Lightning is an atmospheric discharge of electricity accompanied by thunder, which typically occurs during thunderstorms, and sometimes during volcanic eruptions or dust storms. In the atmospheric electrical discharge, a leader of a bolt of lightning can travel at speeds of 60,000 m/s (130,000 mph), and can reach temperatures approaching 30,000 °C (54,000 °F), hot enough to fuse silica sand into glass channels known as fulgurites which are normally hollow and can extend some distance into the ground. There are some 16 million lightning storms in the world every year.
Sourced from imgbit.com, below is a slow motion gif of a lightning strike.
This striking image taken by Nasa's Terra satellite on 7 January 2010 shows the UK deep in the clutches of a cold snap.
Britain is facing its coldest winter in over 30 years. Heavy snow all over the UK like this is not common, but when it does come, it comes in force.
As the country doesn't normally prepare for such harsh conditions, when the heavy falls arrive it results in chaos with many parts of the country shutting down including schools and public transport with up to 40% or residents not able to get to work.
How is the UK handling all the snow?
The infographic below tells the story. This information and more can be found here at euinfrastructure.com.
Everybody knows that snow is pure white, and most of the time this holds true. However due to a variety of environmental and light conditions, sometimes snow can take on other colours. As you will see snow can be literally be a frozen rainbow!

Violet Snow
Most commonly observed at sunrise or sunset, violet snows occur when trillions of naturally reflective snow crystals amplify and reflect the subtle lavender tint of a twilight sky. This picture is of Venetian gondolas dusted by a rare early evening snowstorm.
Blue Snow
Of all the possible colors, tints and hues snow can take on, blue is perhaps the least incongruous. Clouds, the sea, glacial ice, even our planet from space all appear blue, so the cerulean cast reflected so beautifully by snow appears anything but out of place.
Green Snow
A certain type of algae called Chlamydomonas can tint snow seaweed green. This image was taken in, of all places, Antarctica – pretty much the last place you’d expect to see anything green. Chlamydomonas algae may be unsightly but it’s harmless, and can be found in wintery alpine regions around the world.
Yellow Snow
In February of 2009 snow of an “ugly yellow color” fell in copious amounts. The snowfall was expected as the remnants of a tropical cyclone were due to sweep across the island but the odd color provoked shock and alarm. When melted, the yellow snow was said to leave an oily residue and exuded a “revolting smell”. Analysis of the snow showed above average concentrations of iron and heavy metals, leading Russian scientists to state the smelly snow was contaminated by emissions from power plants and chemical industries upwind.
Pink Snow
Pink snow is not uncommon in chill areas downwind from iron-rich arid or desert regions such as Utah or Colorado in the United States or parts of China east of the Gobi Desert. Rusty reddish dust gets swept into the atmosphere mixing with snow up in clouds, or it may blow on top of fresh snow in a diffuse fashion.
Fulgurites (from the Latin fulgur meaning thunderbolt) are natural hollow glass tubes formed in sand or soil by lightning strikes.
They are formed when lightning with a high temperature of at least instantaneously melts and fuses grains together creatin a hollow tube.
Although lightening strikes last less than a second. The Fulgurites can be left behind and picked up as a reminder. Sometimes it may even fossilise to be found centuries later.
The easiest fulgurites to fond and recover are those that have formed recently in loosely structured sand. The shifting sand makes the fulgurites both easy to see and relatively uncomplicated to remove.
Frost is formed when surfaces are chilled below the dew point of the surrounding air. There are many different kinds of frost such as radiation frost on plants or window frost. It is also capable of causing massive environmental and economic damage. However, in the right circumstances frost can form into beautiful and abstract pieces of art as seen in these images.

When the weather turns bad some photographers may be put off taking shots as they won't obtain the stunning lighting effects they are after.
However, to the resourceful photographer rain presents an opportunity to grab some dramatic or even romantic scenes.
Here are some examples of excellent photographs taken in the rain. They came from SmashingMagazine and you can obtain extra information and find many more beautiful photos here
Winter is the season over the months of June, July and August in the Southern Hemisphere and December, January and February in the Northern Hemisphere. Winter has short days, cold temperatures and especially in the higher latitudes or altitudes, snow and ice.
The colour which defines winter is definitely white.
Here are some shots detailing the beautiful scenes which can be found during this time of year
Thanks to Environmental Graffiti, here are some of the most incredible, interesting and rare light phenomena or events that you may or may not be lucky enough to see in your life time.
Aurora - The collision of electronically charged particles in the earth’s upper atmosphere.
These pictures were taken in Versoix, a town near Geneva in Switzerland.
Very cold conditions, (-8 to -12 deg C, 10 deg F) combined with winds of over 100 km/hr (62 miles/hr) resulted in a spray that froze on anything that it touched! It took place in January 2005. The water is from Lake Geneva (Lake Léman). You can see more photos from the Ice Storm here.
