why the weather is milder when you come closer to the coast of the us?

Question

near coastal areas of the US wether east or west coast have milder and more tolerable weather than the central parts , even few miles makes a difference , what is the scientific explanation for that

Answer 1

the water takes longer to cool down than the land. also the water takes warmer to warm up than the land. the effect is that the coast has warmer winters and when the middle of the country is in the 100s during the summer the coast is in the 80s. the east coast has the gulf stream which is a warm stream in the middle of the ocean it moves from the gulf of mex all the way to russia. this makes the weather warmer and this is also the reason why hurricanes develop stronger in the atlantic, the pacific has the californa stream. this is a cold water stream which goes from the cold waters of the gulf of alaska to the baja coast in mexico. this keeps the west coast much cooler in the summer with temps only in the 70s along most cases, but there winters are in the 60s and 70s which makes it overall warmer than most of the us in the winter

Answer 2

Not only in USA,in any country,coastal stations will have a moderate climate only.The reason is given below.
Most of the coastal stations experience what is called sea breeze and land breeze.The sea breeze,particularly bring moist and cool air either in the afternoon or evening towards the land area and prevents the land from getting heated much than an interior place.
The specific heat of water is more (than that of the soil) and requires more heat for raising its temperature.Moreover, the incident solar radiation is also used to to evaporate a water surface instead of raising its temperature .Apart from this, the heat penetrates to a considerable depth in the case a water surface,whereas, soil, being a poor conductor of heat immediately heats the air above it by conduction thereby making an interior place hotter. So,during day time,the temperature of the sea does not rise much which influences the adjacent land also.
In the case of places which are far away from the coast,the diurnal range of temperature(difference between the maximum temperature and the minimum temperature on a particular day) is more (than that of a sea surface )as land is both a good absorber and radiator of heat than water.
In the night,particularly over the sea surface,the abundance of water vapour exercises a blanketing effect by absorbing the outgoing radiation and re-radiating some of it back to the sea surface thus keeping the sea surface comparatively warmer. This prevents the adjacent land from getting colder in the night.
Thus the sea prevents the adjacent lqnd from getting heated much in the day time and also preventing it get cooled much in the night thereby creating a moderate climate in coastal stations.

Answer 3

That's because oceans store a huge amount of heat and are` slow in releasing heat. Think of the ocean as one big heat "engine"..Also, currents from the south such as the Gulf Stream on the east coast transfer heat along the way. That's why someplace like Bermuda has tropical vegetation despite the fact it isn't that far south-about 560 miles east of North Carolina.

Answer 4

the coast moderates the temperature, making it cooler during the summer and warmer during the winter. however, high winds can occur near the coast making it feel much colder than it actually is. a perfect example of this is boston

Answer 5

the breeze plus the humidity. In city areas these two circle around whereas at the coast it is always fresh, from the ocean, therefore cooler.
