Abstract

The invention provides an internal pulling bay sea ice thickness simulation method and system. The internal pulling bay sea ice thickness simulation method comprises the following steps that the sea ice thickness of the previous moment, the average temperature value from the previous moment to the current moment and the number of days from the previous moment to the current moment of an internal pulling bay are obtained; according to the obtained data, obtaining an inner pulling bay sea ice thickness simulation result at the current moment; according to the method, correlation analysis and model construction are carried out by using long-time sequence sea ice thickness data and automatic weather station air temperature observation data, and only time sequence air temperature data are needed as parameters, so that the requirements of other algorithms on complex parameters are simplified, and the sea ice growth process can be accurately simulated.

Description

technical field [0001] The invention relates to the technical field of sea ice thickness simulation, in particular to a method and system for simulating sea ice thickness in Nera Bay. Background technique [0002] The statements in this section merely provide background art related to the present invention and do not necessarily constitute prior art. [0003] The existing model algorithm needs various parameters such as temperature, salinity, snow thickness, etc., and its universality is poor. After testing, it is not suitable for the calculation of sea ice thickness in the Nera Bay, and the error is large. [0004] Neila Bay is adjacent to the Zhongshan Scientific Research Station in Antarctica. It is an important place and passage for scientific expedition members to conduct scientific investigations, as well as annual ice unloading and outstation exchanges. Therefore, the calculation of sea ice thickness in this area is related to the scientific research of Zhongshan Stat...
