Why is the hottest month on land in the Northern Hemisphere in July and August in the sea?

Because the specific heat capacity of land is smaller than that of the ocean, the land heats up faster and cools down faster.

The oceans are slower to cool and slower to warm. Thus, when the sun shines directly over the Northern Hemisphere, the hottest temperatures are reached on land a month earlier than over the ocean.

Moreover, there is a process of warming and cooling, and the summer solstice in the northern hemisphere is June 22, which obtains the most solar heat.

The land heats up faster than the ocean, so the highest monthly average temperature on land occurs in the Northern Hemisphere in July, and in the ocean in August.

Specific heat capacity is the amount of heat absorbed by a unit mass of a substance with an increase in temperature1.

A large specific heat capacity indicates that it heats up slowly. Cooling is also slow.

A small specific heat capacity means that it heats up faster. Cooling down is also fast.

In fact, you can understand that in the summer half of the northern hemisphere from March to September, the sun has been supplying heat, and the ocean and land are absorbing heat, but due to the different specific heat, the time to absorb heat until saturation is different, and the land absorbs until July to reach saturation, that is, the temperature is the highest, although it has been absorbing heat but the temperature does not rise. But the oceans need to continue to absorb heat until August, when the temperature does not continue to rise.

Whether in the ocean or on land, the rise or fall in temperature is not a single cause and an immediate reaction.

In addition to absorbing heat from the sun, they are also releasing heat into the atmosphere.

Therefore, even if it is the summer solstice in June, the northern hemisphere receives the most direct sunlight, but the temperature does not rise to the highest point all at once, but continues to absorb heat and continue to heat up; At the same time, the atmosphere is gradually heated by the heat released from the surface, and the temperature difference is getting smaller and smaller, which also prevents the heat release from continuing, so that the maximum point of temperature is reached after a period of delay.

The specific heat of the land is smaller, so it warms up faster, and the specific heat of the sea is larger, so the temperature rises more slowly, so the ocean reaches the temperature peak more slowly than the land.

By the same token, the highest point of the day is not at twelve o'clock in the afternoon, but around two or three in the afternoon; The coldest time is not at twelve o'clock in the middle of the night, but around two or three o'clock in the morning.

The difference between sea and land heat, the specific heat capacity of sea water is larger than that of land, so the temperature rises slowly. That should be the truth

The land is comparable to stones, and the sea is comparable to water, and it heats itself to see.

The specific heat capacity of water is large, and it is not easy to rise and fall temperature.

Summary. During the year, the temperature in the northern hemisphere is the highest in July and the lowest in January on the continent; August is the highest on the ocean and the lowest in February.

This is due to the fact that the specific heat capacity of the land is small, the temperature rises and cools quickly, and the temperature extremes appear earlier. The specific heat capacity of the ocean is large, the temperature rises slowly, the cooling is slow, and the time lag for the occurrence of temperature extremes is delayed.

Why is July the highest on the mainland and August on the ocean?

Hello dear, I am inquiring about the relevant information for you, please be patient, I will reply to you within six minutes, don't worry.

This dress is related to the difference in the nature of the sea and land heating hall. The land heat capacity is small and the temperature increases rapidly, so the highest temperature occurs in July; The heat capacity of the ocean is high and the warming is slow, which occurs in August.

During the year, the temperature in the northern hemisphere is the highest in July and the lowest in January on the continent; August is the highest on the ocean and the lowest in February. This is due to the fact that the specific heat capacity of Lu Roll Sidi is small, the temperature rises quickly, the temperature drops down quickly, and the temperature extremes appear earlier. The specific heat capacity of the ocean is large, the temperature rises slowly, the cooling is slow, and the time lag in the occurrence of temperature extremes is delayed.

Problem description: Why do the highest temperatures in the ocean occur in August, a month later than on land?

Analysis: Because the specific heat capacity of water is large, that is, when absorbing (releasing a certain amount of heat), the temperature rises (decreases) less, resulting in seawater heating and cooling slower than land

When summer arrives, the temperature rises, and the ocean behaves half a beat slower than the land, so the maximum temperature is a month later;

Similarly, in winter, when the earth cools down, the minimum temperature in the oceans is a month later than on land

The highest temperature of the year in the Northern Hemisphere occurs in January.

The distribution of world temperature is observed from the position of sea and land: the sea and land temperatures at the same latitude are not the same, the land temperature is high in summer, and the ocean temperature is high in winter, and the highest monthly average temperature on the continent in the northern hemisphere occurs in July and August in the ocean.

The maximum temperature is the highest temperature in a day, usually at 14-15 o'clock, and the lowest temperature generally occurs around sunrise. Temperature items and units of surface meteorological observation: regular temperature, daily maximum and daily minimum temperature.

Weather stations equipped with thermometers should keep a continuous record of air temperatures. In degrees Celsius ( ), take one decimal place.

