Problems solved by technology

At present, the existing meteorological data storage methods mainly rely on centralized relational databases for storage. Although they have high security, the cost of data storage is high, and it is difficult to meet the requirements of large-scale processing of massive meteorological element data, and thus cannot Realize the provision of comprehensive meteorological information services for meteorology, industry, agriculture, hydrology and water conservancy, environmental protection, highways, airports and ports; therefore, how to efficiently store and quickly and comprehensively query massive meteorological element data in order to realize massive historical meteorological data. The value of has become the focus of current research

Abstract

The invention relates to a method and system for storing and querying massive meteorological element data, and the method comprises the steps: obtaining the massive meteorological element data collected by meteorological automatic stations in all regions hour by hour, and carrying out the statistical division of the data dimensions; extracting mass meteorological element data after data dimension statistical division, constructing a meteorological key value database comprising primary keys, sub-keys and key values, and meanwhile, taking meteorological automatic stations of all regions as primary indexes; wherein the primary indexes are in one-to-one correspondence with primary keys in the weather key value database; carrying out distributed cluster storage on the weather key value database; and carrying out cluster storage positioning on the names of the meteorological automatic stations of the to-be-queried region, and carrying out massive meteorological element data query. According to the method, massive meteorological element data can be efficiently stored and quickly and comprehensively queried, and the real value of massive historical meteorological data is realized; the method can be widely applied to the technical field of meteorological data processing.

Description

technical field [0001] The invention relates to the technical field of meteorological data processing, in particular to a method and system for storing and querying massive meteorological element data. Background technique [0002] Climate is an important part of the natural environment and the most important environmental condition for human activities; meteorological data is an important basis for analyzing meteorological conditions, and its application and research value is very high; through data mining and analysis of massive meteorological element data, it is possible to It helps to carry out meteorological forecast and disaster warning closely related to people's production activities and daily life, can realize the value-added service functions such as risk assessment of meteorological disasters, and can provide convenience for people's clothing, food, housing, transportation and other industries. [0003] With the rapid development of meteorological informatization,...
