Do all the weather systems form in the ocean?

Question

You hear them on TV all the time, there's a new system coming from Pacific or Atlantic. My question is do all the systems form in the ocean, whether it's storm front or low/high pressure. Do we ever get localized systems that are born, lets say within 24 hours, on localized region away from any water.

Answer 1

Systems can form in any type of place. This is why some systems come through and bring dryer colder air and some bring warm, moist air. They can form over the ocean or over land and can form in any temperature.

Systems can form locally in our country. I saw one day when a system came through and stirred up the atmosphere so much that a new low pressure formed. The main systems though that will raise or drop the temperature and bring significant rains do not form in our general region.

Answer 2

Nope - some form in Washington DC
from all the Hot Air in Congress

sure we do - watch out when a couple of low pressure systems collide
Thunderstorm CENTRAL!

remember the GREAT storm a few winters ago
from Florida to Maine - one continuous squall line -
and moving TOWARD the Atlantic

sooo that was too far to come from the Pacific side

yep - good question

Answer 3

ALANTIC HURRICANES QUITE OFTEN FORM OVER THE AFRICAN DESERT .
