Dear Guoxiong,dear Jenny:
let me briefly state that my thoughts are with you and your sorrow about the passing away of Prof. YE.
I recall how you, Guoxiong, told me about your old teacher and for some time also dear neighbour.
I also think to remember that Prof. YE was a student of Carl-Gustav ROSSBY's, who himself presided IAMAP back in the 1950s.
So it is a true family story in a wider sense.
Please accept my sincerest condolences, personally and also on behalf of IAMAS.
