IN THE CLOUDSBY IVAN

CUMULONIMBUS VARIETIES

THIS IS A CUMULONIMBUS, WITH THE TYPICAL ANVIL - CAUSED BY THE TOP OF THE CLOUD GETTING UP TO THE TROPOPAUSE SO IT CANNOT GO ANY HIGHER, SO THE CLOUD FLATTENS OUT AT THE TOP. THE TOPS ARE COMPOSED OF MILLIONS OF ICE CRYSTALS. THEY CAN GO UP TO ABOUT 10 OR 11 MILES HIGH IN SOME CASES.

CUMULUS CONGESTUS

THIS IS A CUMULUS CONGESTUS SPOTTED IN MILAN. IT STARTS OFF AS AN ORDINARY CUMULUS AND BUILDS UP TO CUMULUS CONGESTUS AND EVENTUALLY CUMULONIMBUS. IT HASN’T GOT IT’S ANVIL TOP YET.

CUMULONIMBUS AND CUMULOS

THIS IS A CUMULONIMBUS WITH A SMALLER ANVIL THAN THE PREVIOUS, SURROUNDED BY CUMULOS. ON THE LEFT HAND SIDE IS FALSE SIRRUS.

CUMULONIMBUS WITHOUT ANVIL

THIS IS A CUMULONIMBUS WITHOUT THE ANVIL AS IT IS NOT PROPERLY DEVELOPED YET BUT IT WILL BE GROWING. THE TOP IS LIKE THE BIG TOP OF A BLOCK WITH CUMULUS CLOUDS SURROUNDING IT.

OPTICAL EFFECTS

SUNDOG OR PARHELIA

THIS SUN DOG IS CREATED BY THE RAYS SHINING THROUGH A SHEET OF ICE CRYSTALS WHICH ARE HEPTAGONAL SHAPE

SUNDOGS AND HALO PHENOMENA

THIS IS A HALO WITH 2 BRILLIANT COLOURS EITHER SIDE OF THE SUN OR THE MOON AND THEY ARE CALLED SUNDOGS OR PARHELIAS.

22 DEGREE HALO

THIS IS A 22 DEGREE HALO WHICH IS A SHEET OF SIROSTRATUS CLOUDS. THEY ARE COMPOSED OF ICE CRYSTALS AND IT IS THE REFRACTION OF THE LIGHT SHINING THROUGH THESE THAT CREATES THE HALO. IT ALSO INDICATES A CHANGE IN THE WEATHER.

GLORY OR BROCKEN SPECTRE

GLORY 1

THIS IS A PHOTO OF A GLORY TAKEN FROM THE SHADE SIDE OF THE PLANE AND FORMED OVER A LAYER OF CLOUD. THE GLORY IS A COLOURED DISK WITH THE SHADOW OF THE SUBJECT IN THE MIDDLE OF IT, WHICH IN THIS CASE IS A PLANE.

GLORY 2

GLORY 2 IS SHOWN FROM A HILL OR A MOUNTAIN SIDE. THE SUNLIGHT IS SHINING THROUGH THE MIST OR FOG. THIS GLORY SHOWS THE SHADOW OF A PERSON IN THE MIDDLE OF IT. IF 2 PEOPLE WERE STANDING TOGETHER THEY WOULD SEE THEIR OWN INDIVIDUAL GLORIES.

SUBSUN

SUBSUN 1

THE SUBSUN IS THE SUN SHINING ON HORIZONTAL ICE CRYSTALS. IT LOOKS LIKE THE SUN IS SHINING DOWN ON TO A MIRROR AND YOU SEE IT FROM THE SUNNY SIDE OF A PLANE.

SUN PILLAR

THIS IS A PHOTO OF A SUN PILLAR AND A HALO. THE SUN PILLAR IS CREATED BY THE RAYS OF THE LIGHT SHINING THROUGH HORIZONTAL SHAPED ICE CRYSTALS.

WEATHER FRONTAL SYSTEMS

ADVANCING WARM FRONT

CIRRUS

THESE ARE CIRRUS CLOUDS AND THEY ARE KNOWN AS MARES TAILS, OWING TO THEIR SHAPE. THIS TYPE OF CLOUD SHOWS AN INDICATION OF A CHANGE IN THE WEATHER IN ABOUT 12 TO 24 HOURS.

CIRROSTRATUS

THIS IS THE SECOND LAYER OF CLOUD WHICH IS CALLED CIRROSTRATUS WITH 22 DEGREES HALO. WHEN PEOPLE SEE THE RING AROUND THE SUN OR MOON, THEY CAN TELL WHEN RAIN OR SNOW WILL COME WITHIN 6 TO 12 HOURS.

