NASA | Towers in the Tempest

The video discusses the Tropical Rainfall Measuring Mission (TRMM) and its role in observing severe weather, particularly hurricanes. It highlights the discovery of hot towers, towering rain clouds that play a crucial role in hurricane dynamics by accelerating energy movement into high-altitude clouds. The formation of hot towers is linked to wind speed differences and instabilities near the hurricane's eyewall. High-resolution simulations help visualize these processes, showing how hot towers can intensify hurricanes. Despite advancements, forecasting hurricane intensification remains challenging, but combining satellite data with simulations offers valuable insights.

What is the primary tool used to observe weather systems in the first section?

• Ground-based radar

• Weather balloons

• Doppler radar

• Space-based precipitation radar

How do hot towers affect the energy movement within a hurricane?

• They slow down the energy transfer

• They have no effect on energy movement

• They accelerate the movement of energy into high altitude clouds

• They disperse energy evenly throughout the hurricane

What causes the formation of hot towers in hurricanes?

• Rapid changes in wind speeds causing instabilities

• Stable wind speeds

• Cold ocean temperatures

• Lack of moisture in the air

What role does wind shear play in the formation of updrafts in hurricanes?

• It strengthens updrafts uniformly across the hurricane

• It has no effect on updrafts

• It amplifies colliding winds, favoring updrafts on one side

• It weakens all updrafts

Why is forecasting hurricane intensification challenging?

• Because hurricanes are too small to study

• Due to the unpredictable nature of hot towers and their interactions

• Because hurricanes do not change in intensity

• Due to the lack of technology to study hurricanes
