Several functions for calculation of meteorological variables.

Calculations were implemented based on publicly available formulas.

Implemented calculations:

• Dew Point is the temperature at which dew forms.
• Heat Index is an index that combines air temperature and relative humidity in an attempt to determine the human-perceived equivalent temperature.
• Wind Chill is the lowering of body temperature due to the passing-flow of lower-temperature air.
• Feels Like temperature or Apparent temperature is the temperature equivalent perceived by humans, caused by the combined effects of air temperature, relative humidity and wind speed.

Also Temp class is available to convert temperature between Celsius, Fahrenheit and Kelvin. It is also can be mixed with floats for basic math operations.

Requirements

• Python 2.7 or 3.2+

Install

.. code-block:: shell

$ pip install meteocalc

Usage

..note: Any input Temperature value can be provided in different units: Temp(20, 'c') # c - celsius, f - fahrenheit, k - kelvin

.. code-block:: python

from meteocalc import Temp, dew_point, heat_index, wind_chill, feels_like

# create input temperature in different units
t = Temp(20, 'c')  # c - celsius, f - fahrenheit, k - kelvin
t2 = Temp(60, 'f')

# calculate Dew Point
dp = dew_point(temperature=t, humidity=56)

# calculate Heat Index
hi = heat_index(temperature=t2, humidity=42)

print('Dew Point in celsius:', dp.c)
print('Dew Point in fahrenheit:', dp.f)
print('Heat Index in kelvin:', hi.k)

# calculate Wind Chill
wc = wind_chill(temperature=15, wind_speed=25)
print('Wind Chill in fahrenheit:', wc.f)

# calculate Feels Like temperature
fl = feels_like(temperature=40, humidity=40, wind_speed=5)
print('Feels Like in fahrenheit:', fl.f)
