Question

if typhoon nesat had continued along the same path, which development would most likely have reduced its strength before it hit hanoi?
a the formation of a low - pressure area south of bangkok
b the formation of a high - pressure area south of bangkok
c cool water moving into the sea east of hanoi
d warm water moving into the sea east of hanoi

Explanation:

To determine what reduces a typhoon's strength, we recall that typhoons gain energy from warm ocean water. So, cool water would reduce its energy. Let's analyze each option:

• Option A: A low - pressure area south of Bangkok would not directly reduce the typhoon's strength as typhoons are fueled by warm water, not related to low - pressure in that location.
• Option B: A high - pressure area south of Bangkok also has no direct relation to the typhoon's energy source (warm water) and thus won't reduce its strength.
• Option C: Cool water moving into the sea east of Hanoi would reduce the warm water available for the typhoon to gain energy, thus reducing its strength.
• Option D: Warm water moving into the sea east of Hanoi would provide more energy to the typhoon, increasing its strength rather than reducing it.

Answer:

C. Cool water moving into the sea east of Hanoi
