评估CMIP6年代际预测试验对季节平均SAT的预测技巧的结果表明:模式不能有效预测冬季和秋季SAT的年代际变率.IPSL-CM6A-LR和多模式集合平均对于春季SAT展现了预测技巧,其中对于变率的预测技巧好于振幅的结果.基于蒙古和我国华北地区的显著预测技巧,模式对于夏季SAT表现出最佳的预测水平.与外部强迫相比,模式对于SAT的预测技巧可能来自初始化.模式中的一个明显系统性误差值得注意,即模式中冬季SAT的变率可以持续到其他季节,而在观测中其他季节的SAT变化与冬季SAT相对独立.

Dark matter is an essential component of the universe, accounting for approximately 85% of all matter. However,what the nature of dark matter actually is remains a huge mystery. So far, all evidence for the existence of dark matter has come from gravitational interactions. Since gravitational interactions are universal, it is challenging to reveal the nature of dark matter through gravitational interactions. To unravel the mystery of dark matter, it is essential to directly detect dark matter.
