Study Notes
Weather and Meteorology
- Weather refers to the current atmospheric conditions.
- Meteorology is the scientific study of the atmosphere, enabling weather predictions.
Temperature Scales
- Celsius and Fahrenheit scales reference points: freezing and boiling.
Wind Directions
- An east wind blows toward the west.
- A weather vane pointing at 225° indicates a southwest wind.
- Regional winds at 20°S typically blow northwest.
Humidity
- If absolute humidity is 15g/m³ and the air can hold 25g/m³, relative humidity is approximately 60%.
Wind Factors and Effects
- The primary factor in the formation of regional winds is atmospheric pressure.
- Winds deflect over long distances due to the Coriolis effect.
- High-altitude winds are less influenced by friction compared to surface winds.
Seaside Wind Patterns
- Winds tend to be calm at seashores during dawn or dusk.
Cloud Formation
- For clouds to form, air must reach or drop below the dew point.
- Air masses cool upward due to particle movement resulting in heat loss.
Weather Hazards
- Supercooled water can lead to dangerous conditions, such as aircraft crashes or icy roads.
Cloud Characteristics
- Fluffy high-level clouds are classified as cirrocumulus.
- The term "altocirrus" is incorrect because cirrus are high-altitude clouds, while alto- refers to mid-level clouds.
Cloud Droplets and Raindrops
- A typical cloud droplet measures about 0.02mm, while an average raindrop is around 5mm.
Precipitation Types
- Freezing rain falls as liquid and instantly solidifies upon contact with surfaces.
- Sleet falls in solid form.
Hail Formation
- Hailstones develop through supercooled water being lifted by updrafts, coalescing until they are heavy enough to fall.
Frost Formation
- Frost forms when both the dew point and air temperature are below freezing.
Weather Control Perspectives
- Controlling the weather is seen as beyond human capability; predictions are possible, but ultimate control is thought to belong to a divine power according to some beliefs.
