摘要

在全球气候变化的背景下,长江流域发生了多次严重的高温干旱灾害,流域抗旱管理面临着旱情监测告警效率较低、旱灾预报预警精度不高、抗旱预案推演能力不足等瓶颈,迫切需要开展数字化转型。从长江流域抗旱减灾业务管理和“四预”应用需求出发,基于智慧水利和数字孪生建设的总体要求,综合运用WebGL、GIS等技术,建立了干旱防御数字孪生平台,研发了遥感干旱监测评估、干旱专业模型动态加载、旱警水位超限预警、抗旱预案可视化等关键技术,初步实现了“预报-预警-预演-预案”全链条贯通业务应用,切实提升了长江流域抗旱管理智能化、精细化水平,为流域干旱防灾减灾提供了技术支撑。

Abstract

In the context of global climate change, the Changjiang River basin has suffered from multiple severe high temperatures and drought disasters. Drought resistance management in the basin is faced with such bottleneck problems as low efficiency of drought monitoring and warning, inadequate accuracy of drought prediction and early-warning, and insufficient ability to deduce drought plans. To address these issues, digital transformation has become exigent. In line with the comprehensive requirements of smart water conservancy and digital twin technology, a digital twin platform for drought prevention has been constructed by utilizing WebGL and GIS to meet the operational management requirements of drought resistance and disaster mitigation in the Changjiang River Basin, aligning with the demands of the “forecast, early warning, preview, and contingency planning” principles. Key technologies have been developed, including remote sensing drought monitoring and evaluation, dynamic loading of drought-specific models, early-warning of water levels exceeding drought limit, and visualization of drought reduction plans. Consequently, the business application covering the full chain of “forecast, early warning, preview, and contingency planning” has been achieved. This has effectively improved the intelligent and refined level of drought resistance management in the Changjiang River Basin, providing technical support for drought prevention and disaster reduction in the basin.

摘要

2022年夏季长江流域发生了建国以来最为严重的干旱高温气候事件，对当地工农业生产、居民生活、生态安全等造成严重影响。为深入认识这次干旱高温气候事件发生的原因和改进气候预测技术，利用1951—2022年2400多测站气温、降水数据和NCEP/NCAR再分析数据等资料，采用T-N波作用通量、视热源Q<sub>1</sub>（Q<sub>2</sub>）诊断和合成分析、距平分析等方法，从大气环流异常的角度进行综合分析。主要结论如下：（1）2022年夏季，500 hPa源自北大西洋地区的扰动异常偏强，在沿中高纬西风带向东传播时引发了明显的大槽大脊活动，波动能量主要沿西风带向东传播，没有出现在东亚向东南方向传播的特征，造成冷空气活动位置偏北，很难影响到长江流域。（2）2022年夏季，500 hPa高度场在青藏高原上空出现明显正距平扰动，尤其8月扰动进一步加强，东移到长江流域，诱发西北太平洋副热带高压西伸，使得副热带高压呈现东西带状分布。副热带高压（简称“副高”）西部完全控制了长江流域地区，一方面副高阻挡了北方冷空气南下，另一方面副高长时间维持下沉运动，不利于降水发生，有利于下沉增温。（3）2022年夏季，热带对流区（视热源）位置异常偏南到赤道以南（气候态在5°N—20°N），有两方面影响：一是造成哈德来经圈环流（Hadley Cell）上升支异常偏南，长江流域在8月为异常下沉区，不利于降水发生，有利于下沉增温效应的出现；另一方面造成2022年夏季亚洲热带夏季风偏弱、东亚副热带夏季风偏强，低频信号向长江中下游传播明显偏弱，这些都不利于长江中下游降水过程的发生。（4）高纬、中低纬、低纬热带地区环流异常协同作用造成2022年长江流域夏季出现异常的干旱高温气候事件。要预测长江流域夏季降水或高温干旱，需提前关注500 hPa北大西洋地区扰动信号的发生及未来传播特征，青藏高原上空高度场扰动的发生及移动特征，热带对流（热源）位置变化及伴随的热带夏季风强度变化、低频信号的传播特征等。
