Coastal Weather
Coastal weather can be observed in the coastal or oceanic regions. The western coasts of the
continents and the southeastern regions of Australia are characterized with their coastal
climate.
The southeastern Australia is located between the South Pacific Ocean and the Indian Ocean.
One of the most prominent characteristics of coastal weather is that the temperature does not
vary so much with the change of seasons throughout the year in these of these coastal areas.
The climate of marine regions is never extremes.
Hot Weather
Extreme hot weather can be seen in the equatorial regions of the earth. Throughout the year,
the temperature remains very warm in these equatorial locations. The climate in equatorial
regions is also characterized with a very damp and humid weather. The amount of rainfall is
also very high throughout the year. Sometimes the temperature falls a little (only about 3
degrees of Celsius) in the winter months.
Cold Weather
Cold weather can be observed in the polar climate zones. These regions are known for their
extreme cold climates. The temperature remains almost same throughout the year n these Polar
Regions.
Mountain Weather
The weather in the mountainous regions is known as the mountain weather. The climate of
those regions is generally cold enough. New Zealand comes under those high countries that
enjoy the mountain weather conditions.
I'm going to list ten types and I expect you to look through a book or something else (maybe
wikipedia?) to find information that will aid in your own description.
Type 1: Sunny Skies
Type 2: Cloudy Skies
Type 3: Fog
Type 4: Rain
Type 5: Freezing Rain and/orSleet
Type 6: Snow
Type 7: Thunderstorm

Clouds
Weather type 1 - Clouds
There are four basic types of clouds. High clouds,
middle clouds, low clouds, and clouds with verticaldevelopement. There are also clouds that don't fallinto any of these groups.

Dust
Weather type 2 - Dust Storm
Dust storms are created by winds moving across an
arid region. Many times a strong dry cold front is themechanism that creates the dust or sand storm. Asstrong winds move across an arid landscape, sandor dirt is picked up from the ground. Sometimes the
lighter dust particles can be lifted up to 20,000 feethigh into the atmosphere. A classic example of thisis a sand and dust storm that develops over the
Sahara desert. Easterly winds may carry the dust

particles across the Atlantic ocean to the CaribbeanIslands or Florida. Severe sand and dust storms can
obscure visibility to zero and last for days. Picturecourtesy of NOAA, George E. Marsh.
Fog
Weather type 3 - Fog
Fog is a stratus cloud on the ground. There areseveral types of fog. Advection fog is produced by ahortizontal motion of warm moist air over colderground. An example of this would be a warm front

moving across land with a recent snow or coldweather. Radiation fog is produced as heat from the
earth surface is radiated back to space at night. Amoist layer and nearly calm winds need to bepresent. Wind can mix in dryer air aloft, keeping the
air below the saturation point. Steam fog forms
when cold air moves over relatively warm water.This can be observed as wisps of "steam" rising from
lakes, rivers or oceans when a cold air mass movesin. Upslope fog occurs as air is pushed up amountainside and becomes saturated so thatcondensation occurs. Fog photographs courtesy ofRich Johnson and NOAA

Weather type 4 - Freezing Rain / Ice
Freezing rain - known as "ice" occurs when a thinlayer of freezing or below freezing air exists near the
earth's surface. Typically this occurs when snow fallsinto warmer air changing the precipitation into rain.If a very thin layer of freezing air is present near the
ground the rain will freeze on objects such as powerlines, trees, and cars. Ice accumulations begin tocause serious problems when the ice is 1/2" orgreater on objects. Freezing rain pictures courtesy ofNick Stefano.
Hail

Weather type 5 - Hail
The exact processes that creates hail are still being
studied. Traditionally, textbooks showed hailstonesbeing formed as a water droplet was carried aloftwith an updaft into subfreezing air and freezing. As
the ice moved into a downdraft, more water coatedthe hailstone. The cycle continued with the hailstonecontinuing to grow with each ride up and down theupdraft and downdraft.
More recent studies suggest that super cooled waterdroplets are carried aloft by strong updrafts inthunderstorms. A small ice particle forms and grows

as "waves" of supercooled water droplets continueto bump into the ice particle. A new coat of ice
grows with each cycle. The hailstone is kept aloft bythe strong updraft. The stronger the updraft thegreater the force to keep the heavier hailstones
aloft. The hailstone eventually falls to the grown
when the the weight is too great for it to remainaloft or when it gets pushed out of the updraft.
Sometimes hailstones bump into each other whilebeing bombarded with supercooler water dropletsand stick together giving the hailstone a spikedappearance.
The largest known hailstone fell on June 23, 2003 in
Aurora, Nebraska and had a diameter of seveninches and weighed almost one pound. The heaviesthailstone fell in Coffeeville, Kansas on September 3,
1970 and weighed 1.7 pounds. Hail is considered
severe when the diameter reaches one inch orquarter size.

