Operational Practice and Thinking on Early Warning of Agrometeorological Disaster Risk of Winter Wheat
Risk early warning of agrometeorological disaster of winter wheat is one of the most impor-tant tasks to ensure wheat production safety and reduce disaster losses.Since 2022,operational service work of agrometeorological disaster risk early warning has been carried out jointly by the meteorological department and the agriculture department,and some technical achievements and successful cases have been achieved,but there are also some problems and deficiencies.In this paper,we briefly described the operational service connotation of agrometeorological disaster risk early warning,proposed the disaster possibility prediction,hazard and vulnerability estimate,and built the technical framework of agrometeo-rological disaster risk warning operational service of winter wheat based on the risk matrix.Moreover,taking the early warning of wheat dry-hot wind risk in 2022 as an example,we displayed the technical process of agrometeorological disaster risk early warning of winter wheat.The operational service work of agrometeorological disaster risk early warning of winter wheat has just started,a lot of work still needs to be done,including how to deeply integrate with the existing disaster risk assessment results,carry out quantitative disaster impact forecast and make quantitative early warning index calibration.In addition,a lot of research and development work is needed in improving the accuracy of early warning of agrometeo-rological disaster risk of winter wheat and evaluating the service benefits.
