The sparse distribution of the feathers, however, also allows considerable lateral air movement over the skin surface, thereby permitting further heat loss by convection.
然而，羽毛的稀疏分布也使得皮肤表面形成相当大量的侧向空气流动，从而可以通过对流进一步散热。

Convection within the red giant dredges the new proto-dust atoms from the core up to the surface.
红巨星内部的对流碰撞出新的原始尘埃原子会从其核心撞到表面。

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.
