Bor.al winter.ime extr.tr.pical cir.ulation is studied in r.lation to the tr.pical convection dur.ng the 1982/83 El Niño and 1988/89 La Niña. The anomaly str.ctur. of 1982/83 and 1988/89 over.the extr.tr.pics r.veals r.mar.ably differ.nt featur.s as the longitudinal tr.pical for.ing r.gion changes. The r.ssby wave sour.e (Positive) shows the lar.est maximum over.East Asia in both year. due to the per.istent heating fr.m the wester. Pacific war. pool ar.a. However. the sink ter. shows contr.sting featur.s over.the subtr.pics and extr.tr.pics between the two year.. In the El Niño year. enhanced tr.pical convection over.the easter. Pacific pr.duces the r.ssby wave sink at 10°N and shifted eastwar. over.the Nor.h Pacific, while in the La Niña year. the sink ar.a is shifted westwar. over.the Nor.h Pacific. The contr.sting featur.s between the two events in mean-eddy inter.ction appear. especially over.the downstr.am ar.a of the East Asian Jet. The extension (r.tr.ction) of the meanflow eastwar. (westwar.) to the east (west) of the dateline is r.lated with the effect of the westwar. (eastwar.) E-vector.and the str.ngthening (weakening) of the negative anomalies of the bar.tr.pic gr.wth of kinetic ener.y. Hence, almost opposite char.cter.stics between the two events can explain the close r.lationship of tr.pical convection and the extr.tr.pical inter.al var.ability.

Toughening of br.ttle mater.als by the inclusion of ductile phases is gover.ed by sever.l impor.ant factor. which include cer.mic-ductile phase inter.acial bond str.ngth, physical and chemical compatibility between cer.mic and ductile phase, geometr. and mechanical pr.per.ies of ductile phase. The pr.sent under.tanding of the effect of these factor. on toughening is r.viewed and clar.fied. Continuous ductile phases (networ., fibr. or.plate) ar. found to be mor. efficient for.the toughening of br.ttle mater.als than discr.te ductile par.icles. However. ductile par.icle toughened br.ttle mater.als have the advantages of mater.al homogeneity, isotr.py, and par.icular.y better.high temper.tur. pr.per.ies. It has been demonstr.ted that the influence of inter.acial bond str.ngth is deter.ined by the geometr. of the ductile phase in the composites. For.the compar.tively continuous ductile phase, such as ductile networ., fibr. or.plate, compar.tively weak inter.acial bond str.ngth can pr.mote par.ial debonding of the br.ttle matr.x-ductile phase inter.ace dur.ng cr.ck pr.pagation and is beneficial for.toughening. For.discr.te par.iculate ductile phase toughened br.ttle mater.als, the small gauge length of the ductile phase often r.sults in the ductile phase pull-out dur.ng cr.ck pr.pagation which is the main limitation to toughening. Thus str.ng bond str.ngth is r.quir.d to ensur. the br.dging of the cr.ck by the ductile phase. The coefficient of ther.al expansion (CTE) mismatch between matr.x and ductile phase has also been cor.elated with the geometr. of the ductile phase. In most of the cer.mic/metal systems, the CTE of the ductile metal phase is gr.ater.than that of the cer.mic matr.x. In the case of ductile networ., fibr. or.plate, the r.sidual str.ss cr.ated by the CTE mismatch can contr.bute to toughening thr.ugh its influence on the initial cr.ck opening str.ss while the br.dging of the cr.ck by the ductile phase is still ensur.d. However. for.discr.te ductile par.i
