Drizzle appears to float while following air currents, although unlike fog droplets, it falls to the ground.
Drizzle: Fairly uniform precipitation composed exclusively of fine drops with diameters of less than 0.02 inch (0.5 mm) very close together. Precipitation is any of the forms of water particles, whether liquid or solid, that falls from the atmosphere and reaches the ground. Under these circumstances “FG” rather than “FZFG” is to be reported since airlines tend to experience operational penalties whenever FZFG is reported. In cases where visibility is less than 1 000 m and the temperature is below minus 30o C it is unlikely that suspended super cooled water droplets are present (unless there are sources of open water nearby). different types of precipitation occurring at the time of observation are to be reported as one single group with the dominant type of precipitation reported first, preceded by only one intensity qualifier which refers to the intensity of the total precipitation, in the form “+TSRASN” and “–SNRA FG”. where two different types of weather are observed, they are to be reported in two separate groups, in the form “+DZ FG” or “–DZ VCFG” where the intensity or proximity indicator refers to the weather phenomenon which follows the indicator and. this is followed by both the characteristics and the type of weather phenomena in the form “+TSRA” or “VCFG”. an indication of intensity or proximity (METAR only), as appropriate, is to be reported first.

This ICAO code is Paris-Orly airport / LFPO. 3rd and 4th letters determine an airfield. 2nd letter determines a country in the world area ( F for France). 1st letter determines an area in the world (France is in the L area). Nearly all airports in the world have a unique ICAO code it is a location indicator with 4 letters. The location indicator is the ICAO four-letter location indicator for the aerodrome for which the report is made. Now, we will start decoding the following METAR: The inch of mercury (inHg) for the atmospheric pressure in America (1013hPa=29,92 inHg). 
The American land mile 'SM' for the visibility in North America. The kilometer per hour 'km' (km/h) in Russia for the indicated airspeed. The meter per second 'mps' (m/s) in Russia for the wind speed. Some unities can change depending of the countries. The degree Celsius (☌) for the temperature measurement. The hectopascal (hPa) for the atmospheric pressure (QNH QFE). 
The meter (m) for the horizontal visibility.

The knot (kt) for the wind speed (kt=nautical mile per hour).The feet (ft) for the clouds height above ground.The unities are also variables and have been settled from the history development of aviation and the influence of USA and British pioneers in aerospace.

MET REPORT YUDO 221630Z WIND 240/5MPS VIS 600M RVR RWY M MOD DZ FG CLD SCT 300M OVC 600M T17 DPHPA These codes and local reports use the approved ICAO abbreviations contained in the Procedures for Air Navigation Services. The METAR and SPECI code forms were developed by the World Meteorological Organization on the basis of aeronautical requirements established by ICAO.
Local routine and special reports, and METAR and SPECI from fully automatic systems can be used without human intervention (Automated METAR). The specific types of observations and related reports are disseminated either locally, or to other aerodromes. The actual weather observations at aerodromes and offshore structures are made by aeronautical meteorological stations. Meteorological service for international aviation is provided by meteorological authorities designated by States.
12.3 Intensity/proximity of present weather phenomena. 12.2 Characteristics of present weather phenomena. 12.1 Types of present weather phenomena. 9 Significant speed and directional variations. 7 Identification of an automated or a missing report.
