利用1979—2021年ERA5再分析资料,分析了盛夏西太平洋副热带高压(简称西太副高)北跳异常特征,研究了不同传播方向的热带大气低频信号对盛夏西太副高北跳异常的可能影响,探讨了西太副高北跳异常对我国东部地区夏季气候的影响。结果表明:盛夏期间,在西太副高北跳偏早年的北跳之前三候里,海洋性大陆地区和西太平洋低纬度地区的OLR场表现为异常的低频对流抑制逐渐北传和西北传,伴随着对流层低频非绝热加热负异常传播到副热带地区,从而在副热带到中纬度西北太平洋呈现出低频正位势高度异常,有利于盛夏期间西太副高北跳。在盛夏西太副高北跳偏晚年的北跳之前三候里,副热带西太平洋OLR为对流抑制异常的逐候增强并西北传,对应的对流层非绝热加热负异常也逐渐西北传,并激发出北太平洋上空的低频波列,该低频波列中的中纬度异常反气旋西移,有利于西太副高北跳。在盛夏西太副高北跳偏早年,我国长江以北地区更易出现极端高温,东北、黄淮和江南地区更易发生持续性强降水;在偏晚年,我国西南和江南地区更易出现极端高温,长江中下游地区更易出现强度更强的持续性强降水事件。

Based on observations of the equilibrium line altitude(ELA)of the Qiyi Glacier in the Qilian Mountain,we established a statistical model between ELA and its major influencing factors,warm season air temperature(air temperature averages for September,July and August)and cold season precipitation(total precipitation in the period January through March).Warm season air temperature was the leading climatic factor influencing ELA *** glacier ELA ascends(descends)172 m when warm season air temperature increases(decreases)by 1°C,and ascends(descends)62 m when cold season precipitation decreases(increases)by 10%.In the period 1958-2008,the glacier ELA showed a general increasing trend,ascending 230 m and reaching its highest altitude in 2006 at 5131 m a.s.l.,close to the glacier *** future climate is similar to that in the period 2001-2008,the Qiyi Glacier will not stabilize until it retreats by 2.08 km.

We report on the concentration and compositional features of n-alkanes of natural and anthropogenic origins in the snow samples collected from the Qiyi glacier in the Qilian Mountains, the Yuzhufeng glacier in eastern Kunlun Mountains, the Xiaodongkemadi glacier in the Tanggula Mountains, and the Gurenhekou glacier in the Nyainqêntanglha Range. The results indicate a decrease in the total n-alkane concentration (T-HCs) from the northeast to the south over the Tibetan Plateau. The T-HCs in these studied areas were close to those in the Belukha and Sofiyskiy glacier, Russian Alati Mountains and the Dasuopu glacier in the Himalaya but were much higher than those in the Greenland ice sheet, suggesting that the mountain glaciers in the Asian continent may receive a higher loading of n-alkanes than the Greenland ice core. Moreover, the compositional characteristics of n-alkanes indicated that the n-alkanes in the studied areas were probably originated from the plant waxes as well as the fossil-fuel combustion exhaust, whereas the contribution from the lower organisms was small. In addition, the plant wax (Cn(wax)) and anthropogenic (non-Cn(wax)) contributions revealed that fast industrialization may have significant effects on the organic pollutant composition in glacier over the Tibetan Plateau and its circumference environment. Particularly, except for the Yuzhufeng glacier, the ΣnC21-/ΣnC22+ and (nC15+nC17+nC19)/(nC27+nC29+nC31) ratio decreased from the Qiyi glacier to the Gurenhekou glacier over the Tibetan Plateau, while the carbon preference index (CPI) values increased. These results indicate a decrease in terrigenous input while an increase in marine input from the northeast to the south over the Tibetan Plateau. These two ratios can be used as the climatic and environmental change indicators.

Based on the data of δ18O in precipitation during the period of April 2006 through May 2007 in the upper catchment of the main stream of the heihe River in the Qilian Mountains, we found that there existed an evident altitude effect on δ18O in precipitation, and the δ18O-altitude gradient was _0.18‰/100 m. When δ18O in river water at the outlet of the mountainous drainage area of the main stream of the heihe River was combined with the δ18O-altitude relation, it was realized that the mountainous runoff was generated mostly at high altitudes. Using two component models, we revealed that 80.2% of the annual total mountainous runoff amount was generated at the alpine permafrost-snow-ice zone with an altitude of above 3600 m a.s.l.

目的:比较黄芩与生姜配伍前后对湿热模型大鼠胃肠功能的影响,探究两药“相恶”内涵。方法:将50只SD大鼠随机分成正常组、模型组、黄芩组,不同配比黄芩生姜组(1∶1及2∶1),每组10只。采用复合因素法制备大鼠胃肠湿热模型,造模成功后连续7天给予相应药物灌胃,每日1次;取材后,苏木精-伊红染色法(hematoxylin-eosin staining,he)观察各组大鼠胃、结肠组织病理学形态变化情况;计算大鼠胃内残留率;硝酸还原酶法检测大鼠血清一氧化氮(nitric oxide,NO)水平;酶联免疫吸附试验(enzyme linked immunosorbent assay,ELISA)测定各组大鼠血清肿瘤坏死因子α(tumor necrosis factor α,TNF-α)、白细胞介素10(interleukin-10,IL-10)等炎症因子表达水平;ELISA法检测胃及结肠组织神经肽P物质(substance P,SP)、血管活性肠肽(vasoactive intestinal peptide,VIP)、生长抑素(somatostatin,SS)、胃泌素(gastrin,GAS)等胃肠激素含量。结果:干预后,与模型组比较,黄芩组、黄芩生姜1∶1组大鼠胃残留率降低(P0.05)。结论:黄芩水煎液、黄芩生姜1∶1水煎液能改善湿热大鼠胃肠功能状态,主要通过调节胃肠激素、炎症因子水平发挥作用,且黄芩生姜2∶1配伍时,两药相恶减效,清热燥湿作用减弱。
