BajishD2 <br> LvPatterns of multi-decadal variability of Antarctic Sea Ice Extent revealed by Satellite observation and CGCM output<br> e<br> The longterm sea ice variability patterns in the Southern Ocean is investigated using model data(CFES MINI). Compared to the satellite winter mean sea ice extent(SIE), the model mean winter SIE had been reproduced exactly to certain extent. The model mean winter sea ice concentration(SIC) is under estimated compared to the mean winter SIC derived from the satellite. In line with the previous studies, the temporal and spatial patterns of the leading modes of the empirical orthogonal function(EOF) of the observed SIC can be associated with the Southern Annular Mode(SAM)/Antarctic oscillation(AAO) and Pacific South American(PSA) teleconnection pattern. The leading modes of model geopotential height(Z) also shows a spatial pattern similar to SAM and PSA. The power spectral analysis of the principle components(PC) of the leading modes of Z, SIC and sea surface temperature(SST) revealed signals of decadal variability. There is high correlation between the PC's of the leading modes model SST and SIC. Hence, the variability in the ocean plays an prominent role in the longterm variability of sea ice in the Southern Ocean. </td> </tr> <tr> <td>eBf2011t^ 5g25e(4l) 15:00-17:00<br> 4X@bNO)nx0xvzh2F Op[<br> zvh7S .YM2 <br> LvؚP^wm m000k000WS'Y mf4lS00000n0f<br> e<br> яt^0WS'Y mk0J0Q00wm4l)nn0 NfL0UWg0B00Gille.2008 0]0n0;Nj0 Vo000Wt)nfSk04OF0'Yl YR(Southern Annular Mode; SAM)k0B00 Thompson and Solomon., 2002 0WS'Y m Nn0OPn0uieTx0n0wyk04OF0WSuihTuiAm(ACC)n0wySokolov & Rintoul.,2009 00OPn0R7_Sk04OF0&nKRn0;mzvSk000uieTx0n0q8Meredith and Hogg., 2006 L000000h0W0f0:yUU00f0D000W0K0W00S000n000000o0ASRk0f0K0k0U00f0D0j0D00]0S0g00,gxvzg0o0яt^lvU00f0D00_n000000k0@wvW00wm m'Y_t000000(OFES)0(uD0f00WSuihTuiAmWn0&n;mRk0[Y00Q4l)nn0_T{yr'`0f0K0k0Y00S0h00vvh0Y000<br> ,gxvzg0o00[fwmbؚ^g0IcH000_0&n;mRn0 YR4Xh0wm m'Y_t000g0n0&n;mRn0 YR4X0kW00000n0Qs'`0xY000]0W0f000000000(uD0f0&n;mRk0[Y00Q4l)n_T{yr'`0fY000<br> </td> </tr> <tr> <td>eBf2010t^10g06e(4l) 15:00-17:00<br> 4X@bNO)nx0xvzh2F Op[<br> zvh_lm vNYec <br> Lv[fؚ^k00000000wmqgn0hd\_tn0,n<br> e<br> TOPEX/Poseidon, Jasoon-1, -2 n0Wn0[fؚ^g0,nU00_017t^Rn00000㉐gW0000000wmqgn0hd\_tn0c[{ YR0L}t^ YR0f0K0k0Y00S0h00f0_00gen0̎SlD0wmbؚ^OP]000000g0o00noPl000j0i0L0feU00f0D00h0h00k0000wm\яO0n0000L0_00f0D000noPl܈ckn0]k0000000000n0q_0T㉐g0(uD0f0S0dD0_000000000lg0S0n0܈ckn0Rg0y0_0h0S000EmwmW0l\WNYg0o00P}gh0W0f0noPldSo0B0~00RD0f0j0D0S0h0L0RK0c0_00noPl000n09eoL020g0D00_00h0H00000ؚ^000o00000000JS\\n0S NAm0qg\0WS NY00qg000000wmAmk0[_Y00wmbؚ^OP]n0c[{ YR0L}t^ YR00O0IcH0f0D00S0h0L0:yU00_00 000000\S NAmh0qg000000wmAmn0c[{ YR0L}t^ YRo0ND0k00O0NY000~0_00CS\R\n0wm\n04lMO]n0c[{ YR0L}t^ YR0ؚ^000g0IcH000f0D00S'`L0:yU00_00c[{ YR0L}t^ YRh000000000\S NAmJ00s0qg000000wmAmk0[W0f00Chetertyy Kuril skiy wm\o0 TMOv0Kruzenshternawm\o01_D0 TMOv0Bussol wm\o0^8^k01_D0MOv0Fritzawm\o0MOv n0 YR0:yW0_0~0_0 000000\S NAm0qg000000wmAm0J00s0CS\R\n0Twm\n04lMOOP]h0S*Ys^ mJ00s000000n0wm N4Xn0 YRh0n0[_0c[{ YR0L}t^ YRk0d0D0f000_00 </td> </tr> </TBODY> </TABLE> </center> <BR><br> <A href="seminar2010.html"><FONT color="purple">2010t^^uiW0000</FONT></A><br> <A href="seminar2009.html"><FONT color="purple">2009t^^uiW0000</FONT></A><br> <A href="seminar2008.html"><FONT color="purple">2008t^^uiW0000</FONT></A><br> <A href="seminar2007.html"><FONT color="purple">2007t^^uiW0000</FONT></A><br><br><br> <TABLE border="2" bgcolor="lightgreen"><TBODY> <TR><TD><A href="index.html"><FONT color="purple">to Home</FONT></A></TD></TR> </TBODY></TABLE> <center><FONT size="-1">Copyright 2007 S'YNO)nx'Ylwm mvN\O(uRΑ</FONT></center> <HR> <ADDRESS><IMG src="home_img.gif" width="86" height="60" border="0" align="left" hspace="20">Contact address<BR> aos"at"lowtem.hokudai.ac.jp</ADDRESS> </BODY> </HTML>
