Since the tropopauses of these planets are very cold, there is effectively a cold trap, which in the absence of any other sources should keep the stratospheric water abundance very low, as discussed in Section 4.3.3.The heat input to polar areas prevents this global cold trap catastrophe from happening, but during ice ages, significant capture of the Earth’s water in polar areas will occur.
Cold Traps for Vacuum
A demountable reservoir-type, liquid nitrogen cold trap designed for use with a rotary vane mechanical pump. Since the trapping of water and oil vapor is so complete and irreversible at liquid nitrogen temperatures, base vacuum in the high 10 -6 Torr range can be achieved.
The cold trap pictured, uses the center sprue to deliver the butane at low pressure underneath the cooling coils, so it bubbles up around them, and they are kept cold by pumping coolant through the coils and setting the whole thing in coolant.. The trap that I uses

In this function, they are called a cryotrap, waterpump or cold trap, even though the physical mechanism is the same as for a cryopump. Cryotrapping can also refer to a somewhat different effect, where molecules will increase their residence time on a cold surface without actually freezing ( supercooling ).
