Good bye year 2016. Hello year 2017.
We all know that 2017 is a prime number, but it is more than just another prime number.

The World's Greatest Fish Migration - The South African Sardine Run

Fwd: Some really interesting weather images.

Some really interesting images

1.

Brinicle

Brinicles
are the underwater equivalent of icicles. A brine from the sea ice sinks, a 'brinicle' forms threatening life on the sea floorwith a frosty fate.

2.
Volcanic lightning

Volcanic
plumes produce immense amounts of electrical charge and static.

In rare cases, this can spark a violent lightning storm.

3.
Sprites, Elves and Blue Jets

These
colourful shapes are the result of electrical discharges in the atmosphere.

4.
Fire Rainbows

Fire
Rainbows are formed by light reflecting from ice crystals in high level
clouds.The halos are so large, they often appear parallel to the horizon.

5.
White rainbows

These
rainbows form in fog, rather than rain.The condensation reflects little light,
and as a result, the rainbow is made up of very weak colors like white rather
than the vibrant colors of a traditional rainbow.

6.
Fire Whirls

Fire
whirls are whirlwinds of flame.They occur when intense heat and turbulent wind
conditions combine.

7.
Catatumbo Lightning

At
the mouth of the Catatumbo River in Venezuela, a very unique mass of storm
clouds swirl, creating the rare spectacle known as Catatumbo lightning. The
storm occurs up to 160 nights a year, 10 hours per day and 280 times an
hour.

8.
Moonbow

Moonbows
are rainbows produced by light reflected off the surface of the
moon,rather than the sun. Due to the small amount of light reflected off the moon, moonbows are quite faint.

9.
Glory

A
glory is an optical phenomenon, similar to a rainbow, that resembles a
halo. It occurs when light tunnels through air inside rain droplets and emit the light
backwards. Yes, that's as crazy as it sounds

10.
Waterspouts

Waterspouts
are vortexes, which occur over a body of water. No water is sucked in and the
spout is made entirely from water given off by condensation.

11.
Morning Glory

Morning
Glory clouds are incredibly rare, so much so, that we don't
know what causes them. They're most commonly seen at fall in the small town of Burketown in Australia .

12.
Lenticular Clouds

Lenticular
clouds are lens-shaped clouds that form when moist air flows over a mountain and
piles into large and layered clouds. Due to their strange shape, these clouds
are often mistaken for UFOs

13.
Penitentes

Penitentes
are tall, thin blades of hardened snow and ice that form at high altitudes. At
such a height, the sun’s rays are able to turn ice into water vapor without
melting it first. Some areas randomly turn into vapor more quickly than others,
forming depressions in the smooth surface. Over time, they transform into jagged
fields which face the same direction as the sun.

14.
Supercells

Supercells
are the rarest and most dangerous type of storms. While they are formed just
like other storms, the vertical rotation of their updraft means that they can
sustain themselves for far longer.

15.
Frost Flowers

Frost
flowers are formed when sap in the stem of plants freezes and expands, cracking
the stem. Water then draws through the cracks and freezes upon contact with the
air, eventually forming exquisite patterns.

16.
Sun Dogs

Sun
dogs are an atmospheric phenomenon that occur when ice crystals cause light to
appear brighter when the sun is at a certain angle

17.
Mammatus Clouds

Mammatus
clouds are cloud pouches that form and hang underneath the base of a cloud. When
air and clouds holding different levels of moisture mix, the heavier one sinks
below the lighter.

18.
Snow Donuts

Snow
donuts are formed when chunks of snow are blown along the ground by wind,
picking up material along the way. The inner layers are weak and can easily blow
away, leaving a donut.

19.
Belt of Venus
