    • 摘要: 基于2000—2019年99个地面观测站记录的冰雹数据及ECMWF提供的ERA5各项参数月平均数据,结合线性回归、5 a滑动平均等方法,分析了陕西省冰雹变化特征及关键影响因素。结果表明:(1)陕西省冰雹次数在地理位置上呈现由南到北增加的特征,海拔高度与年平均冰雹次数在低海拔表现出显著的正相关关系。(2)陕西省冰雹受季节影响程度呈现由南到北增强的特征,其中陕北、关中冰雹次数夏多冬少,陕南冰雹次数各季节相对平均。(3)陕西省年际冰雹次数整体呈下降趋势,其中陕北地区下降速度最快,关中地区其次,而陕南地区年际变化无明显变化趋势。(4)对流有效位能(CAPE)对陕西省冰雹年际趋势起主导作用;K指数对陕北夏季、关中春季冰雹次数变化趋势起主导作用;0°C层高度对关中夏、秋季与陕南春、夏季冰雹次数变化趋势起主导作用。

    • 摘要: Coastal marine boundary layer jets(CMBLJs)play an important role in coastal and inland rainfall in South China.Using 21 years of ERA5 and CMORPH rainfall data,two main CMBLJs are found,one on each side of Hainan Island(named BLJ-WEST and BLJ-EAST),which are always strengthened jointly.Both CMBLJs often occur in the pre-summer rainy season and exhibit an evident diurnal cycle with a maximum at night.With the emergence of the CMBLJs,rainfall is significantly enhanced in South China,particularly downstream of each CMBLJ.The response of rainfall to the CMBLJs is mainly attributed to convergence at the terminus of each CMBLJ,terrain-induced lifting,and relevant atmospheric stratification.Coastal rainfall downstream of the BLJ-WEST is much weaker than that downstream of the BLJ-EAST because of higher CIN over the Beibu Gulf,which is caused by lower temperature lapse rates and adiabatic heating in the lee of the Annamite Range.The inland rainfall increases along with CMBLJ intensity,whereas coastal rainfall reaches a maximum in the presence of moderate CMBLJs rather than stronger CMBLJs.Stronger CMBLJs induce stronger dynamic lifting but higher CIN near the coastal area.Additionally,CAPE near the coast does not become highest with strongest CMBLJs,because the CAPE generation contributed by coastal dynamic lifting can be offset by the negative contribution caused by the horizontal advection of cold and dry air from the Indochina Peninsula.Therefore,anomalous dynamic lifting,moisture flux convergence,and CAPE/CIN associated with CMBLJ intensity jointly result in anomalous rainfall.

    • 摘要: 【目的】探究咖啡酸苯乙酯(caffeic acid phenethyl ester,CAPE)通过AMPK/FOXO3a信号通路缓解氧化应激对猪精液的影响及其分子机制。【方法】选取8头成年(1—2岁)、健康状况良好长白种公猪进行鲜精采集,将质检合格的样品混池待用。试验设计如下:首先,在常温基础稀释液中分别添加0、0.02、0.04、0.06、0.08和0.10 g·L^(-1)浓度的CAPE,将精液样品与各个浓度组依次混合后放置室温平衡,随即转入17°C电子恒温冰箱进行常温保存。全自动精子分析仪(CASA)测定1—5 d精子运动学参数(总活率与渐进性活力),筛选出最佳适宜浓度为0.06 g·L^(-1)。其次,将0.06 g·L^(-1) CAPE与400μmol·L^(-1)的H_(2)O_(2)建立氧化胁迫模型,在第1、3、5天分别采用CASA测定精子总活率与渐进性活力,荧光探针技术评估质膜完整性与顶体完整性,抗氧化试剂盒检测过氧化氢酶(catalase,CAT)与超氧化物歧化酶(superoxide dismutase,SOD)活性,在第5天利用实时荧光定量PCR技术测定AMPK/FOXO3a信号通路下游靶向基因(AMPK、FOXO3a、SOD1、SOD2、CAT)及凋亡基因BAX的mRNA表达水平,蛋白免疫印记技术测定AMPK、p-AMPK蛋白表达。【结果】(1)浓度筛选试验中,0.06 g·L^(-1)的CAPE在保存第3天显著提高精子的总活率并维持至第5天(P0.05)。与CAPE+H_(2)O_(2)混合组相比,H_(2)O_(2)处理组AMPK、FOXO3a、SOD1、SOD2、CAT的mRNA表达水平显著降低(P0.05)。在蛋白表达水平中,CAPE+H_(2)O_(2)混合组与H_(2)O_(2)组相比,AMPK、p-AMPK与p-AMPK/AMPK比率显著提升(P<0.05)。【结论】在常温基础稀释液中添加0.06 g·L^(-1)CAPE可通过促进磷酸化AMPK的表达,诱导AMPK/FOXO3a信号下游抗氧化分子的转录,继而缓解H_(2)O_(2)介导的氧化危害对精液品质产生的影响,延长精液的保存时间,但CAPE保护精子氧化损伤更为深入的分子机制仍需作进一步探究。