ALTOSTRATAS

THIS IS THE THIRD LAYER OF CLOUD OF THE LAYERS OF A WARM FRONT. IT IS A SHEET OF ALTOSTRATUS. IT IS TRANSLUCENT AND SOMETIMES KNOWN AS TRANSLUCENCE AND CAN SHOW A FAINT HALO. IT IS A BIT THICKER THAN THE CIRROSTRATUS.

NIMBOSTRATUS

THIS IS NIMBOSTRATUS. IT IS THE MAIN RAIN OR SNOW BEARING CLOUD. IT IS OFTEN VERY HEAVY, DARK AND LEADEN AND CAN LAST ANY TIME FROM UP TO 24 HOURS PLUS. THE FALLS COULD BE ANYTHING FROM LIGHT TO MODERATE TO HEAVY.

WARM SECTOR

THIS IS 1 OF THE TYPES OF CLOUD THAT YOU SEE AFTER A WARM FRONT HAS PASSED OVER AND IT IS ONE OF THE MOST BORING SKIES AND FEATURELESS AND THE NAME OF IT IS STRATUS.

STRATOCUMULUS

THIS HAS LUMPS, GAPS AND SUN BEAMS AND CREPUSCULAR RAYS SHADOWS. WE OFTEN SEE THESE TYPE OF SKIES ANY TIME OF THE YEAR. YOU OFTEN SEE IT WHEN THERE IS A CLOUDY HIGH.

ADVANCING COLD FRONT

COLD FRONT PASSING OVER

THIS IS A COLD FRONT PASSING OVER. IN THE WINTER THEY CAN BE STRONG ENOUGH TO PRODUCE HEAVY, RAIN HAIL, SLEET AND SNOW. ALSO IF THE FRONT IS EXTREMELY SEVERE IT CAN PRODUCE THUNDER AND LIGHTING.

OCCLUDED FRONT

THIS IS AN OCCLUDED FRONT. IT IS WHEN A COLD FRONT CATCHES UP WITH THE WARM FRONT AND THIS PICTURE SHOWS A VERY ACTIVE OCCLUSION. THIS PICTURE SHOWS WHERE THE OCCLUSION IS PASSING OVER.

ALTOCUMULUS LENTICULARUS

LENTICULARUS VARIETIES INCLUDES SHAPES LIKE CAPS LENSES AND FLYING SAUCERS.

THIS IS A LENTICULARUS, WHICH IS IN THE ALTOCUMULUS FAMILY. BELIEVE IT OR NOT, IT IS OVER HAWAII. IT IS ABOVE A MOUNTAIN OF ABOUT 14000 FEET. ABOVE THE CLOUD THERE IS A UPPER LAYER WHICH I THINK IS CIRRUS OR ALTOSTRATUS.

LENTICULARUS VARIETIES

LENTICULARUS VARIETIES 2

THESE ARE 3 OTHER VARIETIES OF ALTOCUMULUS LENTICULARUS AND THEY ARE ALSO KNOWN AS CAP CLOUDS AS THEY ENVELOP THE TOPS OF HILLS OR MOUNTAINS. THIS IS WHEN THEY HAVE THEIR LIDS ON AS I LIKE TO SAY.

LENTICULARUS VARIETIES 3

HERE IS A CLOUD OVER A HILL OR MOUNTAIN TOP THAT IS ENVELOPED. THIS IS A STRATUS VARIETY.

LENTICULARUS VARIETIES 4

THIS IS A CAP CLOUD AND IT LOOKS VERY MUCH LIKE A SUNHAT. IT HAS ALSO ENVELOPED A MOUNTAIN TOP. THE SURROUNDING SKY IS CLEAR.

STORM FRONTS AND LINE SQUALLES

THIS IS A CUMULONIMBUS SHELF CLOUD WITH VERY HEAVY PRECIPITATION CONSISTING RAIN SLEET HAIL AND SNOW . IT IS SOMETIMES ACCOMPANIED BY THUNDER AND LIGHTNING.

ARCUS AND SHELF CLOUDS

THIS IS A STORM FRONT OF A THUNDER STORM WITH A LIGHTNING STRIKE AND THIS IS THE CUMULONIMBUS FAMILY.

ROLL CLOUDS VARIETIES

SOME ROLL CLOUDS LOOK PLAIN AND OTHER LOOK LIKE ROLLED UP SHEETS OR BANDAGES.

MORNING GLORY

THIS MORING GLORY ROLL CLOUD IS FORMED NEAR COASTAL REGIONS WHERE COLD AIR OVER THE SEA MEETS THE WARM AIR FROM THE LAND. THIS ROLL CLOUD HAS A SPLIT WHERE OTHERS DO NOT

MAMATUS CLOUD 1

MAMATUS 2

THIS IS MAMATUS WITH LIGHTNING. THE MAMATUS IS CREATED BY THE DOWN DRAFT UNDER THE BASE OF A CUMULONIMBUS OR THD ANVIL TOP.

