The oceans have a moderating effect on the Earth's climate, helping prevent extremes of air temperature. This is because water takes much longer than air to heat up and cool down. Since about two thirds of the planet's surface is ocean, this has a profound effect on climate. Outside the equatorial regions, this vast body of water tends to store heat during the summer months, and slowly release it during the winter. This is why coastal regions tend to have milder climates than areas that are far inland.
Specific HeatSpecific heat is a measure of how much heat it takes to raise the temperature of a given quantity of a substance by a given amount. This value is more than four times higher for water than for dry air or land. Land heats up quickly, and this heat is easily transferred to the air.
Air over land, however, also cools down relatively quickly. In contrast, much more heat is required to bring about a similar rise in ocean temperature, and so the seas take much longer to heat up. Similarly, they take much longer to cool down. For this reason, in areas that experience seasons, the ocean tends to lag behind the land in terms of temperature.
By Hisham Baig Effects on Climate
This difference in specific heat affects temperature ranges on both seasonal and daily timescales. Days are cooler, and nights warmer, over the oceans than on land. This has an effect on coastal areas, keeping temperatures down during the day, and preventing them from dropping very low at night.
On a micro scale, the effects of ocean temperature can easily be seen at the beach. Usually, air at a beach is a few degrees cooler than the air just a few miles inland during the day. Likewise, during the night, the air at the coast may not cool down quite as much as at inland locations. This is why coastal areas like San Diego have one forecast for the beach, and another for inland areas. The effect can also be seen in wind direction: typically, during the day wind will blow from the sea toward the land, where heat causes the air to rise, and vice-versa at night.
On a longer timescale, in summer, ocean temperature does not reach its maximum until some time after the maximum day length. Similarly, the minimum ocean temperature occurs some time after the shortest day. This influences the climate over land, creating a similar time lag.
As oceans heat up, they release more water vapor into the air, increasing its humidity. This also affects climate, as humid air takes longer to heat up, and retains heat for longer than dry air. Again, this has a moderating influence. Without the oceans, temperatures would fluctuate far more dramatically, probably making conditions impossible for most life forms.
The extent to which the ocean influences climates inland depends on topography. Moist air from a warm ocean can help moderate the climate for a considerable distance, but if it is forced to rise by a mountain range, much of the moisture will condense, forming cloud and producing rain. On the other side of the range, the air will have lost most of its moisture, and the climate will tend to be more extreme.
Ocean CurrentsThe equatorial regions receive more heat from the Sun than the higher latitudes, and this difference in the degree of warming of the oceans leads to currents that circulate heat around the globe. These currents have a huge impact on the climates of some parts of the world. Perhaps the best-known ocean current is the Gulf Stream, which is sometimes known as the North Atlantic Drift. This brings warm water from the Gulf of Mexico northward to northwest Europe, where its effect can be seen by contrasting the winters experienced in this region with those in Eastern Europe. For example, Glasgow in Scotland typically experiences mild, wet winters, while Moscow - at roughly the same latitude - has freezing conditions.
While this may be the most commonly cited example, ocean currents exist all over the world. Some are cold water currents, carrying cooler water from the arctic areas down toward the tropics. These reduce evaporation and humidity, leading to drier conditions with greater temperature variations than is usual for coastal regions. ENSO (El Niño/Southern Oscillation) is a periodic warming of part of the Pacific Ocean off the west coast of South America that has a huge effect on climate all over the planet.

High pressure areas usually cause clear skies and sunny weather. However, low pressure [systems] cause stormy weather, causing precipitation, which may include anything between showers, thunderstorms, or hurricanes. The temperature simply affects the kind of precipitation. Warm temperatures lead to rain, cold temperatures lead to snow, etc.
Low pressure generally brings cloudy or stormy weather. Exactly what you get depends on other conditions such as temperature and humidity. Common weather with low pressure systems can include rain showers, snowstorms, or thunderstorms.
The difference in temperature between a warm tube misfire and a warm tube misfire in hot weather is the temperature that resulted in the hot weather .
it is a 7 million temperature difference
Temperature is a measure of the kinetic energy of the molecules in a substance. Basically how warm or cold it is. Weather is the condition of the atmosphere in a place at any given time. Temperature is a part of this.
Coastal weather tends to be more moderate and influenced by the ocean, resulting in milder temperatures and higher humidity levels. Mountain weather, on the other hand, is characterized by rapid changes in temperature and weather conditions due to elevation, leading to cooler temperatures and increased precipitation, such as snow or rain.
temperature is term used to know how much hot or cold it is......climate is like weather that is hot, cold ..
Because the breath temperature, as it is in the body, it is much more warmer and the room temperature is like the weather that day so it is different.Ria

It is an slandered temperature that has been taken as reference. No system has this temperature some exception are there for perpection systems.
they have the difference or hot or cold weather and the storms they can be bad or not so bad
