27. Tropical storm is the correct answer as Just before a storm becomes a fully developed hurricane, it is in the tropical storm stage.
28. B is correct
mT maritime tropical is warm, moist, usually unstable
cP continental polar cold, dry, stable
cT continental tropical hot, dry, stable air aloft unstable surface air
mP maritime polar cool, moist, and unstable
29.OPtion C is correct as Supercell thunderstorm is characterised by intense concentration of downburst wind
30. B is correct As Observations show that no hurricanes form within 5 degrees latitude of theequator.
31. Option C is correct
The leading edge of a thunderstorm's cold downdraft is known as a Gust front
