The interaction of the downward Kelvin waves with the QBO.

QBO bases

1. QBO Map and indexs.
2. QBO Histograms at different pressure levels.

Kelvin wave at different zonal wind background .

1. Climatological maps

Varying zonal wind	Varying Shear	Varying zonal wind + shear
Height-Longitude maps	row 1 column2	row 1 column3
Latitude-Longitude maps (50hPa, 50hPa)	Latitude-Longitude maps (50hPa, 50hPa, 30-50hPa)	row 2 column3
