具体实施方式detailed description
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步的详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定发明。In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the invention.
下面结合附图对本发明的结构和应用原理作详细的描述。The structure and application principle of the present invention will be described in detail below in conjunction with the accompanying drawings.
如图1所示，本发明实施例的气候事件风险评估方法包括以下步骤：As shown in Figure 1, the climate event risk assessment method of the embodiment of the present invention includes the following steps:
利用该地区近来的地面常规观测、自动气象站点以及卫星雷达资料(例如降水、气温、风速、高度场等)，建立强对流天气个例数据库，并实时添加最新观测资料入库；对历史上该地区的强对流天气进行统计分析，得出该地区强对流天气特征；利用上述研究确定各类天气预警预报的参数和阀值，建立V-3Theda预报预警模型，开展强对流天气监测、预警预报工作，所得信息以文字、图表等形式对使用者及时发布。Using recent ground routine observations, automatic weather stations, and satellite radar data (such as precipitation, temperature, wind speed, height field, etc.) in this area, establish a strong convective weather case database, and add the latest observation data into the database in real time; Statistical analysis of strong convective weather in the region, to obtain the characteristics of strong convective weather in the region; use the above research to determine the parameters and thresholds of various weather warnings and forecasts, establish the V-3Theda forecast and early warning model, and carry out strong convective weather monitoring, early warning and forecasting work , The information obtained is released to users in a timely manner in the form of text, graphics, etc.
其中预报预警的模型所使用的参数和阀值如下：The parameters and thresholds used in the forecast and early warning model are as follows:
(1)暴雨天气在V-3Theta图上的结构特征主要体现(1) The structural characteristics of heavy rain weather on the V-3Theta map are mainly reflected
强对流前后，对流层下层(700～500hPa)，θse、θ*与温度T呈钝角，位温随高度降低，存在不稳定层结。并随强对流的发展，不稳定层结厚度向上层发展。Before and after strong convection, in the lower troposphere (700-500hPa), θse, θ* form an obtuse angle with temperature T, the potential temperature decreases with height, and there is unstable stratification. And with the development of strong convection, the thickness of unstable stratification develops upward.
暴雨天气除了需要对流的不稳定条件，同时要求θse值高：平流层250hPa，满足θse≥80℃，对流层400hPa，满足θse≥70℃。可见暴雨对高温高湿的条件要求高，有利于强将水。In addition to the unstable conditions of convection, heavy rain weather also requires high θse values: 250hPa in the stratosphere meets θse≥80°C, and 400hPa in the troposphere meets θse≥70°C. It can be seen that heavy rain has high requirements on high temperature and high humidity conditions, which is conducive to strong water.
暴雨发生前后，平流层300hPa以上，三条曲线近似垂直于温度T，超低温现象明显，对流活跃，且此时满足θse≥80℃。200hPa以上，三条曲线近似重合，有利于强对流发展。Before and after the rainstorm, the stratosphere above 300hPa, the three curves are approximately perpendicular to the temperature T, the phenomenon of ultra-low temperature is obvious, the convection is active, and at this time θse≥80℃ is satisfied. Above 200hPa, the three curves approximately coincide, which is conducive to the development of strong convection.
(2)冰雹天气在V-3Theta图上的结构特征主要体现(2) The structural characteristics of hail weather on the V-3Theta diagram are mainly reflected
冰雹发生的前后，θ的三条曲线在300hPa高度及以上基本重合，空气干燥。顺滚流。这是冰雹与其他强对流天气最大的区别。Before and after the occurrence of hail, the three curves of θ basically coincide at a height of 300hPa and above, and the air is dry. Down the tumble. This is the biggest difference between hail and other strong convective weather.
强烈的非均匀结构。θ线近乎垂直于T轴或与T轴成钝角，θse、θ*与T轴成较大角度的钝角，水汽的分布也呈现强烈的非均匀，θse和θ*围成的面积有明显的″细腰″或″大肚″的图像特征。冰雹发生前后会出现″大肚″图像，主要存在于600～500hPa。此处的|θ*-θse|的差值达到最大，为5K左右。且冰雹过程，700～300hPa之间，θse值的大小在45℃～50℃左右。strongly heterogeneous structure. The θ line is almost perpendicular to the T-axis or forms an obtuse angle with the T-axis. θse and θ* form a relatively large obtuse angle with the T-axis. The distribution of water vapor is also strongly non-uniform. The image characteristics of "thin waist" or "big belly". Before and after the occurrence of hail, there will be a "big belly" image, which mainly exists at 600-500hPa. Here the difference of |θ*-θse | reaches the maximum, which is about 5K. And in the process of hail, between 700hPa and 300hPa, the value of θse is around 45℃～50℃.
(3)暴雪天气在V-3Theta图上的结构特征主要体现(3) The structural characteristics of the snowstorm on the V-3Theta map are mainly reflected
暴雪前后对流层中，400～300hPa高度上，由于冰晶的不断增长，水汽含量的不断减少，θse曲线随时间由靠近θ*曲线，转向靠近θ曲线。700～400hPa之间，θse与θ*逐渐靠近，但走向不完全一致，并且在某一高度达到近似重合。可见，暴雪在对流层要求的水汽量比暴雨要少，饱和程度要低。In the troposphere before and after the snowstorm, at the height of 400-300hPa, due to the continuous growth of ice crystals and the continuous decrease of water vapor content, the θse curve turns from close to the θ* curve to close to the θ curve with time. Between 700hPa and 400hPa,θse and θ* are gradually approaching, but the directions are not completely consistent, and they reach approximate coincidence at a certain height. It can be seen that the amount of water vapor required by blizzard in the troposphere is less than that of heavy rain, and the degree of saturation is lower.
暴雪结束后，对流层和平流层底部的θse值迅速降低，且与其他类型强对流天气相比，降低变化大，MAX|Δθse|≈20℃。θse与θ两条曲线在整层近似重合，几乎已经没有水汽的存在。After the blizzard ended, the θse values in the troposphere and the bottom of the stratosphere decreased rapidly, and compared with other types of strong convective weather, the decrease changed greatly, MAX|Δθse |≈20 ℃. The two curves of θse and θ approximately overlap in the whole layer, almost no water vapor exists.

