What are some of the factors that determine the daily fluctuation of air temperature?

What are some of the factors that determine the daily fluctuation of air temperature just above the ground? Some factors that determine the daily fluctuation are due to the earth’s surface, clouds, humidity, large bodies of water, and the idea of urban heat island.

How does temperature vary throughout the day?

An individual’s body temperature typically changes by about 0.5 °C (0.9 °F) between its highest and lowest points each day. Body temperature is sensitive to many hormones, so women have a temperature rhythm that varies with the menstrual cycle, called a circamensal rhythm.

How does earth maintain its temperature?

The earth-atmosphere energy balance is the balance between incoming energy from the Sun and outgoing energy from the Earth. Energy released from the Sun is emitted as shortwave light and ultraviolet energy. In this way, the Earth maintains a stable average temperature and therefore a stable climate.

Why do you think the air temperature is colder on a calm day and warmer on a windy day?

Heat transfer by conduction is the reason it feels colder in the wind. These molecules, because of random motions, will slowly diffuse away from your skin, taking some of your body heat with them. Since diffusion is a slow process you do not lose much heat by conduction on a calm day.

What is the daily condition of the atmosphere?

The day-to-day condition of the atmosphere at a place with respect to temperature, humidity, rainfall, and wind speed is called the weather at that place.

Why do daily temperature ranges decrease as you increase in altitude?

As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands), and the temperature decreases.

How does the temperature change between day and night?

The hotter they are the more they move. The Earth’s surface temperature is controlled mainly by solar heating which turns on at dawn and then off at sunset. Water surface temperature change much less rapidly than land–so land areas are often hotter than the nearby ocean during the day, and cooler during the night.

What does air temperature depend?

Temperature range The size of ground-level atmospheric temperature ranges depends on several factors, such as: The average temperature. The average humidity. The regime of winds (intensity, duration, variation, temperature, etc.)

How does the atmosphere regulate temperature?

The atmosphere also helps to regulate Earth’s temperature. Every day, sunlight (the sun’s radiation) travels through the atmosphere and warms the planet. The atmosphere helps to trap this warmth on Earth – if you remember from the introduction, this process is called the greenhouse effect.

How temperature affects the weather and climate?

Warmer temperatures can also lead to a chain reaction of other changes around the world. That’s because increasing air temperature also affects the oceans, weather patterns, snow and ice, and plants and animals. The warmer it gets, the more severe the impacts on people and the environment will be.

How does the flow of solar energy affect the earth’s temperature?

When the flow of incoming solar energy is balanced by an equal flow of heat to space, Earth is in radiative equilibrium, and global temperature is relatively stable. Anything that increases or decreases the amount of incoming or outgoing energy disturbs Earth’s radiative equilibrium; global temperatures must rise or fall in response.

How is the Earth-atmosphere energy balance achieved?

The Earth-Atmosphere Energy Balance. The earth-atmosphere energy balance is achieved as the energy received from the Sun balances the energy lost by the Earth back into space. In this way, the Earth maintains a stable average temperature and therefore a stable climate. Using 100 units of energy from the sun as a baseline…

How does the time of day affect the intensity of sunlight?

The illustrations show how the time of day (A-E) affects the angle of incoming sunlight (revealed by the length of the shadow) and the light’s intensity. On the equinoxes, the Sun rises at 6:00 a.m. everywhere. The strength of sunlight increases from sunrise until noon, when the Sun is directly overhead along the equator (casting no shadow).

How is energy from the Sun spread evenly over the Earth?

Energy from sunlight is not spread evenly over Earth. One hemisphere is always dark, receiving no solar radiation at all. On the daylight side, only the point directly under the Sun receives full-intensity solar radiation.
