An analysis is made of the effects of topography on the summer atmospheric energetics of the Northern Hemisphere in a low-resolution global spectral model. The numerical model is a global, spectral, primitive equation model with five equally spaced sigma levels in the vertical and triangular truncation at wavenumber 10 in the horizontal. The model includes comparatively full physical *** term of the energy budget equations is calculated in four specific latitudinal belts (81.11°S-11.53°S; 11.53°S-11.53°N; 11.53°N-46.24°N; 46.24癗-***癗) from a five-year simulation with mountains and a one-year simulation without mountains, respectively. Differences between them are compared and statistically tested. The results show that synoptical scale waves transport available potential energy and kinetic energy to long waves and increase conversion from available potential energy of the zonal flow to eddy's and from the eddy kinetic energy to the zonal kinetic energy in region 3 (11.53°N-46.24°N

Model–proxy comparison for overshoot phenomenon of Atlantic thermohaline circulation at Bφlling–Allerφd

The overshoot phenomenon of the Atlantic thermohaline circulation(THC) is a transient climate response to meltwater forcing and could induce intense climate change by increasing the magnitudes of Atlantic THC changes at the end of meltwater discharges. This phenomenon was formally presented with the successfully simulated Bφlling–Allerφd(BA) event in the first transient simulation of the last deglaciation with fully coupled model NCAR-CCSM3(TraCE-21K). Currently, not all proxy records of Atlantic THC support the occurrence of the THC overshoot at BA. Commonly used THC proxy from Bermuda Rise(GGC5) does not exhibit THC overshoot at BA but other proxies such as TTR-451 at Eirik Drift do. How to interpret this regional discrepancy of proxy records is a key question for the validation of the Atlantic THC overshoot at BA. Here, we show that the vigor of deep circulation varies regionally during the Atlantic THC overshoot at BA in TraCE-21 K simulation, and this regional discrepancy in the simulation is consistent with that in the marine sediment records in North Atlantic. The consistent model–proxy evidence supports the occurrence of Atlantic THC overshoot at BA.

国际古气候模拟比较计划(PMIP)是古气候领域里的一项长期开展的大型国际研究计划。该计划的主旨是利用气候数值模式,通过开展一系列针对古气候变化的模拟试验理解全球气候变化的机理,确定气候系统内部的各种影响气候变化的关键反馈因子;通过比较不同气候模式对不同于现代气候(古气候)的模拟能力评价模式的优劣,进而促进气候模式的发展;同时也为全球变化背景下利用气候模式预估未来气候变化提供借鉴。PMIP自1991年酝酿开始至今经历了PMIP1(1991～2001年)、PMIP2(2002～2007年)两个阶段,并正在开展第三阶段(PMIP3)(2008～)的研究。本文简要回顾了近10年来PMIP研究进展及概述了未来PM1P将要开展研究的重点领域和方向,主要包括4个主题:1)基准(benchmark)时段(6kaB.P.和21 kaB.P.)模拟;2)间冰期和温暖期气候模拟;3)快速气候变化模拟;4)不确定性研究。

In order to investigate the impact of the smoothed orography and the spurious orographic ripples on simulations in the low-resolution spectral model, three different numerical tests, that is, the unsmoothed orography scheme, the smoothed orography scheme and non-ripples scheme are performed. In this paper, the model used by us is the same as Part I except for orographic *** results from simulations indicate that, as far as the climatic simulation is concerned, some aspects of the simulated stationary disturbances, zonal and meridional wind, temperature and precipitation in the low-resolution spectral model with properly smoothed mountains are significantly improved, especially in winter *** deep ripples in the model with the unsmoothed orography produce spurious high pressure regions at the surface with subsidence, and suppress rainfall, causing an unrealistic splitting of the precipitation area in northern winter and summer.

基于使用全耦合模式的末次冰消期(显著的全球增暖阶段)瞬变模拟结果,通过敏感性试验明确指出温盐环流(Thermohaline Circulation,THC)在百年尺度上大幅度影响中国气候,特别是在气候突变阶段.结果表明,该瞬变模拟中中国地区的气候演变符合古气候资料的纪录,如Bφlling-Allerφd(BA)增暖事件期间中国地区的年平均气温大幅度升高;在敏感性试验中,当人为限制THC在BA事件期间的变化幅度时,中国地区的升温幅度明显减小.结果同时表明,除温室气体、太阳辐射强度因素外,THC是另外一个在百年尺度上影响中国气候的重要因素.

The effects of orography on the global characteristics of momentum, heat and moisture transports in a low-resolution spectral model

引用

Acta Oceanologica Sinica 1988年第S1期 140-152页

作者： Bctte l. otto-bliesner,David D. Houghton Department of Meteorology University of Wisconsin Madison WI 53706 U.S.A. Department of Meteorology University of Wisconsin Madison WI 53706 U.S.A.

In order to verify simulation capability of a low-resolution spectral model, analysis is made of the vertical and meridional transports of heat, angular momentum and moisture including their seasonal and interannual variation and sensitivity to effects of topography. Transports in the model arc compared with observations, and results from the model with topography absent. The comparison shows that the low-resolution spectral model truncated at wave number 10 is able to simulate the main climatic characteristics for total momentum, heat and moisture transports. The effects of topography on the simulated transports in winter are consistent with Manabe and Terpstra (1974) who concluded that the effects of mountains increased the northward transports of various quantities by the standing eddies but decreased those by transient eddies in January. Our simulation further indicates that the effects of topography on transports not only change with season, but also the geographic extent of its significant effects
