Temperature

Temperature, measured in degrees Celsius (°C) or Fahrenheit (°F), represents the warmth or coldness of the air. Warmer temperatures are typically associated with sunny and calm weather, while colder temperatures often accompany cloudy or rainy conditions.

Examples

Here are a few station models with varying pressure and temperature readings:

  • Model 1:Pressure: 1013 mb, Temperature: 20°C – Indicates stable weather conditions with clear skies and moderate temperatures.
  • Model 2:Pressure: 990 mb, Temperature: 12°C – Suggests an approaching weather front with increasing cloud cover and potential precipitation.
  • Model 3:Pressure: 1025 mb, Temperature: 30°C – Represents a high-pressure system with sunny and warm weather conditions.

Wind and Precipitation

Station models provide valuable information about wind and precipitation conditions. Understanding these symbols is crucial for accurate weather analysis.

Wind Symbols

  • Wind Barb:A short line with flags represents wind speed. Each flag equals 5 knots, while each half-flag equals 2.5 knots.
  • Pennant:A longer line with triangular flags represents 50 knots. If there is only one flag, the wind speed is 50 knots; two flags indicate 100 knots, and so on.
  • Calm:A circle indicates calm conditions, with no wind.

Wind Direction

The wind barb points in the direction from which the wind is blowing.

Precipitation Symbols

  • Rain:A solid dot indicates light rain, while a hatched dot represents moderate rain.
  • Snow:A solid triangle indicates light snow, while a hatched triangle represents moderate snow.
  • Freezing Rain:A circle with a dot in the center indicates freezing rain.
  • Drizzle:A series of short, vertical lines indicates drizzle.

Example Station Models

  • Wind:A station model with a wind barb pointing northeast and two flags indicates a wind speed of 15 knots from the northeast.
  • Precipitation:A station model with a hatched dot indicates moderate rain.
  • Both Wind and Precipitation:A station model with a wind barb pointing east and a solid triangle indicates light snow with a wind speed of 10 knots from the east.

Clouds and Visibility

Clouds and visibility are essential elements in station models as they provide information about the sky conditions and how far one can see.

Cloud symbols in station models vary depending on the cloud type and coverage. Common symbols include circles, semicircles, and wedges. The amount of sky covered by clouds is indicated by the number of symbols used, with one symbol representing one-eighth coverage, two symbols representing two-eighths coverage, and so on.

Cloud Cover

  • Clear: No cloud symbols present.
  • Few: One or two cloud symbols, covering less than three-eighths of the sky.
  • Scattered: Three to four cloud symbols, covering three-eighths to five-eighths of the sky.
  • Broken: Five to seven cloud symbols, covering five-eighths to seven-eighths of the sky.
  • Overcast: Eight cloud symbols, covering the entire sky.

Cloud Types

  • Cirrus (Ci): Thin, wispy clouds.
  • Cumulus (Cu): Puffy, cotton-like clouds.
  • Stratus (St): Gray, featureless clouds.
  • Altocumulus (Ac): Small, puffy clouds arranged in rows or waves.
  • Altostratus (As): Gray, sheet-like clouds that often cover the entire sky.
  • Nimbostratus (Ns): Dark, gray clouds that produce rain or snow.
  • Cumulonimbus (Cb): Tall, puffy clouds with a flat anvil-shaped top, often associated with thunderstorms.

Visibility is indicated by a number followed by the unit “SM” (statute miles). It represents the distance that an observer can see clearly. Visibility can be affected by factors such as fog, haze, smoke, or precipitation.

For example, a station model with a cloud symbol of a filled circle and a visibility of 10 SM indicates overcast skies with good visibility.

Additional Information

Station models can also include additional information beyond the basic elements discussed earlier. These additional data can provide valuable insights into the current weather conditions and help forecasters make more accurate predictions.

Dew Point and Humidity

Dew point is the temperature at which the air becomes saturated with water vapor and condensation begins to form. Humidity is a measure of the amount of water vapor in the air. Both dew point and humidity can be indicated on station models using the following symbols:

  • A circle (○): Dew point
  • A slanted line (/): Humidity

For example, a station model with a dew point of 10°C and a humidity of 60% would look like this:

“`┌──────┐│ 10°C ││ / 60% │└──────┘“`
