河北省地形复杂,夏季多发生短时强降水和暴雨等强对流天气。有必要利用GNSS水汽开展短时天气预报研究。该文首先利用河北省CORS网2013年5-8月GNSS站点数据和气象数据开展了GNSS水汽与实际降水的比较,然后依据6次降水过程中GNSS PWV及GNSS△PWV的变化来探测河北省夏季水汽通道。研究发现:接近60%的GNSS水汽序列峰值超前于实际降水,可利用测站GNSS水汽变化进行降水预报。GNSS PWV的空间变化趋势与水汽通道的方向一致,证实了河北省夏季存在西北-东南方向和西南-东北方向两条水汽通道。研究结果可为河北省短时强降雨的预报提供参考和借鉴。

行为人取得财产是否获得占有主体的同意,能够有效解决新型支付方式侵占行为中“盗骗交织”的困境。运用“预设的同意”处理财产犯罪,关键在于判断同意(占有)主体以及同意条件的范围。第三方支付平台资金可分为账户内资金和账户绑定的银行卡资金,根据占有的事实支配,前者属于第三方支付机构占有,后者属于银行占有。占有主体的同意是客观的,体现在程序的身份识别规则中。“取款人身份”不属于同意条件,应认为是同意的动机。冒用他人第三方支付账户转移资金的行为属于诈骗行为,根据不同的资金性质成立不同的诈骗类犯罪。
