during the late expansion and recovery phases of a substorm from 07:35UT to 08:00UT on 24August 2005,Cluster satellites(C1 and C3)observed a series of earthward/dawnward bursty bulk flows(BBFs)and the repeated drops of energetic(-128keV)electron fluxes in the midtail plasma sheet(-18.1≤xGSM≤-16.9RE).By analyzing the BBF-associated changes in the charged particle’s loss cone,waves and energetic particles,we found that the loss of energetic electrons is mainly due to the pitch angle scatterings driven by the lower-band whistler waves in the BBF-impacted regions,whereas the influence of particle’s azimuth drifts(e.g.,the Ex×Bz drifts independent of charges)are quite weak *** the loss cone of the charged particles is narrow(half loss cone angleαc.15o)in the midtail plasma sheet,the BBFs can enlarge the particle’s loss cone through the compression of local magnetic *** isotropic electron pitch angle evolutions and concurrent flux drops certify that the plasma sheet energetic electrons can be rapid.y.scattered into the loss cone(2αc)in the process of whistler wave *** the energetic electrons can experience the northern and southern conjugated losses during the wave-particle resonant interactions,their flux drops are also considerable when the plasma sheet was swept by the BBFs with the whistler waves many *** observations indicate that the BBFs with intense whistler waves mainly lead to the loss of the plasma sheet energetic electrons through the wave-driven pitch angle scatterings.

创新驱动发展提高气象灾害防御能力——第30届中国气象学会年会

作者： P.S.zhao F.dong d.He x.J.zhao x.l.zhang W.z.zhang q.yao H.y.liu Institute of Urban Meteorology China Meteorological Administration Meteorological Science Institute of Hebei Meteorological Science Institute of Tianjin Chengde Meteorological Bureau

In order to study the temporal and spatial variations of PM 2.5 and its chemical compositions in the region of Beijing, Tianjin, and Hebei (BTH), PM 2.5 samples were collected at four urban sites in Beijing (BJ), Tianjin (TJ), Shijiazhuang (SJz), and Chengde (Cd), and also one site at Shangdianzi (Sdz) regional background station over four seasons from 2009 to 2010. The samples were weighted for mass concentrations and analyzed in the laboratory for chemical profiles of 19 elements (Al, As, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Ni, P, Pb, Sr, Ti, V, and zn), eight water-soluble inorganic ions (Na+ , NH4+ , K+ , Mg2+ , Ca2+ , Cl- , NO3- , and SO42- ), and carbon fractions (OC and EC). The concentrations of PM 2.5 and its major chemical species were season dependent and showed spatially similar characteristics in the plain area of BTH. The average annual concentrations of PM 2.5 were 71.8-191.2 μgm -3 at the five sites, with more than 90% of sampling d.y. exceeding 50 μg m -3 at BJ, TJ, and SJz. PM 2.5 pollution was most serious at SJz, and the annual concentrations of PM 2.5 , secondary inorganic ions, OC, EC, and most crustal elements were all highest. due to stronger photochemical oxidation, the sum of concentrations of secondary inorganic ions (NH4+ , NO3- , and SO42- ) was highest in the summer at Sdz, BJ, TJ, and Cd. Analysis of electric charges of water-soluble inorganic ions indicated the existence of nitric acid or hydrochloric acid in PM 2.5 . For all five sites, the concentrations of OC, EC and also secondary organic carbon (SOC) in the spring and summer were lower than those in the autumn and winter. SOC had more percentages of increase than primary organic carbon (POC) during the winter. The sums of crustal elements (Al, Ca, Fe, Mg, Ti, Ba, and Sr) were higher in the spring and autumn owing to more d.y. with blowing or floating dust. The concentrations of heavy metals were at higher levels in the BTH area by comparison with other studies. In Shijiazhuang
