North American countries continued to use a Surface Aviation Observation (SAO) for current weather conditions until 1 June 1996, when this report was replaced with an approved variant of the METAR agreed upon in a 1989 Geneva agreement. The WMO's publication No. 782 "Aerodrome Reports and Forecasts" contains the base METAR code as adopted by ...
Cloud-cover symbols used on weather teleprinters and aviation reports in the US [6] In the early 20th century, it was common for weather maps to be hand drawn. The symbols for cloud cover on these maps, like the modern symbols, were drawn inside the circle marking the position of the weather station making the measurements.
The height above the ground or water of the base of the lowest layer of cloud below 6000 meters (20,000 feet) covering more than half the sky. [2] United Kingdom The vertical distance from the elevation of an aerodrome to the lowest part of any cloud visible from the aerodrome which is sufficient to obscure more than half of the sky. [3] United ...
A broken sky has thin strips of clear blue peeking through abundant clouds. Broken clouds don’t form a uniform layer across the sky; they can be thinner in spots and thicker in others.
Continued VFR into IMC is when an aircraft operating under visual flight rules intentionally or unintentionally enters into instrument meteorological conditions.Flying an aircraft without visual reference to the ground can lead to a phenomenon known as spatial disorientation, which can cause the pilot to misperceive the angle, altitude, and speed at which they are traveling.
For a synthetic discussion of the impact of clouds (and in particular the role of cloud bases) on climate systems, see the IPCC Third Assessment Report, in particular chapter 7.2. Cloud base is an important meteorological variable for aviation safety, as it determines whether pilots may use visual flight rules (VFR) or instrument flight rules ...
