Why are there different temperatures in places that are on the same latitude on the globe?

an example is minneapolis and seatle.

    The factors affecting the temperature of a place are(1) latitude(2) Altitude(3) Land and sea distribution(4) Prevailing winds(5)Slope of the ground(6) Nature of the soil and (7)presence of snow or ice covering.

    Altitude:-As the temperature decreases with height,altitude is a dominating factor determining the temperature of a place.

    Land and sea distribution:-An interior place is subjected to extreme of heat and cold while the land area adjacent to sea and oceans enjoy more equable conditions.This is due to the following reasons.

    The specific heat of water is more than that of a soil and hence water requires more heat to raise its temperature.The incident solar radiation is mainly utilised to evaporate the water from the surface only and not to raise its temperature.Moreover the heat from the incident solar radiation penetrates to a considerable depth in the case of water.These are the reasons for a coastal station like Seatle to experience a moderate climate.

    Prevailing winds:-Moving air normally carries the temperature of the place of origin, is getting modified by enroute weather and is arriving at a place as warm or cold current.

    Slope of the ground:-If the ground is appreciably steep, there is every chance of forming cold katabatic winds at night and warm anabatic winds during day time.

    Nature of soil:-Bare soil and sandy soil are good absorbers and good radiators of heat resulting in extremes of temperatures on the surface during day and night.

    Presence of snow and ice covering:-Snow is a good reflector heat and fairly good radiator of long-wave radiations.Consequently,the temperature over a snow surface tends to sink to very low levels.Not only this,the incident solar radiation will melt the ice only and not raise its temperature above the freezing point.So extremely low temperatures are therefore experienced in places where there are snow or ice covering .The poles are good examples.

    Hence even if two places are on the same latitude, different temperatures are met due to the above reasons.

    They have two completely different climates.

    In Minneapolis they have cool winters and hot summers because they are inland and they don't get an offshore or onshore flow of wind. This is the same for all inland areas.

    In Seattle they have very little change in temperatures over the course of the year. They have cool summers and warm winters. This is due to a cool ocean current moving southward along the Pacific Coast while there's also a warm ocean current moving northward along the Pacific Coast parallel to the cool ocean current. They also get sea breezes (onshore flow of wind) and land breezes (offshore flow of wind). In Seattle during the summertime the air temperature is prevented from getting warmer than the ocean temperature. So there's a difference in air pressure so it creates a sea breeze. During the wintertime the air temperature is prevented from getting cooler than the ocean temperature. So when there's a difference in air pressure it creates a land breeze and that prevents the air temperature from getting cold in the winter. This is the same for all coastal areas.

    Big difference huh?

    The most important feature is ocean currents. The Gulf Stream carries a huge amount of heat toward Britain and Ireland, and as a result Scotland has a climate similar to that of Seattle, hundreds of miles farther south. Other physiographic features also have effect; Minneapolis is isolated from the moderating effects of the ocean (experienced by Seattle) by a thousand miles of mountains.

    Trade winds, gulf stream air masses, artic express, etc. Next time you watch the weather note the curving arrows...it has to do with wind flow patterns....
