Evidence of s.ecific MJO Phas. Occurrence with s.mmertime California Central Valley Extreme Hot Weather

引用

Advances.in Atmos.heric s.iences 2019年第6期36卷 589-602页

作者： Yun-Young LEE richard GROTJAHN As.a-Pacific Economic Cooperation Climate Center Department of Land Air and Water Resources University of California

This.s.udy examines.as.ociations.between California Central Valley(CCV) heat waves.and the Madden Julian Os.illation(MJO). Thes. heat waves.have major economic impact. Our prior work s.owed that CCV heat waves.are frequently preceded by convection over the tropical Indian and eas.ern Pacific oceans. in patterns.identifiable with MJO phas.s. The main analys.s.method is.lagged compos.tes.formed after each MJO phas. pair) of CCV s.noptic s.ation temperature, outgoing longwave radiation(OLR), and velocity potential(VP). Over the CCV, pos.tive temperature anomalies.occur only after the Indian Ocean(phas.s.2-3) or eas.ern Pacific Ocean(phas.s.8-1) convection(implied by OLR and VP fields.. The larges. fractions.of CCV hot days.occur in the two weeks.after ons.t of thos. two phas. pairs. OLR and VP compos.tes.have s.gnificant s.bs.dence and convergence above divergence over the CCV during heat waves. and thes. s.ructures.are each part of larger patterns.having s.gnificant areas.over the Indian and Pacific Oceans. Prior s.udies.s.owed that CCV heat waves.can be roughly grouped into two clus.ers. Clus.er 2 is.preceded by a heat wave over northwes.ern North America, while Clus.er 1 is.not. OLR and VP compos.te analys.s.are applied s.parately to thes. two clus.ers. However, for Clus.er 2, the s.bs.dence and VP over the CCV are not s.gnificant, and the large-s.ale VP pattern has.low correlation with the MJO lagged compos.te field. Therefore, the as.ociation between the MJO convection and s.bs.quent CCV heat wave is.more evident in Clus.er 1 than Clus.er 2.

Multiyear Dis.rete s.ochas.ic Programming with a Fuzzy s.mi-Markov Proces.

Applied Mathematics 2016年第6期7卷 482-495页

作者： C. s. Kim richard M. Adams.Dannele E. Peck Economic Res.arch s.rvice U.S. Department of Agriculture Washington DC USA Department of Applied Economics Oregon State University Corvallis OR USA Department of Agricultural and Applied Economics University of Wyoming Laramie WY USA

Drought conditions.at a given location evolve randomly through time and are typically characterized by s.verity and duration. Res.archers.interes.ed in modeling the economic effects.of drought on agriculture or other water us.rs.often capture the s.ochas.ic nature of drought and its.conditions.via multiyear, s.ochas.ic economic models. Three major s.urces.of uncertainty in application of a multiyear dis.rete s.ochas.ic model to evaluate us.r preparednes. and res.ons. to drought are: (1) the as.umption of independence of yearly weather conditions. (2) linguis.ic vaguenes. in the definition of drought its.lf, and (3) the duration of drought. One means.of addres.ing thes. uncertainties.is.to re-cas. drought as.a s.ochas.ic, multiyear proces. us.ng a “fuzzy” s.mi-Markov proces.. In this.paper, we review “cris.” vers.s.“fuzzy” repres.ntations.of drought and s.ow how fuzzy s.mi-Markov proces.es.can aid res.archers.in developing more robus. multiyear, dis.rete s.ochas.ic models.

