What type of conditions lead to light winds that enhance convective currents?

• A. Cool temperatures
• B. Warm summer afternoons
• C. Stormy weather
• D. High pressure

Answer: (B)

Warm summer afternoons create conditions that are characterized by increased solar heating of the Earth's surface. As the sun heats the ground, the air close to the surface also warms up. This warm air, being lighter than the cooler air above it, begins to rise, leading to the development of convective currents. During these afternoons, the winds tend to be relatively light because the temperature gradients are not steep enough to produce strong winds, allowing the buoyancy of the warm rising air to dominate. This process is essential in various atmospheric phenomena, such as the formation of cumulus clouds, which can develop into more significant weather events if conditions are right. The light winds on warm summer afternoons facilitate a stable environment where these convective movements can occur without being disrupted by stronger, conflicting wind patterns, thereby enhancing the overall intensity of the convective currents.
