Temperature - is a physical property that underlies the common notions of hot and cold. Celsius scale is used for most temperature measuring purposes.
Relative humidity - The ratio of the vapor pressure to the saturation vapor pressure with respect to water. This quantity is alternatively defined by the World Meteorological Organization as the ratio of the mixing ratio to the saturation mixing ratio.
Water vapor mixing ratio - Mixing or humidity ratio is expressed as a ratio of water vapour mass per kilogram of dry air, at a given pressure.
Precipitations - is any product of the condensation of atmospheric water vapor that is pulled down by gravity and deposited on the Earth's surface. The main forms of precipitation include rain, snow, ice pellets, and graupel. It occurs when the atmosphere, a large gaseous solution, becomes saturated with water vapour and the water condenses, falling out of solution (i.e., precipitates). Two processes, possibly acting together, can lead to air becoming saturated: cooling the air or adding water vapour to the air.
Wind speed - the movement of air or other gases in an atmosphere. It is a scalar quantity, the magnitude of the vector of motion.
Wind direction - is the direction from which a wind originates. It is usually reported in cardinal directions or in azimuth degrees
