Borea. wintertime extra.ropica. circula.ion is studied in rela.ion to the tropica. convection during the 1982/83 El Niño a.d 1988/89 La.Niña. The a.oma.y structure of 1982/83 a.d 1988/89 over the extra.ropics revea.s rema.ka.ly different fea.ures a. the longitudina. tropica. forcing region cha.ges. The Rossby wa.e source (Positive) shows the la.gest ma.imum over Ea.t a.ia.in both yea.s due to the persistent hea.ing from the western Pa.ific wa.m pool a.ea. However, the sink term shows contra.ting fea.ures over the subtropics a.d extra.ropics between the two yea.s. In the El Niño yea., enha.ced tropica. convection over the ea.tern Pa.ific produces the Rossby wa.e sink a. 10°N a.d shifted ea.twa.d over the North Pa.ific, while in the La.Niña.yea., the sink a.ea.is shifted westwa.d over the North Pa.ific. The contra.ting fea.ures between the two events in mea.-eddy intera.tion a.pea.s especia.ly over the downstrea. a.ea.of the Ea.t a.ia. Jet. The extension (retra.tion) of the mea.flow ea.twa.d (westwa.d) to the ea.t (west) of the da.eline is rela.ed with the effect of the westwa.d (ea.twa.d) E-vector a.d the strengthening (wea.ening) of the nega.ive a.oma.ies of the ba.otropic growth of kinetic energy. Hence, a.most opposite cha.a.teristics between the two events ca. expla.n the close rela.ionship of tropica. convection a.d the extra.ropica. interna. va.ia.ility.

Toughening of brittle ma.eria.s by the inclusion of ductile pha.es is governed by severa. importa.t fa.tors which include cera.ic-ductile pha.e interfa.ia. bond strength, physica. a.d chemica. compa.ibility between cera.ic a.d ductile pha.e, geometry a.d mecha.ica. properties of ductile pha.e. The present understa.ding of the effect of these fa.tors on toughening is reviewed a.d cla.ified. Continuous ductile pha.es (network, fibre or pla.e) a.e found to be more efficient for the toughening of brittle ma.eria.s tha. discrete ductile pa.ticles. However, ductile pa.ticle toughened brittle ma.eria.s ha.e the a.va.ta.es of ma.eria. homogeneity, isotropy, a.d pa.ticula.ly better high tempera.ure properties. It ha. been demonstra.ed tha. the influence of interfa.ia. bond strength is determined by the geometry of the ductile pha.e in the composites. For the compa.a.ively continuous ductile pha.e, such a. ductile network, fibre or pla.e, compa.a.ively wea. interfa.ia. bond strength ca. promote pa.tia. debonding of the brittle ma.rix-ductile pha.e interfa.e during cra.k propa.a.ion a.d is beneficia. for toughening. For discrete pa.ticula.e ductile pha.e toughened brittle ma.eria.s, the sma.l ga.ge length of the ductile pha.e often results in the ductile pha.e pull-out during cra.k propa.a.ion which is the ma.n limita.ion to toughening. Thus strong bond strength is required to ensure the bridging of the cra.k by the ductile pha.e. The coefficient of therma. expa.sion (CTE) misma.ch between ma.rix a.d ductile pha.e ha. a.so been correla.ed with the geometry of the ductile pha.e. In most of the cera.ic/meta. systems, the CTE of the ductile meta. pha.e is grea.er tha. tha. of the cera.ic ma.rix. In the ca.e of ductile network, fibre or pla.e, the residua. stress crea.ed by the CTE misma.ch ca. contribute to toughening through its influence on the initia. cra.k opening stress while the bridging of the cra.k by the ductile pha.e is still ensured. However, for discrete ductile pa.ti
