follows:on short-term scales,the tropical convection that has significant influence on western Pacific high's latitudinal movement is located in the area of the South China Sea to the Philippines,which is the 2-day precursor prior to WPSH's latitudinal fluctuation,that is,WPSH is shifting to north 2 days after the tropical convection becomes more active,and vice versa.Moreover,the tropical convection has less effect on WPSH's longitudinal movement.     

洛坝铅锌矿床的构造演化分析

洛坝铅锌矿床位于黄诸关韧脆性变形带所波及的范围内,断裂、褶皱、劈理、节理等形态构造类型均很发育,经对小型构造的统计及应力场分析证明,矿区变形主要是在海西—印支期长期存在的南北向古应力场持续作用下形成的。     

On a new species ofPavlova (Prymnesiophyceae) from China

Pavlova viridis sp. nov. is described on the basis of light and electron microscope observations. The material was collected from the coast of haiyang county of Shandong, China. It is characterized by 1) yellowish green to green chloroplast, 2) rudimentary short flagellum 0.3 μm long and hook-shaped, 3) long flagellum with small spherical knob-scales, 4) absence of pyrenoid and stigma, and 5) marine habitat. This new species andP. salina seem to be most closely related to each other but their colour, the insertion of their three appendages, the shape of their knob scales, and their cell periplasts are quite different from one another.

A NEW SPECIES OF THE GENUS NEROCILA （ISOPODA： CYMOTHOIDAE） FROM THE EAST CHINA SEA

A new species of cymothoid Isopeda, Nerocila donghaiensis, collected from the body of a sciaenid fish, Johnius sp., is described in the present paper. The new species can be distinguished from the other species of genus Nerocila by its endoped of uropods with deep notch, sharply serrated on the lateral margin and strongly serrated on the medial margin; antennule with 1 st article swollen; dactyli of pereopods Ⅰ, Ⅱ, Ⅳ, Ⅴ swollen.
