2. What is a Heat Wave
a prolonged period of abnormally hot weather.

3. Heat Wave is
In the past 3-4 decades, there has been an increasing trend in high-humidity heat waves, which are characterized by the persistence of extremely high night-time temperature. The combination of high humidity and high night- time temperature can make for a deadly pairing, offering no relief and posing a particular threat for the elderly. Extreme heat events are responsible for more deaths annually than hurricanes, lightning, tornadoes, floods, and earthquakes combined

4. what does heat waves involve
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 parts of India. Heat Waves typically occur between March and June, and in some rare cases even extend till July. The extreme temperatures and resultant atmospheric conditions adversely affect people living in these regions as they cause physiological stress, sometimes resulting in death.

5. what causes a heat wave
A heat wave is a period of unusually hot or humid weather that lasts at least two or three days – and remaining hot throughout the nights – that affects large areas. Heat waves are caused by a system of higher atmospheric pressure, whereby air from upper levels of the atmosphere descends and rotates out.

6. One incident a heat wave occurred
In May 2015, India was struck by a severe heat wave. As of 3 June 2015, it has caused the deaths of at least 2,500 people in multiple regions. The heat wave occurred during the Indian dry season, which typically lasts from March to July with peak temperatures in April and May. Although it typically remains hot until late October, Indian monsoons often provide some respite from the heat.

7. The effect of heat waves on biodiversity
Climate change poses a significant challenge to all natural systems on Earth. Especially increases in extreme weather events such as heat waves have the potential to strongly affect biodiversity, though their effects are poorly understood due to a lack of empirical data. Therefore, we here explore the sensitivity of a tropical ectoderm, which are in general believed to have a low warming tolerance, to experimentally simulated climate change using ecologically realistic diurnal temperature cycles.
