Sub polar low pressure zone happens due to circular shape of earth. The dense , tightly packed air of polar high pressure zone drags southward in Northern Hemisphere at the surface. As they move, they find themselves in a region which is constantly increasing in surface area. Hence they become lighter and starts to spread. This results in a lighter air mass near 50 to 70 degrees N or S forming the low pressure zone. Also as the sun's rays become less oblique in this region, there is more heat generated at the surface making the wind lighter and consequently rise up.

Is CHCl3 polar bond?
I think you have a typo in your molecular formula but CH3Cl is a polar molecule and CCL4 is a non-polar molecule
What is the electrical conductivity of isopropyl alcohol?
It is actually quite low eventhough it is polar.
Is it true that a polar molecule is one that exists only at low temperatures?
This affirmation is not true.
A compound has a very high Rf value in a polar solvent what can you say about its molecular structure?
Rf Value - It tells you the affinity that the compound has to the solvent...High Rf = little or no polar groups and low Rf = more polar groups. Question: In TLC (thin-layer chromatography) when the compound has a high Rf the solvent is: a. less polar b. Is more polar Answer: a. less polar
What are the examples of non-polar covalent compounds?
Essentially, the only totally non polar covalent compounds are the diatomic molecules of single elements. The polarity of all of the hydrocarbons is also very low.
What separates the polar easterlies from the prevailing westerlies?
subpolar low
Major Atmospheric pressure belts?
equatorial low pressure belt sub tropical high pressure belt sub polar low pressure belt polar high pressure belt
What are the 7 components of the general circulation pattern in the atmosphere?
intertropical convergent zones, tade winds, subtropiical highs, westerlies, polar front (sub polar lows), polar easterlies, and polar highs.
Why is there a permanent low pressure belt in the sub-polar region?
the reason is the higher the latidue is the colder the weather it gets
What do low pressure zones at the equator and in sub polar regions cause?
Hurricanes
Which two climatic regions does Alaska have?
Alaska's two climatic regions includes the polar and sub-polar regions. The polar and sub-polar region includes freezing and frigid temperatures.
Where is the subpolar low located?
The sub polar low is located between 50 and 70 degrees latitude in the Northern Hemisphere. These areas have a much more prominent winter season.
What habitats does Alaska have?
arctic, tundra,polar, sub-polar, costal wetlands
Where are the wind belts occur?
they occur in the polar front, the subpolar low, the subtropical high, and the intertropical convergence zone
Location of low pressure systems along fronts and in and at fronts?
When a polar front breaks, into a warm front and a cold front, a low pressure center forms where the break took place. I've provided some links below that show the life cycle of a low pressure system.
What is a pressure belt?
The uneven heating of the earth produces pressure belts. these belts occur at about every 30 degrees latitude. The rotation of the Earth flings the bulk of the air creating an area of low pressure belt in this region.
Which of these climates does precipitation always fall as snow?
Sub-polar.
