PPT-Clouds, Rain and Moisture

5 Water in the atmosphere in all its phases Last week we focussed on the weather systems found in the midlatitudes The heart of the midlatitudes is the polar front where warm tropical air from the south meets cold polar air from the north. Water is ALWAYS in the atmosphere!. Earth’s water is mostly found in the oceans, but it is also found in lakes, rivers, ice sheets, in plants, and underground.. It can be present as a solid (like snow), liquid (rain), or gas (water vapor). . rainrate. increases. Kubar. , T., D. L. Hartmann, and R.

Rain notes for Teacher. “Rain . makes the grass green . and your . garden grow. . When the air holds lots of water droplets, clouds form. If a lot of water droplets gather in the clouds, the clouds become heavy. Gravity causes the water droplets to fall as rain. . Notes/Vocabulary. How do clouds form?. when warm air & cold air meet, cold air pushes up the warm air and a cloud can form. when air rises and cools, the water vapor in the air condenses into tiny water droplets and forms a cloud. Precipitation. We’ve studied the water cycle, and last week we focused on the “Condensation”. part. Now, we are going to discuss the precipitation part of the water cycle.. Let’s watch this video on Precipitation!. and . Sky Conditions. S4E3. Students will differentiate between the states of water and how they relate to the water cycle and weather.. e. Investigate different forms of precipitation and sky conditions (rain, snow, sleet, hail, clouds, and fog).. Water is ALWAYS in the atmosphere!. Earth’s water is mostly found in the oceans, but it is also found in lakes, rivers, ice sheets, in plants, and underground.. It can be present as a solid (like snow), liquid (rain), or gas (water vapor). . Jassem. al . Majed. abdulAziz. al . hashash. Fawaz. al . enezi. Abdullah . bahzad. vocabulary. Evaporation. Condensation. Precipitation. Humidity. Saturation. Relative humidity. Dew point. Cirrus. How is rain made?. The sun has been warming the ground all morning.. The ground warms the air and the temperature rises. The warm air rises.. As the warm air rises, it cools and the water vapour (tiny droplets of water) in the air condenses to form clouds.. Rate of Respiration Loss Depends on Internal Crop Moisture and Air Temperature. 80 70 60 50 40 30 20. Moisture level, %. 0.40. 0.35. 0.30. 0.25. 0.20. 0.15. Cirrus clouds can best be described as “ice-crystal” clouds that look like wispy curls of hair. These clouds are often the first signs of approaching weather changes. . Cirrus. These clouds are often referred to as “mackerel sky”. The ripples in these clouds look like the scales on a fish and are a sign of unsettled weather to come. . Clouds. Precipitation . Weather is affected by the amount of water in the air.. . Don’t forget. transpiration.. Humidity. the amount of water vapor (moisture) in the air. warm. air can hold more moisture. WeatherDew-When the dew is on the grass Rain will never come to pass When grass is dry at morning light Look for rain before the nightAgain if there is no dew on the grass it meansthe sky is cloudy or Basic .
