Present Weather codes

The present weather struct based on TMY2 conventions. Note that the most important fields are those representing liquid precipitation - where the surfaces of the building would be wet. EnergyPlus uses “Snow Depth” to determine if snow is on the ground

Fields

thunderstorm: u8

Occurrence of Thunderstorm, Tornado, or Squall

Definition:

• 0 = Thunderstorm-lightning and thunder. Wind gusts less than 25.7 m/s, and hail, if any, less than 1.9 cm diameter
• 1 = Heavy or severe thunderstorm-frequent intense lightning and thunder. Wind gusts greater than 25.7 m/s and hail, if any, 1.9 cm or greater diameter
• 2 = Report of tornado or waterspout
• 4 = Moderate squall-sudden increase of wind speed by at least 8.2 m/s, reaching 11.3 m/s or more and lasting for at least 1 minute
• 6 = Water spout (beginning January 1984)
• 7 = Funnel cloud (beginning January 1984)
• 8 = Tornado (beginning January 1984)
• 9 = None if Observation Indicator element equals 0, or else unknown or missing if Observation Indicator element equals 9

rain: u8

Occurrence of Rain, Rain Showers, or Freezing Rain

Definition:

• 0 = Light rain
• 1 = Moderate rain
• 2 = Heavy rain
• 3 = Light rain showers
• 4 = Moderate rain showers
• 5 = Heavy rain showers
• 6 = Light freezing rain
• 7 = Moderate freezing rain
• 8 = Heavy freezing rain
• 9 = None if Observation Indicator element equals 0, or else unknown or missing if Observation Indicator element equals 9

Notes:

Light

up to 0.25 cm per hour

Heavy

greater than 0.76cm per hour

rain_squalls: u8

Occurrence of Rain Squalls, Drizzle, or Freezing Drizzle

Definition:

• 0 = Light rain squalls
• 1 = Moderate rain squalls
• 3 = Light drizzle
• 4 = Moderate drizzle
• 5 = Heavy drizzle
• 6 = Light freezing drizzle
• 7 = Moderate freezing drizzle
• 8 = Heavy freezing drizzle
• 9 = None if Observation Indicator element equals 0, or else unknown or missing if Observation Indicator element equals 9

Notes:

When drizzle or freezing drizzle occurs with other weather phenomena:

Light

up to 0.025 cm per hour

Moderate

0.025 to 0.051cm per hour

Heavy

greater than 0.051 cm per hour

When drizzle or freezing drizzle occurs alone:

Light

visibility 1 km or greater

Moderate

visibility between 0.5 and 1 km

Heavy

visibility 0.5 km or less

snow: u8

Occurrence of Snow, Snow Pellets, or Ice Crystals

Definition:

• 0 = Light snow
• 1 = Moderate snow
• 2 = Heavy snow
• 3 = Light snow pellets
• 4 = Moderate snow pellets
• 5 = Heavy snow pellets
• 6 = Light ice crystals
• 7 = Moderate ice crystals
• 8 = Heavy ice crystals
• 9 = None if Observation Indicator element equals 0, or else unknown or missing if Observation Indicator element equals 9

Notes:

Beginning in April 1963, any occurrence of ice crystals is recorded as a 7.

snow_showers: u8

Occurrence of Snow Showers, Snow Squalls, or Snow Grains

Definition:

• 0 = Light snow
• 1 = Moderate snow showers
• 2 = Heavy snow showers
• 3 = Light snow squall
• 4 = Moderate snow squall
• 5 = Heavy snow squall
• 6 = Light snow grains
• 7 = Moderate snow grains
• 9 = None if Observation Indicator element equals 0, or else unknown or missing if Observation Indicator element equals 9

sleet: u8

Occurrence of Sleet, Sleet Showers, or Hail

Definition:

• 0 = Light ice pellet showers
• 1 = Moderate ice pellet showers
• 2 = Heavy ice pellet showers
• 4 = Hail
• 9 = None if Observation Indicator element equals 0, or else unknown or missing if Observation Indicator element equals 9=

Notes: Prior to April 1970, ice pellets were coded as sleet. Beginning in April 1970, sleet and small hail were redefined as ice pellets and are coded as 0, 1, or 2.

fog: u8

Occurrence of Fog, Blowing Dust, or Blowing Sand

Definition:

• 0 = Fog
• 1 = Ice fog
• 2 = Ground fog
• 3 = Blowing dust
• 4 = Blowing sand
• 5 = Heavy fog
• 6 = Glaze (beginning 1984)
• 7 = Heavy ice fog (beginning 1984)
• 8 = Heavy ground fog (beginning 1984)
• 9 = None if Observation Indicator element equals 0, or else unknown or missing if Observation Indicator element equals 9

Notes: These values recorded only when visibility is less than 11 km.

smoke: u8

Occurrence of Smoke, Haze, Smoke and Haze, Blowing Snow, Blowing Spray, or Dust

Definition:

• 0 = Smoke
• 1 = Haze
• 2 = Smoke and haze
• 3 = Dust
• 4 = Blowing snow
• 5 = Blowing spray
• 6 = Dust storm (beginning 1984)
• 7 = Volcanic ash
• 9 = None if Observation Indicator element equals 0, or else unknown or missing if Observation Indicator element equals 9

Notes: These values recorded only when visibility is less than 11 km.

ice_pellets: u8

Occurrence of Ice Pellets

Definition:

• 0 = Light ice pellets
• 1 = Moderate ice pellets
• 2 = Heavy ice pellets
• 9 = None if Observation Indicator element equals 0, or else unknown or missing if Observation Indicator element equals 9
