I'm with Rwood (Ice / water ratio)

Deano · « **Reply #41 on:** September 28, 2012, 07:09:57 AM »

Is it weight?

Weather Display · « **Reply #42 on:** September 28, 2012, 07:24:26 AM »

graupel is also called ice pellets

its rain that has frozen near the ground

I think

As far as i under stand it Hail is rain drops that have been frozen.
sleet is snow that is melting as it goes though air this is above freezing.
graupel is sleet that-has refrozen as it falls though a layer of air colder than 0c.

Grauple is snow (crystal) around which (hoar) frost has grown. ie. it has a 'soft' center.

Some good answers. Here is the one I had from the NOAA website:

Quote

The different ways precipitation is formed determines what type of precipitation it becomes. Hail is larger than sleet, and forms only in thunderstorms. Hail formation requires air moving up (thunderstorm updraft) that keep the pieces of ice from falling. Drops of supercooled water hit the ice and freeze on it, causing it to grow. When the hailstone becomes too heavy for the updraft to keep it aloft, or it encounters downdraft air, it falls. Sleet forms from raindrops that freeze on their way down through a cloud. Snow forms mainly when water vapor turns to ice without going through the liquid stage. There is no thunderstorm updraft involved in either of these processes

Unfortunately it didn't mention graupel, but the trusty glossary on the NOAA site says:

Quote

GRAUPEL - A small white ice particle that falls as precipitation and breaks apart easily when it lands on a surface. Also called soft hail or snow pellets, graupel retains a soft structure and surface, and forms when snow flakes partially melt on falling into warmer air and then re-freeze on passing back into colder air.

After all those pints things are starting to get messy, so for this round, pints (points) for all.

Q for tonight - Which characters in Shakespeares Macbeth, say the following famous lines:

When shall we three meet again
In thunder, lightning, or in rain?

When the hurlyburly's done,
When the battle's lost and won.

“Fair is foul, and foul is fair:
Hover through the fog and filthy air.”

The witches!

The three witches (aka Weird Sisters)

Witch #1
"When shall we three meet again
In thunder, lightning, or in rain?"

Witch #2
"When the hurlyburly's done,
When the battle's lost and won."

All three
“Fair is foul, and foul is fair:
Hover through the fog and filthy air.”

Ah - well done guys but the pints go to Deano this time!

Last night was too easy. Have a go at this one:

Q: What is a Derecho?

Weather Display · « **Reply #50 on:** September 30, 2012, 08:27:13 AM »

they had a big one recently in the USA
its like a conglomeration of thunderstorms
will start out as a squall line, which has a bow echo in font
which then gets larger and stronger
and can last a long time
has destructive straight line winds....outflow winds in front of the squall line

something like that

gabba · « **Reply #51 on:** September 30, 2012, 06:46:22 PM »

Well done Weather Display!

Answer to last nights question:

A derecho is a widespread thunderstorm wind event caused when new thunderstorms form along the leading edge of an outflow boundary (a surface boundary formed by the horizontal spreading of thunderstorm-cooled air). The thunderstorms feed on this boundary and continue to reproduce themselves. Derechos typically occur in the summer months when complexes of thunderstorms form over the plains and northern plains states. Usually these thunderstorms produce heavy rain and severe wind reports as they rumble across several states during the night. The word "derecho" is of Spanish origin and means "straight ahead". They are particularly dangerous because the damaging winds can last a long time and can cover such a large area.

Tonights question:
"The Wind in the Willows" is a classic of children's literature by Kenneth Grahame, first published in 1908.
Name the 4 main characters that make up this story.

TokWW · « **Reply #52 on:** September 30, 2012, 07:43:39 PM »

Christopher Robin, Piglet, Pooh Bear and Eee-Yore? I think...

gabba · « **Reply #53 on:** September 30, 2012, 09:39:28 PM »

Haha - my kids could come up with that answer - but that's because we watch lots more pooh than wind

TokWW · « **Reply #54 on:** October 01, 2012, 01:04:25 PM »

There was Tigger as well, perhaps more...

Ok - here's tonights puzzler. There are multiple questions:

Qa: What is considered the worst air pollution event in London's history, and when did it occur
Qb: What was the cause of this event, both physically and meteorologically
Qc: How many people is it estimated to have killed (a reasonable guess or range would be okay here)

Answers to one or all of the above are acceptable - or have a guess! Have fun!

It was the great smog event of December 1952. Presumably there was a very stable inversion lasting several days.
