The night storage heater glows behind the ventilation because it uses electrical resistance to generate heat.

This radiation is then emitted through the ventilation, causing the heater to glow. The ventilation allows for the heat to be distributed more evenly throughout the room. **

Tailwind air turbulences behind trucks refer to the turbulent air flow created by a truck moving at high speed. This turbulent air can affect vehicles driving behind the truck, causing them to experience sudden gusts of wind and potentially lose control of their vehicle. Tailwind air turbulences can be dangerous for drivers as they can lead to accidents, especially on highways or roads with heavy truck traffic. It is important for drivers to be cautious and maintain a safe distance when driving behind trucks to avoid the effects of these air turbulences. **

Tailwind air disturbances behind trucks are caused by the airflow patterns created as a truck moves through the air. These disturbances can create a pocket of low pressure behind the truck, which can pull other vehicles towards the truck. This phenomenon is known as the "bow wave effect" and can be dangerous for vehicles following too closely behind a truck. It is important for drivers to maintain a safe distance to avoid being affected by these tailwind air disturbances. **
