2 2010 Pakistan floods 2011 - Hauz et.al., Webster et. al., Hong et. al, Lau and Kim, Saeed et. al.

3 TRMM Rainfall anomalies for JJAS 2010 (mm) Clim+ 0.5 σ Hong et al. (GRL, 2011)

4 TRMM (Rainfall) and NCEP (Moisture Transport) JJAS Climatology TRMM (Rainfall) and NCEP (Moisture Transport) “2010” JJAS Anomalies

5 Asian summer monsoon response to La Nina events under warming climate Mujumdar et al. (2012) - Meteorological Applications Special issue on Asian summer monsoon Composite SST anomaly (12 La Nina cases ) (mm) ( 0 C) NCEP OI-SST Anomaly for JJAS 2010 ( 0 C)

6 JJAS mean sea level pressure (hPa) 2010 CLIM (JJAS mslp 2010) – (cmp La nina) Anomalies hPa

7 2010 JJAS OLR anomalies Composite of olr anomaly (La Nina)

8 Zonal Circulation Red : Climatology Black : 2010 Anomalous Zonal Circulation : 2010 Averaged over 10N-20N

9 La Niña events 2010 Total – 20 / JJAS - 12 Total – 45 / JJAS > 30 Rainfall - ~ 108% of LPA Rainfall - ~ 101% of LPA Extended Analysis

10 Averaged Rainfall over Indo-Pak region (65-76 E; 28-36 N) during JJAS Intense Rainfall events Accumulated La Nina event

11 EOF-MSLP-JJAS PC1

12 b) without ENSO component a) with ENSO component SST anomaly for JJAS 2010

13 LMDZ-AGCM “CLIM” ensemble JJAS mean Rainfall and moisture transport LMDZ-AGCM “2010” ensemble JJAS anomalies Rainfall and moisture transport

14 LMDZ-AGCM “2010” ensemble JJAS mean Rainfall and moisture transport LMDZ-AGCM “with ENSO” ensemble JJAS anomalies (Excluding SST warming trend) Rainfall and moisture transport

15 LMDZ-AGCM “without La Nina” JJAS anomalies (retaining Indian ocean warming trend) Rainfall and moisture transport LMDZ-AGCM “2010” ensemble JJAS anomalies Rainfall and moisture transport

17 Summary 1.West ward shift of WPSH - Asian summer monsoon response to La Nina events under warming climate. 2.Westward shift of monsoon circulation and large-scale suppression of convection over Indo-Pacific sector during La Nina episodes. 3.Northward transport of moisture over northwest Indo-Pak region from Indian Ocean 4. Complex interactions between tropical and sub-tropical circulations – extreme rainfall events over subtropical Indo-Pak region. Scope for future work Ensemble simulation experiments for understanding the role of La Nina episodes under warming climate in the evolution of heavy flood events over South Asia.
