Once that heat release has cooled the ocean to its freezingtemperature, sea ice forms again.
一旦释放出的热量足够多，使海洋达到自己的冰点，海冰又会重新形成。

So you can actually get the water to be below the freezingtemperature and it won't freeze yet.
这样水就，处在冰点温度以下，水不会马上结冰。

These clouds occur within cirrostratus clouds, which are often composed of ice crystals and drops of water that are below freezingtemperature but still in liquid form.
