Maritime Day 2021 is on Saturday, May 22, 2021: anymore days like today?
Saturday, May 22, 2021 is Maritime Day 2021.
Each day to recognize the maritime industry, Maritime Day remember the date where the very first American steamship Savannah sail from Savannah in Georgia around the first transoceanic voyage under steam energy.
Different countries have different "days" so it all depends on where you are . Some international days coming up are.
Sept 24 World Maritime Day
Oct 4 World Animal Day
Oct 24 United Nations Day
Dec 10 Human Rights Day
Not very exciting any of them , but if you look at a calendar it should tell you the national days in your country
what is the difference between maritime and continental temperatures?
Typically maritime temperatures see less day-night variations as well as less variations through the year as opposed to continental temperatures which typically have wider swings, both daily and through the year. This is because the water, where maritime air masses exist, has a dampening effect on temperatures, keeping them cooler during the day and warmer at night as opposed to further inland.
How are continental and maritime air masses different from each other?
Continental air masses come from land, maritime come from the sea. cP masses are responsible for those really cold windy days you hear about in the northeast and midwest where the temps go below zero and they call it "arctic air masses". cT are summer only air masses that affect primarily the southwest. They are responsible for those triple digit temperature summer days in Texas, Southern New Mexico, Arizona, Nevada, etc. mP air masses affect the Pacific the most. They drop all kinds of rain in the northwest pacific, but due to strong cP and cT air masses in winter and summer respectively, the mP air is forced away from the southwest, creating desert and arid conditions. mT air affects the southeast the most. That is why it is so hot and humid in the "deep south" during the summer. Maritime air masses usually bring precipitation, and they regulate the temperatures. Look at Alaska. Fairbanks gets disgustingly cold in the winter but Juneau doesn't really get that bad. Fairbanks can get up to 90 degrees some days in the summer, Juneau is lucky to see the low 70s. That is because Fairbanks is dominated by continental arctic (eventual cP) air masses, and Juneau is dominated by mP air masses. In the winter, the whole east sees mostly cP and some mP air masses, except for Florida, the full polar air doesnt usually make it much past Tallahassee/Jacksonville, so thats why Florida is in the 60s and 70s all winter, but the rest of the south gets down in the 30s and 40s some days. Miami, West Palm Beach, Key West are hot in the summer, but are litterally low 90s every day and rarely go past the mid 90s, where as the southwest is always in the 100-120 and rarely goes below 90 in the summer. Again, maritime vs continental. The stable maritime air is very consistent, whereas the unstable continental air is all over the place.
