The Four Reasons East Coasts Get Colder

Eastern North America and East Asia experience winters far colder than Europe or Western North America at the same latitude. Why is this? Is it due to the Gulf Stream/Kuroshio Current? Or the Rocky Mountains? Are there other factors at play?

I should have added more data to emphasize my point about East Asia providing more stark contrast with Europe than Eastern North America. Comparing average January lows of places at the same latitude: Beijing (-7.1°C) and Philadelphia (-3.3°C), Shanghai (2.1°C) and Brunswick, Georgia (6.7°C), Fuzhou (8.7°C) and Ft. Lauderdale, Florida (16.1°C). The largest difference is in the temperate and subtropical-not boreal-latitudes.

Finally. Every time the difference in temperature between Europe and N.America is brought up on Reddit, so many people will just brainlessly parrot "It'S tHe GuLf StReAm". I try to explain to them that the Gulf Stream's role on Europe's weather is overestimated at best, but it's difficult to go against the hivemind. Now I can redirect them to this video

Things are often more complex than at first glance. It is like explaining global warming to science deniers, and they will instantly cherry-pick if one parameter fits a time-limited scale for their heavy bias. But when it comes to the Gulf Stream it is a tale told for generations, so I understand why it has stuck as a single explanation.

[@StuffandThings_]

What I find even more interesting is that the eastern coasts of continents are also often home to very high latitude tropics, like the Nansei islands south of Japan, Bermuda just east of the American eastern seaboard, Lord Howe island (technically subtropical but like... come on... it has coral reefs) off of eastern Australia and the high latitude almost equatorial climate of Sao Paulo in Brazil. Of course, many of these are islands that don't have the same issues of cold continental air masses and are made warmer by the warm ocean currents flowing along the east sides of continents until the colder currents take over. But then that only makes things even crazier because even staying at the same latitude but changing longitude has some pretty crazy climate shifts. And relatively small changes in latitude have dramatic effect.

Cacti have a pretty unexpected distribution, they grow throughout the Americas, from species in the Amazon to the temperate rainforests of Chile to Brazilian cloud forests to New England to Caribbean islands. So, I wouldn't exactly use that example as a way to show how weird New England's climate is, rather how weird cacti are and how they defy the typical desert stereotype. There are some other rather unexpected plants in the eastern US though, like many tropical looking magnoliids (Magnolia grandiflora and Asimina triloba come to mind) which really highlight the subtropical character of the region.

Most people don't notice it, but if measured at the same latitude the western us (Salt lake city for example) is not really any colder than the eastern us (Cleveland) despite being 4-5 thousand feet higher in elevation. In fact its usually warmer. How is this possible? could you make a video on this. Utah isn't close to the ocean at all so how is it warmer? Do the mountains block the cold?

[@casualearth9076]

1. Essentially, yes. Everything between the Rockies and the Cascades/Sierra Nevadas is protected from the full influence of Continental Polar air masses from the Arctic. Most of the intermountain west is at a high elevation due to the underlying Cordilleran uplift, as you've stated, and it's in a continental position----so it certainly gets cold, but without continental polar air masses, it is still far milder than it would be without being guarded from the north by mountain ranges. You can see this quite dramatically in the few areas of the intermountain west that are at a low elevation. The Snake River plain in Idaho and the Columbia river basin in eastern Washington are in continental positions, but are at a low elevation. Both have areas with a USDA Hardiness zone (average annual extreme minimum temperature) of 7...similar to my hardiness zone much farther south in North Carolina. The Sonoran desert of SE California/SW Arizona is in a continental position, and is in the same USDA Hardiness zone as Southern Florida, despite being at the same latitude as central Alabama. 2. Salt Lake City is a unique case. Despite the high elevation, it's actually in zone 7 as well. Although the Salt Lake is shallow, it has a significant impact on the regional climate--at the same elevation away from the lake, it's zone 6. At dry high elevation areas, winter nights are extremely cold relative to daytime high temperatures. The Salt Lake doesn't have enough depth to balance out seasonal temperature, but it does have enough depth to balance out day/night temperature--it stores the heat of the day and releases it at night. Due to the high salt content, it also will not freeze, so it can have this effect all winter long. It also contributes significant moisture to the Wasatch mountains in the form of lake-effect snowfall.

I think the main reason is the formation of large high pressure zones in winter over the big snow covered landmasses North America and especially Asia that lead to clockwise winds bringing at the east side the very cold air of the high pressure zone south.

[@franklinblunt69]

The gyres need considered beside latitudinal distinctions when Equator to 30 different from 30 to 60, along with influences from seasonal variations beside the coast interface & continent provides wind patterns from differential heating ... Those places mentioned are North of respective Tropic delineations so these climate observations & the influences seem plausible so long as indicate the mechanisms causing them.

[@stewiegriffin3496]

It is quite striking that while east coasts are the colder sides of continents they are at the same time the places that harbour the most polar ward tropical climates in the world such as Florida or the most northerly coral reefs such as in Bermuda. The largest city in Japan's Ryukyu islands which had a borderline tropical climate is a mere 1200 km from places in south Korea with snowy winters at sea level. I assume that is caused by warm currents such as the gulf stream.

[@casualearth9076]

Bermuda and the Ryukyu islands have the distinct advantage of being offshore, so any cold air mass from the continent will be warmed dramatically before it reaches them. It doesn't take a wide fetch for this to happen, either, due to the extremely high heat capacity of water. I'd say Southern Florida's tropical climate is "tropical with an asterisk". Having warm water on three sides helps a lot (and increases the average temp), but it is still vulnerable to cold air mass intrusions. On the eastern sides of oceans/western sides of landmasses, you have the milder winters, but aridity usually prevails in the subtropics. That is likely the main factor keeping tropical species equatorward.

