3.Perseid Meteor ShowerThe Perseids are a prolific meteor shower associated with the comet Swift-Tuttle. The Perseids are so called because the point they appear to come from, called the radiant, lies in the constellation Perseus. Meteor showers occur when Earth moves through a meteor stream. The stream in this case is called the Perseid cloud and it stretches along the orbit of the Comet Swift-Tuttle. The cloud consists of particles ejected by the comet as it passed by the Sun. Most of the dust in the cloud today is approximately a thousand years old.4.Northern LightsProduced by solar winds and the collision of particles in the Earth’s magnetosphere, the eerie spectacle of Aurora Borealis has mesmerised travellers for centuries.5.Southern LightsThe Northern Lights’ counterpart in the southern hemisphere, Aurora Australis has similar properties and can be seen in destinations such as Australasia, South America and Antarctica.6.Tidal rangeThe tidal range is the vertical difference between the highest high tide and the lowest low tide.The world’s biggest tidal differential occurs in the Bay of Fundy in Eastern Canada, where the sea level changes by up to 17 meters (55 feet) during the day. What is generally regarded as the next highest tidal range occurs in the Bristol Channel in the UK, where sea levels change by some 15 meters (49 feet).7.Storm chasingStorm chasing is broadly defined as the pursuit of any severe weather condition, regardless of motive, which can be curiosity, adventure, scientific exploration or for news / media coverage.A person who chases storms is known as a storm chaser, or simply a chaser. While witnessing a tornado is the single biggest objective for most chasers, many chase thunderstorms and delight in seeing cumulonimbus structure, watching a barrage of hail and lightning, and seeing what skyscapes unfold. There are also a smaller number of storm chasers who chase hurricanes.
