As it’s halloween tomorrow, we’ve taken a look at the top ten spookiest weather conditions. From well known scary weather – like thunder and lightning and sea mist, to lesser-known phenomena such as brocken spectre and fall streak holes.
- Fall streak hole. Also known as a hole punch cloud, these clouds sometimes cause people to think the world is ending, especially when wispy vigra clouds are descending from the hole. The exact conditions that cause them to occur are still debated.
- Sea mist. This occurs when mild air moves over the sea, which is cooler. It can be particularly spooky when sea mist comes in during the day and visibility is drastically reduced.
- Sunsets. Although often considered beautiful, some particularly vibrant red sunsets can create a spooky effect.
- Dust storms. Dust and sand storms can be whipped up rapidly by strong winds in arid regions. Dust storms can look particularly ominous as they approach as they can be up to 40 metres high.
- Whistling wind. Windy conditions can be scary when they blow through objects causing a whistling sound.
- Brocken spectre. This effect is produced when an observer stands above the upper surface of a cloud – on a mountain or high ground – with the sun behind them. When they view their shadow the light is reflected back in such a way that a spooky circular ‘glory’ appears around the point directly opposite the sun.
- Roll clouds. These ominous looking clouds are a type of arcus cloud usually associated with a thunderstorm or a cold front. As these rare clouds often appear to be ‘rolling’ they often cause fear that severe weather is on the way.
- Thunder and lightning. One of the most common forms of ‘scary weather’, thousands of thunderstorms are taking place at any one time across the globe. The lightning you see during a thunderstorm is a large electrical spark caused by electrons moving from one place to another, while the rumble of thunder is caused by the noise of intense heating and expansion of the air along the path of the lightning.
- Clouds over a full moon. This spooky effect occurs when clouds partially cover a full moon.
- Fog. Fog forms when relatively moist and mild air close to the ground cools quickly, causing the moisture in the air to condense (at which point it becomes visible to the human eye). This normally happens in autumn and winter under clear skies, which allows heat from the ground to escape quickly to cause rapid temperature drops.