Weather type 8 - Rain
Rain is precipitation in liquid form. Liquidprecipitation can occur as mist, drizzle, or rain.
Droplet size differentiates the type that it isclassified. Mist is generally 50-500 microns in size.Drizzle is .5 to 2 millimeters in size and rain is 2
millimeters to 1 centimenter in size. Rain is formedwhen condensation of water vapor occurs condensesinto water droplets.
Precipitation in the form of rain can be created in anumber of different ways. First, two types ofprocesses cause minute droplets to form rain drops.Collision coalescence is a process where tinydroplets gradually grow in size by bumping into each
other and growing. This is mostly a warm cloudprocess where temperatures are above freezing. Thesecond process is a cold cloud process where super
cooled water droplets freeze on ice nuclei. These icenuclei grow into ice crystals. The snowflakes fall andturn into rain drops as the temperatures go above
freezing. This is the primary process that producesrainfall.
Lifting to produce rainfall occurs in a number ofdiffernt ways. 1. A low pressure system andassociated fronts 2. Mountains or higher terrain 3.
Atmospheric convection

Sleet
Weather type 9 - Sleet
Sleet is transparent frozen raindrops. Sleet or icepellets are created when snow falls into air abovefreezing and melts into rain drops. If another belowfreezing layer below the warm air is of sufficient
depth, the rain drops freeze into balls of ice or icepellets. Any significant amount of sleet is farily rare.This is due to the fact that there needs to be just
the right conditons to get a perfect layer of warm air

in between the layers of cold air. There have beencases of storms producing several inches of sleet. A
mix of snow and sleet and sleet and rain is morecommon. Sleet pictures courtesy of NOAA.
Snow
Weather type 10 - Snow
Snow is the accumulation of crystal snowflakes.Snowflakes are made as water ice crystalizes. Thecrystals may form in many different shapes dictatedby the water content and temperature in the cloud

as the snowflakes are forming. Snowflakes can takethe shape of columns, dendrites, plates, needles and
other six sided shapes. It is possible for it to snowseveral degrees above freezing if the air aloft is verycold and the above freezing layer is shallow near the
ground.
The greatest 24 hour snowfall in North America was
76" Silver Lake, Colo. April 1415, 1921. Thegreatest amount of snow for one storm in NorthAmerica was 189" at Mt. Shasta Ski Bowl, California,Feb. 1319, 1959. The one season snowfall recordfor North America was 1,140" at Mount Baker,Wash. 19981999. Snow pictures courtesy of winter
weather expert Paul Kocin.

Weather type 11 - Sunny
Sunny weather or clear skies is defined as less than
1/8 sky cloud cover. Mostly sunny skies ischaracterized by 1/8 - 2/8 sky cloud cover. Sunnyskies many times are observed when a high
pressure area is dominating the weather pattern.High pressure signifies a region of sinking air whichtends to dry out the atmosphere resulting in lessmositure to form clouds. Deserts are locations withsunny or mostly sunny skies due to high pressuresystems influencing the weather pattern much of theyear.

Weather type 14 - Wind
Wind is the motion of air in the atmosphere. Wind iscaused by an imbalance of heating from the sun.
The uneven heating generates an unbalancedpressure field. Air from a high pressure area flowstoward a region of low pressure to balance the
pressure field. A wind vane points to the directionfrom where the wind is blowing from and ananemometer measures how fast the wind is blowing.
The strongest surface wind gust was 253 mph onAustralia's Barrow Island during Cyclone Olivia in
1996. The previous record was 231 mph record setatop Mount Washington on April 12, 1934.Photographs courtesy of Rich Johnson and the