Northern Hemisphere Climate:

According to the tilt of the Earth's axis, winter in the Northern Hemisphere begins on the winter solstice (about December 22) and ends on the March equinox (about March 20). Summer begins on the summer solstice (about June 21) and ends on the September equinox (about September 21). The northernmost region of the Northern Hemisphere is the Arctic Circle, and the North Pole is the northern tip of the Arctic Circle.

The seasons can be roughly divided into harsh winters and cold summers, and the temperatures are generally lower than those in other regions. In winter, the North Pole experiences a situation where the sun is below the horizon for one or more consecutive days, called the polar night; In summer, the sun is above the horizon for one or more consecutive days, which is called a polar day.

This can last for at least a day in the Arctic Circle and several months in areas close to extreme. The area south of the Arctic Circle and north of the Tropic of Cancer is the temperate zone of the Northern Hemisphere, and its temperature change is relatively gentle compared with that of the Arctic region, and there are less extreme hot and cold phenomena. However, this mild climate is also prone to difficult weather.

The tropical regions of the Northern Hemisphere (south of the Tropic of Capricorn and north of the equator) tend to have hot weather throughout the year. In general, the summer is the rainy season and the winter is the dry season. In the Northern Hemisphere, large objects passing through or above ground level are affected by the Corylori force and move in the direction of the clock.

Large air currents or ocean currents can also be the case in the Northern Hemisphere, with the North Pacific and North Atlantic currents being the best examples. In the Southern Hemisphere, the direction is reversed.

First of all, this bai

The questions are more general, you know

What does "hottest" mean? Average temperature for the whole month

Inside? The highest average for the whole month.

Capacity? Extreme maximum temperature of the month? Or what?

In addition, the general answer is that although the direct point of the sun shifts after the summer solstice on June 22 in the Northern Hemisphere, the surface temperature is not the same time as the time when the sun directly hits the Tropic of Capricorn, and there are other factors that affect the surface temperature.

At the same time, the earth has seven pressure zones and six wind belts, and under their control, different climate characteristics are formed, and these also directly affect the change of temperature and precipitation. Because the Earth's revolution and the direct point of the sun move seasonally between the Tropic of Capricorn, the pressure belt and wind belt also move. However, it moves slowly, usually about a month behind the direct point of the sun.

So in July and August, the pressure belt moves to the northernmost point, and the temperature in the northern hemisphere is warmer. In April and May, the position of the pressure belt and wind belt is exactly at its initial position, so the temperature will decrease from the equator to the poles, which is what we call spring, and the temperature in the northern hemisphere is not much higher than that in the southern hemisphere.

Another reason why China's temperature is highest in July and August is that Chinese mainland is controlled by the subtropical high pressure ridge at this time, and the temperature is higher.

Because: at this time, the direct point of the sun is near the Tropic of Cancer.

Summary. 1.The main thing is that seawater can play a role in regulating temperature; In summer, the sea temperature is lower than the air temperature, therefore, slowly absorb the heat, release the cold energy, so that the coastal temperature is lower, coupled with the coastal air humidity, precipitation, marine monsoon and other factors, so the temperature is lower than the inland area.

Hello, summer temperatures are a bit cooler in the coastal areas than inland, 1The main thing is that seawater can play a role in regulating temperature; In summer, the sea temperature is lower than the air temperature, therefore, slowly absorb the heat, release the cold energy, so that the coastal temperature is lower, coupled with the coastal air humidity, precipitation, marine monsoon and other factors, so the temperature is lower than the inland area.

2.In inland areas, there is no seawater to regulate the temperature, the air humidity is low, the precipitation is low, and the marine monsoon does not blow, so the summer temperature is higher than that in the coastal areas;

Temperatures on the Northern Hemisphere continent are lower than oceans at the same latitude in January, and temperatures on the Northern Hemisphere continents are higher than oceans at the same latitude in July.

The main reason for this difference is the difference in heat between land and sea. The specific heat capacity of ocean water is large, and the water temperature increases by less and the temperature changes less when it absorbs the same amount of heat. The same amount of capacity is released, and the ocean water temperature decreases with little and the air temperature changes less.

The specific heat capacity of the land is small, and it absorbs the same amount of heat, and the surface temperature increases by a large margin, and the air temperature is high. Releases as much heat as the surface temperature is low and the air temperature is low.

Northern and Southern Hemispheres. Changes in sea and land temperature in January and July.

The seasons in the northern and southern hemispheres are reversed.

Southern Hemisphere. On land, the temperature is generally highest in January (summer) and lowest in July (winter). The sea is a month late, with the highest temperatures in August (summer) and the lowest in February (winter). In January, the land temperature is high and the rent is low, and in July, the sea temperature is high and the land is low.

On land in the Northern Hemisphere, the temperature is generally highest in July (summer) and lowest in January (winter). The ocean is a month late, with the highest temperatures in February (summer) and the lowest in August (winter). In July, the land temperature is high and the sea is low, and in January, the sea temperature is high and the land is low.