MAN MADE CLOUDS

THIS IS THE STEAM COMING OUT OF THE COOLING TIWERS OF A POWER STATION AND IF THE WEATHER IS COLD ENOUGH THE HEAT CANBESTRONG ENOUGH TO CREATE PYROCUMULUS.

RAINBOWS AND FOG BOWS

THIS IS A FOG BOW WHICH IS CREATED BY THE RAYS OF THE SUN SHINING THROUGH THE MIST OR FOG AND WITH THE WATER DROPLETS BEING SO SMALL IT DOES NOT BREAK UP THE COLOURS AI THE FOG BOW APPEARS WHITE.

FOG BOWS

FOGBOWS ARE LIKE RAINBOWS FUT THEY ARE WHITE BECAUSE THE WATR DROPLETS ARE SO SMALL THEY DO NOT BREAK UP THE COLOURS.

RAINBOW VARIETIES 1

THIS PHOTO WAS LIKELY TAKEN EITHER EARLY MORNING OR LATE EVENING. THIS IS A LITTLE UNUSUAL AS TO THE LEFT OF THE MAIN BOW IS A PEG SHAPED STRUCTURE. IT IS A DOUBLE BOW AND THE PEG IS BETWEEN THE FIRST AND SECONDARY BOW.

RAINBOW VARIETIES 2

THE COLOURS OF THE RAINBOWS ARE CREATED BY THE SUNLIGHT SHINING THROUGH RAINDROPS.

FULL CIRCLE RAINBOWS FROM ABOVE

THESE ARE 2 UNUSUAL PICTURES OF FULL RING RAINBOWS WHICH ARE FROM AN AIRCRAFT BUT I HAVE NOT SEEN IT MYSELF. TO SEE THIS PHENOMENA YOU WOULD HAVE TO BE IN AN AIRPLANE. THE GROUND WOULD HAVE TO BE ABOUT 1000 FT BELOW AND THE CLOUD BASE AT ABOUT 1000 ABOVE THE PLANE.

UNUSUAL CLOUDS

CLOUDS THAT LOOK LIKE THINGS THIS 1 LIKE A CHANDELIER.

UNUSUAL CLOUDS 2

THIS 1 LOOKS LIKE A MUSELLIN CURTAIN

HANGING FROM A LIGHT.

UNUSUAL CLOUDS 3

THIS ANOTHER TYPE OF A CAP CLOUD OF WHICH YOU OFDUN SEE OVER TOPS OF HILLS AND MOUNTAINS FOR EXAMPLE ON THE ISLE OF SKYE.

THUNDER CLOUD

THESE ARROWS ARE TO ILLUSTRATE THE CURRENTS THAT YOU GET IN A THUNDER STORM.

WEATHER SYMBOLS

THESE ARE THE OLD WEATHER SYMBOLS THAT I USED TO KNOW YEARS AGO.

THUNDER CLOUD CONT

THE UP CURRENTS FORCE RAIN INTO VERY COLD AIR CAUSING THE RAIN DROPS TO FREEZE AND TURN INTO HAIL. THE LAYER OF ICE GETS HEAVIER AND EVENTUALLY THE HAIL HITS THE GROUND.

THIS IS THE HAIL SYMBOL

FINE WEATHER SYMBOLS

1) THIS SYMBOL IS OF THE FULL REPRESENTING A SUNNY DAY.

2) THIS FEPRESENTING A CLOUDY DAY WITH NI RAIN OR SNOW

3) THIRD IS PARTLY CLOUDLY WITH SUN OR MOON.

PRECIPITATION SYMBOLS

1) THE FIRST IS RAIN WITH 1 SPOT MEANING SLIGHT TO MODERATE FALL

2) SECOND WITH 2 SPOTS MEANS HEAVY RAIN 3) THIRD REPRESENTS HEAVY SHOWERS AND

SUNSHINE 4) THIS SYMBOL HAS 2 SPOTS 1 RAIN AND THE OTHER

HAS SNOW AND IT IS CALLED SLEET 5) THIS IS A SLEET SHOWER WITH SUN

SEVERE WEATHER SYMBOLS

1) THIS IS A SNOW SYMBOL WHICH IS SLIGHT TO MODERATE FALL

2) THIS IS A SNOW SYMBOL WHICH IS HEAVY FALL

3) THIS IS A SNOW SYMBOL WHICH IS SUNSHINE AND HEAVY TO VERY HEAVY SNOW SHOWERS.

4) THIS IS LIGHTNING 5) THIS IS SUNSHINE AND HEAVY THUNDER

SHOWERS.

TEMPERATURE READINGS

THESE ARE THE TEMPERATURE READING AS THE TEMP GOES UP THE COLOURS GO UP THEY RANGE FROM FREEZING (BLUE) TO VERY HOT (ORANGE, RED).

THIS IS THE END.

THANK YOU FOR WATCHING.

IVAN.
