本文利用低频(15s)和高频(1s)全球定位系统(GPS)观测来研究2018年1月23号阿拉斯加科迪亚克岛MW7.9地震的同震位移。动态(高频GPS观测值)和准动态(震后2小时的低频GPS观测值)同震位移与静态GPS同震位移三者之间相互一致,符合走滑型地震的形变特征。静态与准动态位移的比较结果表明该地震发生后4天内的震后形变可忽略不计。我们通过静态位移场反演了五段断层模型中的断层滑移,并且推测最大的滑移发生在右旋南—南东走向(2.27m)和左旋北东走向(2.42m)的两个子断层上。反演得到地震矩M0为9.66×1020N·m(MW7.92)。在震后9个月时间内,12个附近GPS站点的水平形变均小于1cm,且最大震后形变值为7.4mm(Ac26站点)。衰减时间为6.4天的对数模型比衰减时间为75.0天的指数模型能更好地拟合震后观测数据。观测到的震后形变可以通过余滑和/或黏弹性松弛模型来解释。

The dominant annual cycle of sea surface temperature(SST)in the tropical Pacific exhibits an antisymmetric mode,which explains 83.4%total variance,and serves as a background of El Niño-Southern Oscillation(ENSO).However,there is no consensus yet on its anomalous impacts on the phase and amplitude of *** on data during 1982-2022,results show that anomalies of the antisymmetric mode can affect the evolution of ENSO on the interannual scale via Bjerknes feedback,in which the positive(negative)phase of the antisymmetric mode can strengthen El Niño(La Niña)in boreal winter via an earlier(delayed)seasonal cycle transition and larger(smaller)annual *** magnitude of the SST anomalies in the equatorial eastern Pacific can reach more than±0.3◦c,regulated by the changes in the antisymmetric mode based on random sensitivity *** reveal the spatial pattern of the annual cycle associated with the seasonal phase-locking of ENSO evolution and provide new insight into the impact of the annual cycle of background SST on ENSO,which possibly carries important implications for forecasting ENSO.

The underlying physics of QcD phase transition in the early Universe remains largely unknown due to its strong-coupling nature during the quark-gluon plasma/hadron gas transition, yet a holographic model has been proposed to quantitatively fit the lattice QcD data while with its duration of the first-order phase transition(FoPT) left undetermined. At specific baryon chemical potential, the first-order QcD phase transition agrees with the observational constraint of baryon asymmetry. It, therefore, provides a scenario for phase transition gravitational waves(GWs) within the standard model of particle physics. If these background GWs could contribute dominantly to the recently claimed common-spectrum red noise from pulsar timing array(PTA) observations, the duration of this FoPT can be well constrained, and the associated primordial black holes are still allowed by current observations.
