Respuesta :
What type of severe weather, direction the weather, any significant weather that may cause death or property destruction, and what areas will be affected by the severe weather is the information that is required for advance warnings of severe weather conditions.
Answer:
Changes in atmospheric pressure and wind velocities.
Explanation:
Destructive weather patterns like hurricanes, cyclones, and tornadoes are characterized by one thing - a sudden rise or drop in atmospheric pressure. Another significant contribution is the wind velocity. However, the latter is dependent on the former as the wind speed is as a result of a change in pressure.
A sudden lowering of pressure creates a zone of intersection between the two clouds or air zones. This increases the atmospheric pressure. However, the region in the middle of a disaster, say tornado, has a low pressure. The sudden increase in pressure should be a warning sign of a disaster.
