I have been stuggling with this task for a while myself. When you clever
ones nut it out, please publish a "Fade an Image to transparent" and "fade
an image to white" tutorial "for complete idiots" (aka me)

Those are basically two layers: On the bottom layer there's the blue (in 
your case,
green) gradient, the snowflakes are on a transparent second layer. To 
achieve the
transitional effect, apply a black-to-white gradient as a layer mask to 
the snowflakes
layer ('Layers > Add Layer Mask', with the default setting; then apply 
the black-to-white
gradient to this layer, and as a third step, 'Apply Layer Mask'. 
Finally, merge the two
layers with 'Flatten Image' or CTRL+M (Merge Visible Layers). That's 
basically it.
