The simulations reveal a seasonal water \"pump\" mechanism responsible for the upward transport of water vapor. This mechanism occurs in high latitudes above 60$^\\circ$ of the southern hemisphere at perihelion, when the upward branch of the meridional circulation is particularly strong. A combination of the mean vertical flux with variations induced by solar tides facilitates penetration of water across the \"bottleneck\" at approximately 60 km.
