Problems solved by technology
[0006] The technical problem to be solved by the present invention is to solve the problem that there is no evaluation of the benefits of port meteorological services at present. This application proposes a benefit evaluation of port meteorological services from the aspects of disaster risk reduction and operation time extension. This evaluation method can quickly Intuitive, and can further display the importance of port weather service and the breakthrough of service

Embodiment
[0060] This embodiment provides a method for assessing the benefits of port meteorological services, such as figure 1 As shown, the method for assessing the benefits of meteorological services in this port includes the following steps:
[0061] S1: Calculate disaster risk reduction benefits;
[0062] The calculation of disaster risk reduction benefits includes calculating the comprehensive strength index of port hazard-causing factors and calculating the comprehensive vulnerability index of port hazard-bearing bodies;
[0063] The calculation of the port disaster-causing factor comprehensive strength index is determined by principal component analysis of the preset index data, and its expression is:
[0064] H=a*PC1+b*PC2 (1)
[0065] Among them: H is the comprehensive intensity index of port hazard factors; a is the variance contribution rate of the characteristic root of the first hazard factor, b is the variance contribution rate of the characteristic root of the second h...

The invention provides a method for assessing the benefits of port meteorological services, which is used to solve the problem that the comprehensive evaluation of port meteorological service benefits cannot be carried out at present. The method includes: calculating the disaster risk reduction benefit; the calculation of the disaster risk reduction benefit includes calculating the The comprehensive strength index of disaster factors and the calculation of the comprehensive vulnerability index of the port hazard-bearing body; the calculation of the comprehensive strength index of the port hazard-causing factor is determined by the principal component analysis of the preset index data; the calculation of the vulnerability index of the port hazard-bearing body through the emergence of the port hazard Determination of probability and damage rate of disaster-causing factors; calculation of operation time extension benefits; calculation of operation time extension benefits includes calculation of hourly output value of wharf and shipping company, calculation of total cost of port hourly output value, and calculation of shortened control time through port professional meteorological services ; By adopting this method, the benefit evaluation of the port can be carried out from the two aspects of disaster risk reduction and operation time extension, which is fast and intuitive, and can realize operationalization.
Description
technical field [0001] The invention relates to the technical field of weather service evaluation, in particular to a method for benefit evaluation of port weather service. Background technique [0002] The growing demand for professional meteorological services has brought great opportunities and challenges to the meteorological departments of coastal port cities. [0003] Weather has a serious impact on port production and operations. Common disastrous weather such as strong winds, sea fog, lightning, and typhoons have brought safety problems to normal channel passage and port operations. The impact of high-impact weather on ship travel and port operations can be divided into anchorage ship berthing, coastal waterway ship travel, ship entry and departure scheduling, and ship cargo loading and unloading, and different types of ships have different berthing high wind control standards. Due to different fog control standards in port areas, today's port and shipping operation...
