Second interview no harder than the first, pot luck with questions.
Typhoons: look it up on wikipedia, 26.5 degrees surface temp, 5-20 degrees lat, etc....req'd for formation, move westerly, then pole-ward due to stronger coriolis on polar side. Re-curve to the east across the sub-trop ridge. get their energy from latent heat of condensation, last around 10 days, wind spead greater than 64 kts off hand.
Enjoy.
Oh, Carbon brakes a good question at interview too.
