摘　　要：气候监测诊断是了解气候系统变化及其成因的重要手段。经过二十多年的发展,目前国家气候中心建立了一套多时间、多空间尺度的气候系统监测诊断业务系统,并且在业务应用中不断发展和完善。同时,加强了关键异常信号及其对我国气候异常的影响机理的研究,在海温、冰雪、±壤温湿度、大气低频振动、北极涛动、季风、平流层异常等对我国气候影响的监测诊断等方面提出一些新理论、新技术和新方法,并在业务中得以应用。本文回顾了近20年来我国气候监测诊断业务的发展历程,介绍了我国气候监测诊断业务的技术现状,重点总结了近些年来在实时气候监测诊断业务中发展和应用的一些新技术和气候异常机理。Climate monitoring and diagnosis is an important method to know about the changes of climate system and their causes, playing an important role in climate operation. The history and current status of the cli- mate monitoring and diagnosis operation in China are reviewed and some new technologies, methods and mechanisms developed and applied in operation in recent years are introduced. In 1990, the operational system of monthly climate monitoring is established in China for the first time. After the developments of more than 20 years, the climate monitoring and diagnosis operation in China makes great progresses in the aspects of theory, method, technology, and operational system, which go through the stages from the simple analysis of station observations to the monitoring of the mul- tiple layers of climate system and the dynamic diagnosis of climate anomalies. At present, a set of climate monitoring and diagnosis operation system on multiple temporal and spa- tial-scales is set up and continuously improved, and some new theories, technologies, and approaches are promoted and applied. In the aspect of atmospheric circulation, besides basic characteristic variables relat- ed to height, wind and so on, the monitoring and diagnosis operational products of stratospheric process, northeast cold vortex, Walker circulation, Hadley circulation, water vapor transportation are also devel- oped. Furthermore, the monitoring and diagnosis operation of the extreme weather and climate events over China and the world is gradually set up and improved. In the aspect of ocean, besides the physical system in the tropical and extra-tropical ocean and atmosphere related to ENSO, the monitoring and diagnosis technologies and products in light of the sda temperature anomalies of Indian Ocean and Atlantic Ocean with the major modes of oceanic and atmospheric system are developed. In the aspect of sea ice and snow, the monitoring and diagnosis technologies and products of the Antarctic and Arctic sea ice concentration and days as well
