Question

weather and atmospheric water.

1. what factors need to be included in a thorough weather report?
2. if phoenix, arizona, experiences a cool, wet day in june (when the weather is usually hot and dry), does that mean the regions climate is changing?
3. what happens when a batch of air reaches its dew point? what is the temperature?
4. what effect do clouds have on weather?
5. you are standing in a location that is clear in the morning, but in the afternoon there are thunderstorms. there is no wind during the day, so the thunderstorms build directly above you. describe how this happens.
6. what are the four different cloud groups and how are they classified?
7. how does sleet form? how does glaze form?
8. what circumstances must be present for enormous balls of hail to grow and then fall to the ground?

Explanation:

1. A thorough weather report should include temperature, humidity, wind speed and direction, precipitation type and amount, cloud cover, and atmospheric pressure. These elements give a comprehensive view of current weather conditions.
2. A single cool, wet day in June in Phoenix, Arizona does not necessarily mean the region's climate is changing. Climate is a long - term average of weather conditions, and one anomalous day is not enough to indicate a climate shift.
3. When a batch of air reaches its dew point, water vapor in the air condenses into liquid water (dew, fog, or clouds). The dew - point temperature is the temperature at which this condensation occurs, and it depends on the amount of moisture in the air.
4. Clouds can affect weather in multiple ways. They can block incoming sunlight, cooling the surface (albedo effect), and also trap heat near the surface (greenhouse - like effect). They are also associated with precipitation.
5. In the morning, the air is clear. As the sun heats the ground during the day, the air near the surface warms and rises. If there is enough moisture in the air and an unstable atmosphere, the rising air can cool and condense, forming clouds. Without wind to move the developing clouds, thunderstorms can build directly above the location.
6. The four different cloud groups are cirrus (high - altitude, thin, wispy clouds made of ice crystals), stratus (low - altitude, flat, and often covering large areas), cumulus (puffy, often with a flat base, can grow vertically), and nimbus (associated with precipitation, dark and thick). They are classified based on their altitude, shape, and weather - associated characteristics.
7. Sleet forms when raindrops fall through a layer of cold air and freeze into ice pellets before reaching the ground. Glaze forms when supercooled raindrops hit a cold surface and immediately freeze, creating a smooth, shiny coating of ice.
8. For enormous balls of hail to grow and then fall to the ground, there must be strong updrafts in a thunderstorm that keep ice particles aloft. These ice particles accumulate layers of ice as they are repeatedly lifted and fall through regions of supercooled water droplets. Eventually, the hailstone becomes too heavy for the updrafts to support and falls to the ground.

Answer:

1. Temperature, humidity, wind speed and direction, precipitation type and amount, cloud cover, atmospheric pressure.
2. No.
3. Water vapor condenses; depends on moisture content.
4. Affect sunlight, trap heat, associated with precipitation.
5. Sun heats ground, warm air rises, condenses if enough moisture and unstable atmosphere.
6. Cirrus (high - altitude, thin, ice crystals), stratus (low - altitude, flat), cumulus (puffy, can grow vertically), nimbus (associated with precipitation); classified by altitude, shape, weather characteristics.
7. Raindrops freeze in cold air for sleet; supercooled raindrops freeze on cold surface for glaze.
8. Strong updrafts in thunderstorm, repeated accumulation of ice layers from supercooled water droplets.