[@stewiegriffin3496]

@@casualearth9076 makes sense. Being mostly surrounded by water is probably the reason why south Florida has a tropical Köppen climate while the Southern tip of Texas isn't. I assume the large southerly expanses of water are also responsible for the poleward tropical climates in South Africa and Brazil.

[@basincityupdatesandbuildtu5394]

I would say Eastern Oregon (south of the columbia Basin) its rarely more than 100-105 most summers due to high altitude. One exception is near Boise/Ontario. You have to go north into the Columbia Basin in Eastern Washington for the 100-110+ degree temps all summer. Eastern and Western Oregon are much closer than you think during summer. The average temp Seattle Vs Tri Cities WA is 79 and 95. Eastern Oregon rarely averages above 88-91 in most of the high desert locations while Portland - Eugene has summer averages 82-86 Though the low altitude desert in Washington doesnt get near as cold in winter as eastern Oregon.

surely this is just a case of latitudes (as well as of other phenomena). For example, at the Equator, the west coast of Africa is warmer than its East coast. I'm sure you cover this in the video, but the title seems to be clickbait. Even the difference between New York and Madrid is not all its cracked up to be - Madrid is 600m above sea level and continental, New York is at sea level and next to the Atlantic Ocean. Comparing New York to Lisbon, and Lisbon is much colder year round. San Francisco is colder than New York. Arica is colder than Rio de Janeiro. In general, the opposite is true because real temperatures on coasts are driven by the seas. What you are referring to is the winter extreme low air temperatures, which may be affected by polar vortices. New York freezes in winter when cold arctic air descends on it, whereas a similar vortex heading for Lisbon has to cross the moist warm Atlantic before hitting it.;

Everyone is going to hate me for this but I think a possible explanation could be considered if we look at the flat earth map theory and their corresponding theory on what the map actually looks like I dont have the map on hand and cant find it on google right now, seems like google deletes anything having to do with those conspiracy theorists, but the flat earth theory map actually shows eastern US and other cold areas to be much closer to antarctica. That map also explains many inconsistencies we see today regarding air flights, such as why when flying from point A to B, its not a direct flight but rather at an extremely wide angle, whereas on the flat earth theory map, it would be a direct line Lastly, another thing to consider, I am from Vladivostok, a very cold city but on same latitude as Spain. The thing to consider is that the number of hours of light during winter gets really short(just as is in any other cold city). This tells me that the cold is probably not due to some kind of current or weather affect, but simply just being closer to the pole than other tropical areas

[@Hostefar]

I don’t know which flat earth map has New York closer to Antarctica (I’m guessing you mean the Arctic), and it causes a lot more flight problems than in solves.

[@artyomarty391]

I am from Vladivostok. Sometimes we refer to that part of Russia as "Far east", sometimes as "Siberia". I think both are interchangeable and correct. Sometimes Far East is referred to be a subsection of all of Siberia, sometimes the two are separate unrelated parts. In school, in Geography and History classes, we almost always referred to ourselves as Far East, not Siberia, although I dont recall anyone ever telling us that we shouldnt call ourselves Siberian Obviously, the winter climate of Vladivostock would be considerably warmer than anything up north, so it is counter intuitive for a comparatively warm city like Vladivostock to be called a part of Siberia, as both Russians and foreigners consider Siberia to be something cold and frosty all year round, while Vladivostock is actually one of the warmer cities in Russia

This makes me curious about how scientists got such accurate data of all of these temperatures across millions of years. Couldn’t it be that we’re comparing temperatures from different regions and geography, thus perhaps using incorrect data?

[@terrybarnes5266]

They don’t have accurate data across millions of years, because that would require the ability to observe air temperatures millions of years in the past. The way climate is modeled in prehistoric times is through the use of various proxies. These proxies are thought to be correlated with the climate in particular region over different epochs of time. Some of these proxies are more reliable than others at determining avg temperatures.

[@artyomarty391]

Its all a theory. Scientists get paid for coming up with grand theories. This is why we constantly see new bold headlines, and forget the ones from last year. Theory after theory. Based on extremely limited evidence. When it comes to meteorology and weather, theories are most grand, because you can never prove or disprove them without going back or forward in time. A meteorologist will tell you he knows exactly what happened to the earth 4 billions of years ago, and how it was created, while struggling to tell you how the pyramids were built just a few thousand years ago. And every few decades the methods for looking into the past get obsolete. For example, a few decades ago Carbon Dating was supposedly a cool thing. Kids were taught about it in school, scientists were discovering a bunch of cool stuff, getting paid, etc, yet now this method is considered to only be theoretical, at best. When it comes to our earth's history, everything is theory, and people who try to convince you otherwise are religious fanatics who dont understand that a true scientist always remains skeptical

[@greasher926]

@@terrybarnes5266 these proxies for example are tree ring width (the wider the warmer the year), ice core ring width (the wider the colder), and if you go millions of years in the past the number serrated edges on a leaf correlates pretty well to avg temperatures, they can also detect CO2 concentrations in gas bubbles trapped in ice cores.

Pretty funny that europe doesn't actually have an east coast lol And asia doesn't have a west coast.

well duh. europe IS the west coast of the Eurasian landmass and asia is the east coast of the Eurasian landmass.
