A wave forms in a series of crests and troughs. The crests are the peak heights of the wave and the troughs are the lowest valleys. A wave is described by its wavelength (or the distance between two sequential crests or two sequential troughs), the wave period (or the time it takes a wave to travel the wavelength), and the wave frequency (the number of wave crests that pass by a fixed location in a given amount of time). When a wave travels, it is passing through the water, but the water barely travels, rather it moves in a circular motion.

What is a heat wave?
  • A heat wave is a period of abnormally high temperatures, more than the normal maximum temperature that occurs during the summer season in the North-Western and South Central parts of India.
  • Heat waves typically occur between March and June, and in some rare cases even extend till July.
  • Higher daily peak temperatures and longer, more intense heat waves are becoming increasingly frequent globally due to climate change.
  • Conditions for Heat wave according to the IMD:
    • A region deviating from its ambient temperature by atleast 4.56.4° C from the longterm average has a heat wave.
    • For Plains, there is also a heat wave if the maximum temperature crosses 45°C.
    • At a hillstation, if the maximum temperature crosses 37°C, it is considered to be heat wave condition.
How do heat waves occur and its Impacts?
  • Heat waves is a local phenomenon when the air is warmed by higher land surface temperature or because the air sinking down from above is compressed along the way, producing hot air near the surface.
  • Generally, heat waves occurs due to the following reasons:
    • Warmer air flowing in from elsewhere
    • Warm air being produced locally
  • Health Impacts
    • The health impacts of Heat Waves typically involve dehydration, heat cramps, heat exhaustion and/or heat stroke.
    • It also causes heat cramps, fatigue, weakness, dizziness, headache, nausea, vomiting, muscle cramps and sweating.
    • The extreme temperatures and resultant atmospheric conditions adversely affect people living in these regions as they cause physiological stress, sometimes resulting in death.
FAQs Related Waves and Heat Waves
Ques 1. What is the difference between waves in the ocean and heat waves?

Ans. Waves in the ocean refer to disturbances on the water surface caused by wind, tides, or seismic activity. They have a regular pattern and can travel across the ocean. On the other hand, heat waves are prolonged periods of excessively hot weather conditions on land, characterized by high temperatures, often accompanied by high humidity and lack of precipitation.

Ques 2. How are waves in the ocean related to weather patterns and climate?

Ans. Ocean waves are linked to weather and climate, influenced by wind patterns, atmospheric pressure, and Earth’s rotation. Understanding them is vital for predicting weather, monitoring erosion, and studying climate dynamics.

Ques 3. What are the impacts of heat waves on human health and the environment?

Ans. Heat waves impact human health and the environment, causing heat-related illnesses, reduced agricultural productivity, wildfires, and wildlife mortality. Adequate preparation and mitigation strategies are crucial to minimize these impacts.
