AIM 8/15/19  1/30/20 (j) Significant clouds. When significant clouds are observed, they are shown in remarks, along with the specified information as shown below: (1) Cumulonimbus (CB), or Cumulonim- bus Mammatus (CBMAM), distance (if known), direction from the station, and direction of movement, if known. If the clouds are beyond 10 miles from the airport, DSNT will indicate distance. EXAMPLE − CB W MOV E “cumulonimbus west moving ....... east” CBMAM DSNT S “cumulonimbus mammatus  .... distant south” (2) Towering Cumulus (TCU), location, (if known), or direction from the station. TCU OHD “towering cumulus overhead” ......... TCU W “towering cumulus west” ............ (3) Altocumulus Castellanus (ACC), Stra- tocumulus Standing Lenticular (SCSL), Altocumulus Standing Lenticular (ACSL), Cirrocu- mulus Standing Lenticular (CCSL) or rotor clouds, describing the clouds (if needed) and the direction from the station. EXAMPLE − EXAMPLE − ACC W “altocumuluscastellanus west” ............. ACSL SW − S “standing lenticular  ......... altocumulus southwest through south” APRNT ROTOR CLD S “apparent rotor cloud south” CCSL OVR MT E “standing lenticular  ..... cirrocumulus over the  mountains east” 10. Temperature/Dew Point. Temperature and dew point are reported in two, two-digit groups in degrees Celsius, separated by a solidus (“/”). Temperatures below zero are prefixed with an “M.” If the temperature is available but the dew point is missing, the temperature is shown followed by a solidus. If the temperature is missing, the group is omitted from the report. EXAMPLE − 15/08  “temperature one five,  .............. dew point 8” 00/M02 “temperature zero, ............ dew point minus 2” M05/ “temperature minus five,  ............... dew point missing” 11. Altimeter. Altimeter settings are reported in a four-digit format in inches of mercury prefixed with an “A” to denote the units of pressure. A2995  −  “Altimeter two niner niner five” EXAMPLE − 12. Remarks. Remarks will be included in all observations, when appropriate. The contraction “RMK” denotes the start of the remarks section of a METAR report. Except for precipitation, phenomena located within 5 statute miles of the point of observation will be reported as at the station. Phenomena between 5 and 10 statute miles will be reported in the vicinity, “VC.” Precipitation not occurring at the point of observation but within 10 statute miles is also reported as in the vicinity, “VC.” Phenomena beyond 10 statute miles will be shown as distant, “DSNT.” Distances are in statute miles except for automated lightning remarks which are in nautical miles. Movement of clouds or weather will be indicated by the direction toward which the phenomena is moving. (a) There are two categories of remarks: (1) Automated, manual, and plain lan- guage. (2) Additive and automated maintenance data. (b) Automated, Manual, and Plain Lan- guage. This group of remarks may be generated from either manual or automated weather reporting stations and generally elaborate on parameters reported in the body of the report. (Plain language remarks are only provided by manual stations). (1) Volcanic eruptions. (2) Tornado, Funnel Cloud, Waterspout. (3) Station Type (AO1 or AO2). (4) PK WND. (5) WSHFT (FROPA). (6) TWR VIS or SFC VIS. (7) VRB VIS. (8) Sector VIS. (9) VIS  @  2$^{nd}$ Site. 7 − 1 − 65 Meteorology
