When Venus Express started operations in 2006, high-altitude winds between latitudes 50 degrees either side of the equator were recorded at about 300 kilometres (187 miles) per hour on average, they found. These winds have progressively increased and now are running at almost 400 kph (250 mph).

n the video above, the temperature of the air is much colder than the temperature of the water. The water in the lake has yet to freeze. The freezing air has very little water vapor in it (that's why it's so dry). The lower the temperature gets, the less water vapor can stay in the air. The point at which water in it's gas form turns into liquid water is called the dew point. This interaction between the temperature and water and the dew point is how you gets things like clouds, fog, dew on the ground, frost, etc.