    • 摘要: 2022年5月27日乌鲁木齐机场出现了一次中雷雨天气过程,对机场和终端区多个航班造成较强影响。本文利用常规观测资料、机场自动观测资料、NCEP再分析资料、微波辐射计资料、多普勒雷达资料对此次强对流天气进行诊断分析,初步探讨此次强对流天气的形成机制。结果表明:1) 强对流发生前夕,中低层存在切变线和水平风的垂直切变。2) 中低层的对流不稳定为强对流过程提供了不稳定条件。3) 午后云量的增加使中层水汽不断汇集,为雷暴的发生提供水汽条件。4) 从各类指数分布看,乌鲁木齐周边累积了大量不稳定能量,在大尺度强迫作用下克服了对流抑制而产生了对流。5) 微波辐射计资料中的液态水含量针对此次雷雨有较好的对应。

    • 摘要: 面对可能出现的强天气,气象预报员关注的重点往往是那些天气形势表现明显、大气环境特征表现强烈的重大天气过程.而对前期大气环境特征偏弱或者不太强烈的天气过程则通常会有所忽视.在一些特有的天气背景下,弱的大气环境中经常会蕴藏着强天气出现的可能性,而这一类型的天气过程更加是气象预报员分析和总结的重点内容之一.

    • 摘要: Purpose: MCF-7 (ER+, WTP53) and MDA-MB-231 (ER Met, Mutant P53) Caffeic Acid Phenethyl Ester (CAPE) and DNA Methyl Transferase Inhibitor (DNMTi) in breast cancer cell lines of Zebularine (ZEB) single and combined application of TP53, caspase-9, caspase 8 and caspase-3 genes as a result of the use of single and combined drug methylation profiles are aimed to be evaluated by specific PCR method. Material-Metods: In the MCF-7 and MDA-MB-231 breast cancer cell lines, MTT test and survival analysis were performed as a result of single and combined application of CAPE and Zebularine and Methylation Specific PCR was performed to examine the methylation of caspase-3, caspase-8, caspase-9 and TP53 genes. Results: According to the results of 24-hour drug administration, the IC50 for the MCF-7 cell line was determined as 200 μM, for CAPE 40 μM and for the combined values of 50 μM ZEB + 5 μM CAPE. The effects of caspase-3, caspase-8, caspase-9 and TP53 genes on the methylation level of ZEB, CAPE and ZEB + CAPE drug combination were determined by using bisulfite modified DNAs in MCF-7 and MDA-MB-231 cell lines. Discussion: In the MCF-7 cell line, the 120 μM ZEB viability rate was 51%, and the viability of 80 μM ZEB MDA-MB-231 breast cancer cells decreased by 59.7%. After 20 μM CAPE, viability in MCF-7 cells decreased by 31% in 120 μM CAPE and MDA-MB-231 cells decreased by 41%. The viability with 40 μM CAPE decreased by 19% in MDA-MB-231 cells. It was found that 20 μM CAPE concentration was associated with TP53 methylation in MCF-7 cell lines. The 80 μM ZEB concentration was found to be closely related to the unmethylated status of the TP53 gene. These results obtained with 50 μM ZEB + 5 μM CAPE application were found to be related to the methylated-unmetylated status of the TP53 gene in half (50%). For the caspase-9 gene of MDA-MB-231 cells, 80 μM ZEB concentration was found to be associated with unmetylated status. The effective use of drugs with low concentrations of the drug dose provides a more appropriate approach in terms of treatment.

    • 摘要: Summer monsoon and its synoptic, meso-scale systems provide 80% of total annual rainfall over India. Monsoon depressions are weak, low-pressure circulation within the monsoon trough that forms in the head Bay of Bengal and moves northwestward and westward across the Indian sub-continent during summer monsoon season. Another convective system from this planetary scale circulation is the Intraseasonal Oscillation (ISO) also occurs in the daily mode. It is very important to study the impact of monsoon depressions in synoptic scale on ISOs through its strength, frequency and duration. In the recent decades, frequency of monsoon depressions and sea surface temperature over head Bay is decreasing while the intensity is increasing over Bay of Bengal. The study brings out the relationship between the ISOs and monsoon depressions over Bay of Bengal through their structure and movement for the period 1990-2014. Composites of monsoon and no monsoon depression days are calculated and found that rainfall is mainly occupied over Kerala and Interior Peninsula within the range of 10 - 50 cm during monsoon depression days. Relative vorticity brings out that the shallower layer of convergence mainly from 1000 - 850 hPa level and a deeper layer of weak divergence above it is mainly associated with the depression. Next, thermodynamic structure of monsoon depression and its intensity is directly proportional to the increasing of CAPE. Wavelet spectrum also indicates the intraseasonal oscillations are very active during monsoon depression days. Finally this study helps to bring out plausible reasons through circulations, dynamic and thermodynamic characteristics involved in monsoon depression days in association with the ISOs.