The entire system is divided into the following four levels: application presentation layer, business system layer, data layer, and system platform. The application presentation layer is the direct interaction between the system and the user, and currently supports two methods: browser-based and mobile APP applications; the application service layer is the functions that can be realized by the entire system, including meteorological monitoring, meteorological disaster factor management, disaster forecasting, Five subsystems of early warning and background management; the data layer is the data core of the system, mainly including basic geographic information database and business database, of which the business database is divided into: meteorological monitoring database, risk assessment database; system platform as the system development environment and operating environment , mainly including WebServer platform, WebGIS platform, JavaEE framework, operating system and database management system, as well as supporting hardware environment.
数据层：该层以数据库方式存储大量的数据信息和数据逻辑，并完成与数据有关的安全、完整性控制、数据的一致性和并发操作。Data layer: This layer stores a large amount of data information and data logic in the form of a database, and completes data-related security, integrity control, data consistency, and concurrent operations.
业务逻辑层：该层是系统的核心部分，它根据用户从表现层发送的请求，按照业务逻辑与数据层打交道，完成数据的存取和传输。Business logic layer: This layer is the core part of the system.

表现层：该层主要实现各类业务对象在客户端的显示，以及提供用户对各类业务和事务进行处理的业务规则。Presentation layer: This layer mainly implements the display of various business objects on the client side, and provides business rules for users to process various businesses and transactions.
本发明系统的数据库包括字典表、行政区划表、气象信息表、研判记录、预警分析表以及映射表等。The database of the system of the present invention includes a dictionary table, an administrative division table, a meteorological information table, a research and judgment record, an early warning analysis table, and a mapping table.
1、数据对象命名规则1. Data object naming rules
在本数据库结构设计中，表名以T开头和Q_开头，视图以V开头，以示区分。其中T_开头的表是预警分析的数据库表，Q_开头的表是气象监测数据的表。In this database structure design, table names start with T and Q_, and views start with V to distinguish them. The table starting with T_ is the database table for early warning analysis, and the table starting with Q_ is the table of meteorological monitoring data.
数据库表结构中“是否有效”字段，1表示是，0表示否。In the "valid" field in the database table structure, 1 means yes, and 0 means no.
2、数据库建库规则2. Database building rules
2.1、数据库SID2.1. Database SID
数据库SID是唯一标志数据库的符号，命名长度不能超过5个字符。对于本项目的数据库SID命名为LAND。The database SID is a symbol that uniquely identifies the database, and the length of the name cannot exceed 5 characters. The database SID for this project is named LAND.
2.2、数据库SGA配置2.2, database SGA configuration
数据库SGA可以采用手工配置或按物理内存比例配置，在数据库初始设计阶段采用按比例配置方式，在实际应用中按系统调优方式修改SGA。The database SGA can be manually configured or configured according to the physical memory ratio.

5、数据库表空间设计5. Database table space design
当表空间大小小于操作系统对最大文件限制时，表空间由一个文件组成。如果表空间大小大于操作系统对最大文件限制时，该表空间由多个数据文件组成。一般windows32位系统的文件最大2G，64位的UNIX系统系统文件最大128G，但也要注意文件格式设定的文件大小，建议最大为2G。表空间采用local管理方式。对于系统所使用的表空间，为了便于日常监控，因此不考虑采用自动扩展的方式。When the size of the table space is smaller than the maximum file limit of the operating system, the table space consists of one file. If the size of the table space is larger than the maximum file limit of the operating system, the table space consists of multiple data files. Generally, the maximum file size of windows 32-bit system is 2G, and the maximum file size of 64-bit UNIX system system is 128G. However, we should also pay attention to the file size set by the file format. It is recommended that the maximum file size be 2G. The table space is managed locally. For the table space used by the system, in order to facilitate daily monitoring, automatic expansion is not considered.