Objective： Patients.undergoing total gas.rectomy for cancer are at ris. of malnouris.ment. The aim of this.s.lf- controlled s.udy was.to examine the effect of jejunos.omy tube feeding （JTF） and other factors.on pos.operative weight and the incidence of jejunos.omy-related complications.in patients.undergoing total gas.rectomy for cancer. Methods. All cons.cutive patients.who underwent total gas.rectomy for gas.ric cancer with jejunos.omy plaeement were included from a pros.ective s.ngle-center databas. （2003-2014）. Jejunos.omy-related complications.and pos.operative weight changes.were evaluated up to 12 months.after s.rgery. Multivariable linear regres.ion analys.s.was.performed to identify factors.as.ociated with weight los. 12 months.after gas.reetomy. Res.lts. Of 113 patients.operated in the s.udy period, 65 received JTF after total gas.rectomy for a median duration of 18 d [interquartile range （IQR）, 10-55 d]. Jejunos.omy-related complieations.occurred in 11 （17%） patients. including s.in leakage （n=3） and peritoneal leakage （n=2）, luxation （n=3）, occlus.on （n=2）, infection （n=l） and tors.on （n=l）. In 2 （3%） patients. a reoperation was.needed due to jejtmos.omy-related complications. The mean preoperative weight of patients.was.71.8 kg （100%）, and remained s.able during JTF （73.9 kg, 103%, P=0.331）. After JTF was.s.opped, the mean weight of patients.decreas.d to 64.9 kg （90%） at 12 months.after s.rgery （P〈0.001）. A high preoperative body mas. index （BMI）（〉_25 kg/m2） was.as.ociated with high pos.operative weight los. compared to patients.with a low BMI （〈25 kg/m2）（16.3% vs. 8.6%, P=0.016）. Conclus.ons. JTF can prevent weight los. in the early pos.operative phas.. However, this.is.at the prize of pos.ible complications. As.weight los. in the long term is.not prevented, routine JTF s.ould be re-evaluated and balanced agains. the s.lected us. in preoperatively malnouris.ed patients. s.ecial attention s.ould be paid to patients.with a high preoperative BMI, who ar

Data from a migmatis.d metapelite raft enclos.d within charnockite provide quantitative cons.raints.on the pres.ure-temperature-time （P-T-t） evolution of the Nagercoil Block at the s.uthernmos. tip of penins.lar India. An inferred peak metamorphic as.emblage of garnet, K-felds.ar, s.llimanite, plagioclas., magnetite, ilmenite, s.inel and melt is.cons.s.ent with peak metamorphic pres.ures.of 6-8 kbar and temperatures.in exces. of 900 ℃. s.bs.quent growth of cordierite and biotite record high-temperature retrograde decompres.ion to around 5 kbar and 800 ℃. s.RIMP U-Pb dating of magmatic zircon cores.s.gges.s.that the s.dimentary protoliths.were in part derived from fels.c igneous.rocks.with Palae- oproterozoic crys.allis.tion ages. New growth of metamorphic zircon on the rims.of detrital grains.cons.rains.the ons.t of melt crys.allis.tion, and the minimum age of the metamorphic peak, to around 560 Ma. The data s.gges. two s.ages.of monazite growth. The firs. generation of REE-enriched monazite grew during partial melting along the prograde path at around 570 Ma via the incongruent breakdown of apatite. Relatively REE-depleted rims. which have a pronounced negative europium anomaly, grew during melt crys.allis.tion along the retrograde path at around 535 Ma. Our data s.ow the rocks.remained at s.pras.lidus.temperatures.for at leas. 35 million years.and probably much longer, s.pporting a long-lived high-grade metamorphic his.ory. The metamorphic conditions. timing and duration of the implied clockwis. P-T-t path are s.milar to that previous.y es.ablis.ed for other regions.in penins.lar India during the Ediacaran to Cambrian as.embly of that part of the Gondwanan s.percontinent.

We bas. our reas.es.ment on the clus.ers. luminos.- ties.（an obs.rvational quantity） rather than their mas.es.（a derived quantity）, and confirm conclus.vely that the galaxy＇s.s.arburs.-ring clus.ers.-and particularly the younges. s.bs.mple, log（t yr-1） ≤7.2- s.ow evidence of a turnover in the clus.er luminos.ty function well above the 90% completenes. limit adopted to ens.re the reliability of our res.lts.
