Tropical Maritime
What are the conditions;
1. Winter
2. Summer
Cloud and fog type
WINTER
Dull, low cloud, poor visibility
Advection fog
SUMMER
Surface heating, cloud dissipates
Radiation fog
The tropical mariners winter is dull with moving fog
The tropical mariners summer is cloudless with still fog
Tropical Continental
What are the conditions;
1. Stability
2. Summer (temperature and visibility)
- Stable
- Heat wave, poor visibility (Haze)
Whilst warm air can contain more moisture, air parcel travels over land so picks up little moisture so remains stable.
Hazy due to particulates hanging in the air
Polar Continental
What are the conditions;
1. Winter
2. Summer
WINTER
Moist
East coast showers
SUMMER
Cooling effect
Sea fog (Haar)
The Continental polar bear is moist in the east in winter
The Continental polar bear is cool in sea fog in the summer
Polar Maritime
What are the 4 conditions
- Humid
- Unstable
- Moist
- Showers
The Polar Mariner HUMS
What is returning Polar Maritime
- Polar Maritime air mass moves south first over sea
- Picks up moisture
- Heads back inland, heated from below
- Stable lower layer, Unstable upper layer
- Showers and Thunderstorms
Arctic Maritime
What are the conditions
- Mainly dry
- Excellent visibility
- Snow on north coast
- First winter snows (Scotland)
The arctic mariner is dry and can see the snow in scotland
What is Europes predominant winter atmospheric circulation
NORTH ATLANTIC LOW PRESSURE
North Atlantic low pressure path is typically influenced by what
JET STREAM
Continental high pressure in winter
- Which direction does it move
- What does it do to the North Atlantic low pressure system
- What weather conditions (visibility, temp, wind direction)
- May move West
- Blocks incoming North Atlantic Low
- Clear skies, low temperatures, NE, E winds
After a few days, overcast low clouds form, drizzle, and generally gloomy weather
What is Europes predominant atmospheric summer circulation
SOUT ATLANTIC HIGH PRESSURE
