Xiamen weather forecast accuracy 15 days

The accuracy of Xiamen weather forecast 15 days has no fixed value.

The weather forecast for the next 15 days is not very accurate. It is based on the analysis of satellite cloud images and weather maps, combined with the comprehensive study of meteorological data, terrain and seasonal characteristics, and mass experience. Due to the confusion of atmospheric process and the incomplete understanding of atmospheric process, there will always be some errors in weather forecast.

Any forecasting model can't completely and truly simulate the evolution of the atmosphere, it can only be approximate, so there must be errors. Moreover, the error will accumulate, and the longer the prediction time, the greater the error. Model weather forecast is to design a huge program to calculate weather forecast, and input the currently known weather phenomena, so that it can calculate the future atmospheric motion state and weather conditions.

Precautions:

The forecast of 1 and 8- 15 days is objectively revised, but it has not been subjectively revised by forecasters, so there is some uncertainty. It can be seen that it is very important for meteorologists to make subjective corrections according to their majors and experiences.

The weather forecast is revised within 2.7 days. Based on the data of current local weather conditions obtained by artificial observation on the ground, high-altitude detection, radar satellite and ocean buoy station, the initial field of the model is closer to the actual situation, and the simulated atmospheric change characteristics are more reliable. But for the longer-term prediction, most of the data are completely generated by model calculation, and the credibility is gradually decreasing.
