Question

Identify the incorrect statement regarding extreme temperatures:

1. Both heat waves and cold waves describe periods of temperature extremes that are always relative to global average temperatures, not local climate patterns.
2. A heat wave is defined by excessively hot and often humid weather, while a cold wave involves unusually cold weather or a sudden influx of cold air.
3. Winter storms, often accompanying cold waves, are primarily associated with drought conditions.

Answer 1

Answer:

B. ii മാത്രം

Extreme temperature events, whether heat waves or cold waves, are fundamentally understood in the context of a region's typical climate. What is extreme in one climate zone might be normal in another. Thus, statements suggesting these are always relative to global averages or that winter storms are linked to drought are incorrect. Winter storms are characterized by significant precipitation (snow, ice, or rain) and cold, leading to hazards like flooding and transportation disruptions, not drought. Understanding the local context is crucial for defining and responding to these events effectively.
