Climate and Forecast Mode Simulations for Antarctica:implications for Temperature and Wind

引用

Advances in Atmospheric Sciences 2010年第6期27卷 1453-1472页

Climate and forecast mode simulations with the regional climate model HiRlam-eCHAM（HiRHAM） are evaluated over a pan-Antarctic domain. The ability of the model to simulate temperature and wind profiles in the troposphere is quantified by comparing its results with radiosonde data acquired from the Davis station for January and July 2007. Compared to the climate mode, the forecast mode was found to deliver improved results for temperature and wind simulations at the near surface and in the lower troposphere. The main remaining model bias found was the under-representation of low-level wind jets. Based on ensemble simulations, it is shown that a distinct internal variability is inherent in the climate mode simulations, and associated areas of reduced predictability over Antarctica are identified.

effects of submergence in water on seed germination and vigor of the Copaifera lucens(Fabaceae) seedlings

Journal of Forestry Research 2014年第4期25卷 903-908页

We analyzed the tolerance of Copaifera lucens seeds to sub- mersion in water to assess the use of this species for direct seeding in riparian forest restoration programs. Seeds were submerged in water for 2, 4, 8, 16 and 32 days or not submerged （control = 0 days of submer- gence）. For the control and at the end of each period of submersion, germination and seedling vigor tests were carried out. For germination tests, seeds were sown in plastic pots containing sand and kept in labora- tory conditions. The percentage of seed germination, the germination rate and the average germination time were analyzed. For seedlings, total biomass, leaf area, leaf mass per area and leaf area ratio were analyzed. Submersion time drastically affected the dissolved oxygen content and seed germination. Between 4 and 8 days of submersion there was a de- crease from 83.8% to 15.6% in the germination percentage. No seed germination occurred after 16 days of submersion. Although there was a significant decrease in the percentage of seed germination between 4 and 8 days of submersion, seedling vigor was not affected. Seeds of this species were partially tolerant to submersion in water, suggesting that C. lucens is a promising species for direct seeding in riparian forest restora- tion projects.

evaluation of climate and forecast mode simulations of the regional climate model HiRHAM over a pan-Antarctic domain is presented. The improved skill of the permanent re- initialization during the forecast mode simulations is quantified for the temperature- and wind fields, exemplarily for the Davis station during the two extreme months of the annual cycle of 2007. in July, the forecast mode improved the temperature simulation largely at near surface/low troposphere. Differently in January, the frequent re-initialization could not improve much the temperature bias at the near surface/lower troposphere. That is an indication that the remaining bias is mainly due to inadequate model physical parameterizations （and not due to deviations from the large-scale forcing）. The improved skill in the forecast mode is also quantified for the wind simulation. Despite of the specific biases, the simulations accurately capture the synoptic variability in the observed temperature and wind with reasonable accuracy. However, the model underestimates the wind speed for periods of higher wind speeds, so that strong low-level wind jets are not well simulated. The model tends to generate the wind jet less often and at lower heights, and the core wind speed is lower compared to what is observed.

＜正＞ By examining viscoelastic functions of poly （ethylene terephthalate）/ poly （ethylene naphthalate） blends, we found that the departure of classic viscoelasticity happened in low frequency. The relationships between dynamic storage moduli G’（or dynamic loss moduli G"） vs. frequency igG’-lgωαT （or lgG"-lgωαT） depart from classic viscoelastic model. Time-temperature superposition （iTS） theory was inducted in studying the phase-separation phenomenon of PeT/PeN blends system. it is interesting that the breakdown of TTS depends on components. The lgG’-lgωαT curve is more sensitive than lgG"-lgωαT curve. Results indicate: PeT/PeN blends system is a kind of micro separate phase material. The primary reason of why the barrier properties of PeT/PeN blends are better than that of PeT is the lamellar structure formed after bi-oriented. But block copolymer produce by the transesterification reaction during PeT and PeN blend process change the separation of PeT and PeN illegibility so DSC can not examine the separation of PeT/PeN blends.
