If we have extreme and short winter caused by 3-day-eclipse, what would be temperatures like?
Conditions:
Planet is like earth, atmosphere, oceans, ice caps and so, but there is no regular seasons, because axis is made nicely without moon to shake it much.
Double star system (one light and one dark). When stars are in straight line, there is short winter in planet, lets say 3 days (even if its physically though to get such a long eclipse).
So we have 3 days with cca. 1% of sun light. After that, there is summer again and there is no "other" winter in the planet, so temperatures could come back in few days.
Question:
What would be temperatures in day 1, 2 and 3?
What would be sea level in day 1, 2 and 3?
What will be the direction and speed of wind?
My assumptions are this (please do not agree with it :-) ):
Day 1: 10 to 5 degrees - First day of winter is mild, just like longer night
Day 2: 0 to -20
Day 3: -40 to -70 (?)
Could be this fair enough?
Sea levels - because of fact, that volume of ice caps will be much greater till first day of winter, and they will consume lot of ocean water, sea level should be lower from day 1 with strong currents to poles.
Day 1: -0,5m
Day 2: -1m (world ocean is completely frozen to the few metres of depth)
Day 3: -1m (in coastline where all water is frozen and have no space to go lower) to max -3m in open waters
Thanks for clarify and your numbers. Miki
