我无休止地花钱买昂贵的东西，所以开支趋向上升。

I spend money on expensive things endlessly; so the expenditure trends up.

假设地表降温而其上的空气升温，那么地表的空气要向上升腾就变得不那么容易；而对流减少导致的将会是趋向于减少的云层生成和降雨。

If the surface is cooled and the air above it warmed, there is less tendency for air from near the surface to rise; reduced convection will tend to lead to fewer clouds and reduced rainfall.
