Heat and Air TemperatureEarth Science Mr. Bimber
What factors affect air Temperature?Insolation (incoming solar radiation) Clouds Water Elevation Ground surface
Insolation: latitude Higher latitudes get the sun’s rays at a low angle, so they’re spread out over a greater area. Near the equator, the sun’s energy is greater.
Insolation: time of dayMorning and evening sun are at a lower angle.
Insolation: time of yearEarth’s axis tilt: the sun’s rays hit at a lower angle in winter than in summer.
Cloud cover: daytime Clouds reflect more of the sun’s rays.
Cloud cover: night Heat rays from earth are reflected back moreon cloudy nights. Clear nights get colder.
Water Water has a high specific heat. It takes more energy,and longer to heat up or cool down than land.
Water nearby Temperature changes much less downwind ofoceans and large lakes.
No water nearby… Temperature changes a lot in dry regions faraway from oceans or large lakes.
Water releases heat when…heat energy is released when water condenses from gas to liquid, or freezes.
Water releases heat when…Air in clouds warms when they rain or snow, so they rise higher because of convection. That’s why these thunderclouds are tall.
Water releases heat when…Night air is warmed when water condenses as dew or frost. It doesn’t usually get much colder than the “dew-point temperature”.
Water absorbs heat when…Air gets cooled when its heat energy is needed to melt ice or evaporate liquid water. (Sweden’s “Ice Hotel” is built every December; still melting in May.)
Elevation The higher you go, the colder it gets.
Ground cover Dark surfaces, like asphalt roads and rooftopsabsorb more heat than light colored surfaces.
Why is this rooftop green?It saves energy and money. Plants help cool the air through evaporation.
Humidity Humidity is the amount of water vapor in the air.Warm air can hold more water vapor than cold air.
Relative humidity Relative humidity is the percent humidity compared to the humidity limit at the current temperature.
Humid air feels warmer. Your body cools itself by evaporating perspiration. When it’s humid, less water evaporates from your skin, so you can’t cool down as well as you can in dry air.
Humidity can affect temperature.When relative humidity goes over 100%, fog, dew, or frost forms. These release heat energy to the air, warming it.
What is “wind chill”? Wind carries your body heat away, and helps water evaporate from your skin, cooling it. The “wind chill” is what the temperature feels like because of the wind.
Temperature factors Factors affecting it:Insolation Clouds Water Elevation Ground cover Factors affecting how cold we feel: Humidity wind
Wind! MCAS Bootcamp:. Wind Caused by the sun. Caused by the sun. Air near the ground is heated. Air near the ground is heated. Warm air is less dense.
The Water Cycle. 75% of Earth’s surface is covered with ocean. 25% of the surface is land (7 continents).
Chapter 5 Lessons 3 & 6 GLOBAL PATTERNS & RELATIVE HUMIDITY.
S6E2.c. relate the tilt of earth to the distribution of sunlight through the year and its effect on climate.
Chapter 2. The Greenhouse Effect The Earth’s atmosphere is compared to the glass walls and roof of a greenhouse –Traps the sun’s warmth for growing plants.
What is Climate? Section 16.1 Pg Climate Is the characteristic weather of a region Includes: temperature, precipitation, air pressure, humidity,
Objectives 1) Identify the factors that cause the intensity of insolation to vary from place to place. 2) Describe how the characteristics of a material.
TEKS 5.8B: Explain how the Sun and the ocean interact in the water cycle. What is the water cycle? The water cycle is the repeated movement of water through.
Air Pressure & Wind Patterns. What is air pressure? Air pressure is the force of molecules pushing on an area. Air pressure pushes in all direction.
Heat Transfer, Albedo, and the Natural Greenhouse Effect.
Humidity and Condensation After completing this section, students will compare the physical characteristics of the three states of water (Standard PI –

The Hydrosphere. The hydrosphere is all of the Earth’s water – both fresh and salt. Water covers about 70% of the surface of the Earth. Of this water.
Humidity and Condensation Water is unique because it is the only substance that commonly exists in all three states of matter. Depending upon temperature,

Fact Statements. Surface currents are mainly caused by prevailing winds. Their flow is controlled by the winds, Earth’s rotation and location of the.
Weather Intro Weather Weather is caused by the unequal heating of the surface of the planet. This occurs in two ways.
Factors that control our weather: the daily weather cycle and the seasons Temps are usually lowest right before sunrise and warmest in the mid- afternoon.

RRB page Factors that control our weather: the daily weather cycle and the seasons Temps are usually lowest right before sunrise and warmest.
Humidity. Remember: Water takes longer to warm and cool because of its high heat capacity. Lots of solar energy is needed to change the state of water!
Air Pressure: The weight of the air in the atmosphere pressing down. At sea level the air pressure is mb (millibars) = 1 atmosphere 1 atmosphere.
