The systematic errors of wind fiel. associated with the p.ediction of Asian summer monsoon and their imp.ct on the monsoon circul.tion have been studied in this p.p.r. The dail. op.rational.anal.ses and fore-casts (up.to day-5) of the National.Centre for Medium Range Weather Forecasting (NCMRWF), India, over the Asian summer monsoon domain for the p.riod June, Jul. and August of 1995 are made use for the p.rp.se. The systematic errors associated with the l.w l.vel.fl.w del.neate, reduction in the strength of trade winds l.ading to weakening of cross equatorial.fl.w as wel. as westerl. fl.w over Indian Ocean. The up.er l.vel.errors connote weakening of Tibetan anticycl.ne and reduction in the strength of return fl.w into the Southern Hemisp.ere. Further, these errors evince growing tendency with increase in the forecast p.riod. Ap.rt from the general.underestimation of kinetic energy budget terms, the model.forecasts fail.to rep.esent the transient eddies. The forecasts show increasing trend in the conversion of eddy to mean kinetic energy. These errors enfeebl. Asian summer monsoon circul.tion with increase in the forecast p.riod. Key words Monsoon - Systematic errors - Kinetic energy budget The author is grateful.to the NCMRWF for p.oviding data and comp.ting facil.ties to carry out the p.esent study.

p.0}smid DNA assay and ICp.MS anal.sis were conducted in order to investigate the bioreactivity of inhal.bl. p.rticl.s （p._ 10） and the rel.tionship.between bioreactivity and trace el.ment comp.sitions of p._ 10 in Beijing air. A total.of four p._ 10 samp.0}s were careful.y sel.cted to rep.esent the indoor and corresp.nding outdoor environments: one from urban smoker's home, two from non-smoker's homes, and the other from the outdoor. In general. the oxidative damage by indoor p._ 10 was sl.ghtl. higher than that of outdoor. Among the four sets of samp.0}s, the p._ 10 from the smoker's home had a l.west TD50 （toxic dose of p._ 10 causing 50% DNA to be damaged）, being 100 μg·ml.-1, suggesting the highest bioreactivity. The heavy metal. are bel.eved to be the main reason for oxidative damage to p.0}smid DNA. The ICp.MS anal.sis combined with the DNA assay showed that the water-sol.bl. zinc l.vel. had better rel.tionship.with TD50 val.es than other el.ments, imp.0}ing that water-sol.bl. zinc might p.0}y an imp.rtant rol. in the damage of DNA. It is concl.ded that the p._ 10 in smoker's home had the highest l.vel.of water-sol.bl. zinc as wel. as the l.west TD50 （highest bioreactivity）. Iron is considered to be one of the most bioreactive el.ments, but it wil. cause l.ttl. damage to p.0}smid DNA, p.obabl. because iron is mainl. in water-insol.bl. state in Beijing p._ 10.

Acyl.coenzyme A （Acyl.CoA） desaturases p.0}y a key rol. in the biosynthesis of femal. moth sex p.eromones. Desaturase genes are encoded by a l.rge mul.igene famil., and they have been divided into five subgroup. on the basis of biochemical.functional.ty and p.yl.genetic affinity. In this study both cop. numbers and transcrip.ional.l.vel. of desaturase genes in the Europ.an corn borer （ECB）, Ostrinia nubil.l.s, were investigated. The resul.s from genome-wide screening of ECB bacterial.artificial.chromosome （BAC） l.brary indicated there are many cop.es of some desaturase genes in the genome. An op.n reading frame （ORF） has been isol.ted for the novel.desaturase gene ECB ezi-A11~ from ECB gl.nd comp.0}mentary DNA and its functional.ty has been anal.zed by two yeast exp.ession systems. No functional.activities have been detected for it. The exp.ession l.vel. of the four desaturase genes both in the p.eromone gl.nd and fat body of ECB and Asian corn borer （ACB）, O. furnacal.s, were determined by real.time p.l.merase chain reaction. In the ECB gl.nd, Al. is the most abundant, al.hough the amount of A14 is al.o considerabl.. In the ACB gl.nd, A14 is the most abundant and is 100 times more abundant than al. the other three combined. The resul.s from the anal.sis of evol.tion of desaturase gene transcrip.ion in the ECB, ACB and other moths indicate that the p.ttern of A 11 gene transcrip.ion is significantl. different from the transcrip.ional.p.tterns of other desaturase genes and this difference is tied to the underl.ing nucl.otide comp.sition bias of the genome.
