Part 4/9:
Atmospheric rivers play a crucial role in transporting heat and moisture to Antarctica. As these rivers ascend the mountains, the air cools, causing moisture to condense and fall. A surprising outcome of this process is that while temperatures can remain below zero, rain can still occur due to the phenomenon known as "supercooled" liquid water. In Antarctica, this supercooled water can remain in liquid form down to temperatures as low as minus 25 degrees Celsius, resulting in drizzle even in freezing conditions.
