      WTG cloud modeling with spectral decomposition of heating

      Michael J. Herman and David J. Raymond

      Accepted manuscript online: 21 OCT 2014 08:31AM EST | DOI: 10.1002/2014MS000359

      Key Points

      • A spectral form of the weak temperature gradient approximation is introduced
      • The spectral formulation is more accurate than the conventional scheme
      • WTG experiments should be more robust when using this scheme

      Accepted manuscript online: 20 OCT 2014 10:06PM EST | DOI: 10.1002/2014MS000331

      Key Points

      • Steady state soil organic carbon (SOC) can be estimated without long spin-up
      • Satellite leaf area index is used to calculate carbon source in the model
      • Model captured global variability of SOC across plant functional types

      Impact of precipitation-induced sensible heat on the simulation of land-surface air temperature

      Nan Wei, Yongjiu Dai, Minghua Zhang, Liming Zhou, Duoying Ji, Siguang Zhu and Lili Wang

      Accepted manuscript online: 20 OCT 2014 03:47AM EST | DOI: 10.1002/2014MS000322

      Key Points

      • HPR is calculated on a global long-term scale with a large amount in the ITCZ
      • HPR induces appreciable regional impact on TLSA simulation in northern winter
      • HPR helps to reduce TLSA simulation biases by up to 1 K at continental scales

      Accepted manuscript online: 16 OCT 2014 09:34PM EST | DOI: 10.1002/2014MS000332

      Key Points

      • First time-varying probabilistic ash cloud forecast maps
      • High-fidelity probability mapping / moment optimization and high-resolution winds
      • Testing of outputs with standard metrics and against multimodel and SKEB

      Evaluation of the impact of moist convection on the development of asymmetric inner core instabilities in simulated tropical cyclones

      Jason Naylor and David A. Schecter

      Accepted manuscript online: 13 OCT 2014 01:51AM EST | DOI: 10.1002/2014MS000366

      Key Points

      • Moist convection has little impact on initial asymmetric wave growth
      • Main source term of asymmetric KE involves radial shear of primary circulation
      • Moist convection reduces intensity loss otherwise caused by instabilities

      The effect of horizontal resolution on simulation quality in the Community Atmospheric Model, CAM5.1

      Michael F. Wehner, Kevin A. Reed, Fuyu Li, Prabhat, Julio Bacmeister, Cheng-Ta Chen, Christopher Paciorek, Peter J. Gleckler, Kenneth R. Sperber, William D. Collins, Andrew Gettelman and Christiane Jablonowski

      Accepted manuscript online: 13 OCT 2014 12:13AM EST | DOI: 10.1002/2013MS000276

      Key Points

      • The effects of increasing resolution in an atmospheric model are presented
      • Global models at 25 km can realistically simulate tropical cyclone statistics
      • Increased resolution alone does not improve model defects

      Sensitivity of the water cycle over the Indian Ocean and Maritime Continent to parameterized physics in a regional model

      Marcela Ulate, Jimy Dudhia and Chidong Zhang

      Accepted manuscript online: 8 OCT 2014 04:28AM EST | DOI: 10.1002/2014MS000313

      Key Points

      • The water cycle can be better simulated only by improving model physics
      • Biases produced by a PBL scheme can penetrate into the middle troposphere
      • Biases produced by cumulus schemes can penetrate into the boundary layer

      Remote effect of the model cold bias in the tropical North Atlantic on the warm bias in the tropical southeastern Pacific

      Liping Zhang, Chunzai Wang, Zhenya Song and Sang-Ki Lee

      Accepted manuscript online: 8 OCT 2014 04:21AM EST | DOI: 10.1002/2014MS000338

      Key Points

      • A close link between tropical North Atlantic and southeastern Pacific SST bias
      • The TNA cold bias does contribute partly to the warm SST bias in the SEP
      • This link is due to the TNA-SEP Hadley cell change

      Investigating ice nucleation in cirrus clouds with an aerosol-enabled multiscale modeling framework

      Chengzhu Zhang, Minghuai Wang, Hugh Morrison, Richard C. J. Somerville, Kai Zhang, Xiaohong Liu and Jui-Lin F. Li

      Accepted manuscript online: 10 SEP 2014 01:53AM EST | DOI: 10.1002/2014MS000343

      Key Points

      • Aerosol-depended ice nucleation is enabled in PNNL MMF
      • New MMF captures persistent ice supersaturation and low ice number in cirrus
      • MMF is powerful in emulating cloud processes evolving over short time scale
