Seasonal Variation of the East Asian Subtropical Westerly Jet and Its Association with the Heating Field over East Asia

The structure and seasonal variation of the East Asian Subtropical Westerly Jet （EAWJ） and associations with heating fields over East Asia are examined by using NCEP/NCAR reanalysis data. Obvious differences exist in the westerly jet intensity and location in different regions and seasons due to the ocean-land distribution and seasonal thermal contrast, as well as the dynamic and thermodynamic impacts of the Tibetan Plateau. In winter, the EAWJ center is situated over the western Pacific Ocean and the intensity is reduced gradually from east to west over the East Asian region. In summer, the EAWJ center is located over the north of the Tibetan Plateau and the jet intensity is reduced evidently compared with that in winter. The EAWJ seasonal evolution is characterized by the obvious longitudinal inconsistency of the northward migration and in-phase southward retreat of the EAWJ axis. A good correspondence between the seasonal variations of EAWJ and the meridional differences of air temperature （MDT） in the mid-upper troposphere demonstrates that the MDT is the basic reason for the seasonal variation of EAWJ. Correlation analyses indicate that the Kuroshio Current region to the south of Japan and the Tibetan Plateau are the key areas for the variations of the EAWJ intensities in winter and in summer, respectively. The strong sensible and latent heating in the Kuroshio Current region is closely related to the intensification of EAWJ in winter. In summer, strong sensible heating in the Tibetan Plateau corresponds to the EAWJ strengthening and southward shift, while the weak sensible heating in the Tibetan Plateau is consistent with the EAWJ weakening and northward migration.

贵州省优质烤烟气候区划指标的补充和修正

从贵州省优质烤烟气候区划指标出发,结合威宁县高海拔地区种烟的实际情况,详细分析了贵州省优质烤烟气候区划指标。得出表征热量与作物生长发育的关系,不仅要考虑日平均温度和持天数,还要考虑积温、昼夜温差、地温及叶面温度等。通过分析,对原指标中成熟期平均温度。大田生长期温度、旺长－成熟期天数等指标进行了修正。补充≥１０℃活动积温≥２２００℃,移栽期日平均气温≥１４℃,月平均日较左≥８℃等指标。

门

题记:走出廉政那道门,就会迷失自己,踏上一条不归路。梅阳阳悄悄地被带走了,出房间门时那回望的眼神充满着无限惶恐和哀怜。那天,梅阳阳和朋友们正在饭店推杯换盏酒兴正酣。包间里灯火辉煌,轻歌妙曼,满室温馨。两个打扮休闲的人推开门后径直走到他面前亮了亮证件说:有个案件需要你配合调查一下,请随我们走一趟吧!梅阳阳一句话也没说就顺从地跟着走了。一天之后,各种传言接踵而至:有人说他利用职务大肆
