Why winter in the northern hemisphere is much colder and snowier than winter in the southern hemisphere?

Bentornati ad un’altra eccezionale edizione delle domande di cultura generale!

2054 utenti della rete avevano questa curiosità: Spiegami: Why winter in the northern hemisphere is much colder and snowier than winter in the southern hemisphere?

To clarify, I’m asking why when it is winter IN the southern hemisphere, why is it milder than winters in the northern.

Not asking why are the seasons reversed.

Ed ecco le risposte:

There’s just more land in the Northern Hemisphere. Most of the land in the Southern Hemisphere is close to the equator. There are places that are far from the equator that do get cold and snowy winters, like Patagonia in Argentina or the South Island of New Zealand… and (obviously) Antarctica.

Sydney, Australia is only at 33°S. The equivalent latitude in the Northern Hemisphere splits the US states of Arkansas and Louisiana. Those places don’t get cold and snowy winters either.

Look at the map of the world (with latitude and longitude). Now draw a line that represents about the 40 degree line north of the equator and 40 degree line south of the equator.

Notice how much land mass in the northern hemisphere is above the northern line and how much land mass in the southern hemisphere is below the southern line?

This gives you a good idea why many countries in the northern hemisphere are colder than countries in the southern hemisphere. There are lots of other factors, of course.

The land mass of the world is NOT equally divided or distributed between the north and south.

Weather depends on a lot of factors including things like the geography of the area, ocean currents, and prevailing winds. But something to consider is that there is just a lot more land that is more north than there is south (that people live on).

For example think of Winnipeg, Canada. Pretty cold in the winter, right? Well almost all of the UK is north of Winnipeg which is 49 degrees North. However if we look at land which is 49 degrees South in the southern hemisphere we find… some of Argentina and the Falkland Islands? Auckland Islands of New Zealand are that far south but not much else.

It is? Do you compare land at the same latitude?

Most land in the southern hemisphere is closer to the equator than most land in the southern hemisphere. Look at Target880

It has more to do with the amount of land that’s positioned between the tropics and antarctic. Water acts as a heat sick, so higher percentage of water to land means temps stay more consistent and also the lower amount of land in general mean there are fewer places far enough south to be as cold as places far north are.
