A recent version of the Polar Weather Research and Forecasting model(Polar WRF)has been upgraded to the version 4.X era with an improved NoahMP Land Surface Model(LSM).To assess the model performance over the Antarctic and Southern Ocean,downscaling simulations with different LSM(NoahMP,Noah),WRF versions(Polar WRF 4.1.1 and earlier version 4.0.3,WRF 4.1.1),and driving data(ERA-Interim,ERA5)are examined with two simulation modes:the short-term that consists of a series of 48 h segments initialized daily at 0000 UTC with the first 24 h selected for model spin-up,whereas the long-term component used to evaluate long-term prediction consists of a series of 38-41 day segments initialized using the first 10 days for spin-up of the hydrological cycle and planetary boundary layer *** using short-term mode driven by ERA-Interim with NoahMP and Noah are selected for benchmark *** results show that Polar WRF 4.1.1 has good skills over the Antarctic and Southern Ocean and better performance than earlier *** reduced downward shortwave radiation bias released with WRF 4.1.1 performed well with *** NoahMP and Noah led to very similar conclusions,NoahMP is slightly better than Noah,particularly for the 2 m temperature and surface radiation because the minimum albedo is set at 0.8 over the ice ***,a suitable nudging setting plays an important role in long-term forecasts,such as reducing the surface temperature diurnal cycle near the *** characteristics investigated in this study provide a benchmark to improve the model and guidance for further application of Polar WRF in the Antarctic.

极区给气象带来了一些独特的挑战,包括遥远和恶劣的环境。我们总结了两个半球极地气象的演化,这一过程始于早期探险阶段进行的观测,一直到最近几十年以来,极地气象成为全球核心挑战,如臭氧洞、天气预报和气候变化。虽然从1800年代和1900年代初的探险中得到一些数据,以及在亚北极区域仅有少量几个站,过去100年在观测网建立和对极地区域气象相关认识方面取得了极大的进步。例如,20世纪早期,人们一直认为北冰洋被持续的高压环流、冰川反气旋占据。随着观测的增加,到1950年代已经明了,尽管反气旋是北极循环的一个常见特征,气旋也频繁出现在北极的任何地方。技术通过改进仪器让极地气象受益,尤其是自动化的业务仪器。而且,卫星遥感和计算模式带来极地气象的革命。我们着重说明了四次国际极地年和最近几十年实施的一些高纬外场项目。我们还注意到巨大的挑战,包括认识北极在中纬度天气和气候变化中的作用、模拟变化中的北冰洋地表能量交换的能力、评估极区目前和未来极端事件的趋势和极地气候数年到年代变化内部变率的作用等。

Background:Acute improvement in range of motion(ROM)is a widely reported effect of stretching and foam rolling,which is commonly explained by changes in pain threshold and/or musculotendinous ***,these effects were also reported in response to various other active and passive interventions that induce responses such as enhanced muscle ***,we hypothesized that acute ROM enhancements could be induced by a wide variety of interventions other than stretching or foam rolling that promote an increase in muscle ***:After a systematic search in PubMed,Web of Science,and SPORTDiscus databases,38 studies comparing the effects of stretching and foam rolling with several other interventions on ROM and passive properties were *** studies had 1134 participants in total,and the data analysis resulted in 140 effect sizes(ESs).ES calculations were performed using robust variance estimation model with ***:Study quality of the included studies was classified as fair(PEDro score=4.58)with low to moderate certainty of *** showed no significant differences in ROM(ES=0.01,p=0.88),stiffness(ES=0.09,p=0.67),or passive peak torque(ES=-0.30,p=0.14)between stretching or foam rolling and the other identified *** plots revealed no publication ***:Based on current literature,our results challenge the established view on stretching and foam rolling as a recommended component of warm-up *** lack of significant difference between interventions suggests there is no need to emphasize stretching or foam rolling to induce acute ROM,passive peak torque increases,or stiffness reductions.
