  1. Targeted Training Activity (TTA) on “ENSO Monsoon in the Current and Future Climate” Analysis of Bangladesh Climate in perspective of CMIP5 Models Group: South Asia B Bazlu, Khaled, Ashfaqur, Adnan, Zahid, Vivek, Azhar & Hasan

  2. GEOGRAPHY OF BANGLADESH • Bangladesh is vulnerable due to its position in the globe(South east Asian country) of area • about 147,570 sq. Km. • Lat: 20°45' to 26°40'N • Long: 88°05' to 92°40’E • Bangladesh is a land of about 230 rivers. • But its 57 rivers originate from outside. • The major rivers-Meghna, Jumana Padma and Brahmaputra.

  3. CLIMATE OF BANGLADESHTotal Annual Rainfall = 2400 mm

  4. Methodology • JJAS season has been selected for the following models • Region is Bangladesh [87.5:93.5E; 20.5:27.0N]

  5. Temperature

  6. JJAS Climatology: Temperature (°C)

  7. Variability of the Surface temperature

  8. Annual Cycle: Temperature (°C)

  9. Rainfall

  10. JJAS Climatology: Rainfall (mm/day)

  11. Annual Cycle:Rainfall (mm/day)

  12. Inter-annual variability of Rainfall 87.5:93.5E; 20.5:27.0N

  13. Correlation of Nino3.4 Index with Rainfall:Historical Period

  14. Future Projection

  15. Difference of Std for the future period 2075-2100 w.r.t base 1980-2005

  16. % Change of the rainfall for the period 2075-2100 w.r.t 1980-2005

  17. Conclusions • CNRM is a good model for simulating Rainfall very well. • HadGEM, is different from the other models in future projections. • All the models are showing increase of rainfall over Bangladesh and the temperature variability in the tropical pacific except HadGEM in future.
