Moisture gradient

Calculates moisture gradient.

Usage

hum_moisture_gradient(...)

# Default S3 method
hum_moisture_gradient(hum1, hum2, t1, t2, z1 = 2, z2 = 10, elev, ...)

# S3 method for class 'weather_station'
hum_moisture_gradient(weather_station, ...)

Arguments

...

Additional arguments.

hum1

Relative humidity at lower height in %.

hum2

Relative humidity at upper height in %.

t1

Air temperature at lower height in °C.

t2

Air temperature at upper height in °C.

z1

Lower measurement height in m.

z2

Upper measurement height in m.

elev

Elevation above sea level in m.

weather_station

A weather_station object.

Value

Numeric. Moisture gradient.

Details

The moisture gradient is calculated as the difference in specific humidity at two heights divided by the difference in heights: $$\Delta q / \Delta z$$ where \(\Delta q\) is the difference in specific humidity and \(\Delta z\) is the difference in heights.

Examples

# Calculate moisture gradient
hum_moisture_gradient(hum1 = 80, hum2 = 60, t1 = 20, t2 = 15, z1 = 2, z2 = 10, elev = 100)
