Why doesn the places in the equator experience heat waves???
A heatwave is generally a prolonged period of unusally hot weather. ‘Hot’ is subjective as it depends on what the weather is normally like. Where I am (the UK) a heatwave would be anything upwards of about 33°C that lasted more than a couple of days but in other parts of the world this type of weather is the norm. Living close to the equator you’ll be used to hot weather. If you’d have been in the UK today you’d probably have felt cold whilst the rest of us were wandering around in T-shirts because to us it was hot. In a country like Japan where the weather is generally more moderate, people aren’t used to the heat and when the temps rise people are unable to cope – particularly the elderly, very young and the infirm. In short, it’s a matter of perception.
