| 1 | 探空仪湿度测量误差研究现状及其对云识别的影响显示文摘探空湿度观测是获取湿度资料的重要手段,探空仪湿度传感器的性能会直接影响湿度的测量结果并对基于探空湿度资料识别的云层准确性造成影响。为更好地了解目前国内外探空仪湿度测量的准确性,回顾了大量国内外研究成果,简要介绍了国内外探空仪的类型及湿度传感器性能,归纳了探空仪湿度测量误差并探讨了湿度测量误差对云识别的影响。分析发现,探空仪湿度测量误差来源多样,是多种因素综合作用的结果。一般而言,在对流层低层温度较高的条件下,湿度测量的结果较为准确,云层识别较为可靠;但湿度传感器在低温条件下响应时间变长、灵敏度下降,导致云底的识别准确性要高于云顶,而识别的中、高云偏少;而高湿条件下,测湿元件易被沾湿,导致湿度异常偏高,从而使得识别的云层偏厚;探空仪普遍存在湿度异常偏低的情况,尤其是湿度较高的测站,从而导致云层漏判。 | 孙丽 赵姝慧 | 2018 | 地球科学进展2018，33，1： | 7 |
| 2 | 东印度洋海洋学综合科学考察航次概况显示文摘赤道东印度洋海域是西半球暖池的重要组成部分,对我国季风系统乃至全球气候变化研究意义重大.印度洋作为海上丝绸之路的交通要道,开展东印度洋海洋调查也是保障海上丝绸之路安全的重要一环.自2010年起,国家自然科学基金委为贯彻落实《国家自然科学基金'十一五'发展规划》的战略部署而设立的'国家自然科学基金委印度洋综合航次',极大地促进了海洋学科多学科交叉和融合,丰富了该海域的海洋观测数据,取得了丰硕的科研成果.本文介绍了2010年起至今的东印度洋海洋学综合科学航次考察的内容、进展和成果,并展望了东印度洋海洋学综合科学考察航次今后的主要方向. | 梁湛林 何云开 李健 陈荣裕 隋丹丹 张镇秋 谢强 陈举 | 2018 | 南京信息工程大学学报(自然科学版)2018，10，3： | 3 |
| 3 | Statistical characteristics of the surface ducts over the South China Sea from GPS radiosonde data显示文摘Based on the global position system(GPS) radiosonde data near the sea surface, the surface duct characteristics over the South China Sea(SCS) were statistically analyzed. The annual surface duct occurrence over the SCS was about 64%. Of the observed surface ducts, duct heights mainly distributed between 18 and 42 m, with M slopes in the range of –0.3 to –0.2 M units/m. Those ducts accounted for about 80% of the ducting cases. For the total profiles, the duct occurrences in a day changed slowly and were more than 60% in all times. The surface ducts formed more easily in the daytime than in the nighttime and most of the duct height were at bellow about 32 m.Additionally, The seasonal variation of the SCS ducts appeared to be evident, except that the mean duct thickness was almost constant, about 33 m for all seasons. The highest occurrence was about 71% in the autumn, followed by in the summer, spring and winter. In spring, their top-height existed more often at a height of more than 48 m.Their mean duct strength became stronger trend from spring to winter, with the M-slope in the range between–0.26 and –0.18 M units/m. Those results agreed well with other studies, provided considering the data resolution.The statistical analysis was reliable and gave the duct estimation for the SCS. Such duct climatology not only has important implications for communication systems and the reliability of the radar observation, but also can provide useful information to improve the accuracy of the meteorological radar measurements. | CHENG Yinhe ZHOU Shengqi WANG Dongxiao LU Yuanzheng YAO Jinglong | 2015 | Acta Oceanologica Sinica2015，34，11： | 2 |
| 4 | 基于高空气球平台的下投探空:系统研发和青藏高原实验显示文摘为提高复杂地理环境和极端天气条件下的大气廓线探测能力,本文自主研发了基于平流层高空气球平台的下投探空系统,并在青藏高原开展探测评估实验.该系统主要由下投探空舱,携带降落伞的下投探空仪,下投施放装置,数据接收通讯天线和GPS模块等组成.下投探空仪测量数据通过卫星通信链路和无线电信号实时发送至数据接收机存储处理.2020年青藏高原实验中8枚下投探空仪全部成功施放,提供了合理有效的大气廓线探测数据.后续会进一步提高下投探空仪传感器性能,全面评估其探测准确性和精度. | Jinqiang Zhang Hongbin Chen Yunfei Du Wenzheng Shao Runping Zeng Keping Zhu Yi Liu Yuejian Xuan | 2021 | Atmospheric and Oceanic Science Letters2021，14，3： | 0 |
