Basic Weather

 

The Basic package is the global standard weather package that you will receive. This tab is located in the layers menu on the map screen and will allow you to turn on and off different layers of different weather systems. These options are:
 

        Current METAR Weather Depiction: Current METAR observations at an airport.

        NWS (National Weather Service) Bulletins. To view the active bulletins for your location.

        EUMetNet Bulletins: Weather and forecast for Europe.

        Infrared Satellite: Giving you cloud coverage split into different worldwide coverage areas.

        Visible satellite: Current visible satellite data available over US and Europe 

        TFRs (Temporary Flight Restrictions):This is for US only.

        Airmets: Airmens Meteorological Information are concise descriptions of actual or predicted weather phenomena localized along an air route and which may have impact on the aircraft safety. This will give you access to icing and turbulence in the US only

        Sigmets:  Significant Meteorological Information are detailed descriptions of actual or predicted weather phenomena which may have impact on the aircraft safety, these reports tend to be more detailed than AIRMET.

        METAR for airports:  This is a routine weather report issued at hourly or half-hourly intervals. It is a description of the meteorological elements observed at an airport at a specific time.

        TAF for airports:  Terminal Aerodrome Forecast is a concise statement of the expected meteorological conditions at an airport during a specified period (usually 24 hours). It uses the same coding as a METAR.

        Current Surface Fronts: Presents images of fronts between how warm, cold dry and moist the air is, fronts will simply mark the boundary between these different types of air. You may see warm, cold, occluded and troughs in this feature.

        PIREPS: Pilot report of actual weather conditions encountered in flight.

Some aerodromes can provide TAFs and METARs,  if this is the case then you might see the dot change color. Clicking on that dot will present you with both the METAR and TAF information. 

The detailed information will present you with the raw text, as well as a more detailed description of the TAF for people who don't understand how to read a TAF.

11  Current Surface Fronts

Let's have a look at the current surface fronts. 

Interaction 1

Interaction 1 Click the Current Surface Fronts slider.

This feature presents you with current surface fonts every 3 hours.
 Cold Front - a zone separating two air masses, of which the cooler, denser mass is advancing and replacing the warmer air.
 Warm Front - a transition zone between a mass of warm air and the cold air it is replacing.
 Trough - an area of relatively low atmospheric pressure. This is the opposite of a ridge.
 Occluded Front - a composite of two fronts, formed as a cold front overtakes a warm front. Two types of occlusions can form, a cold occlusion where the cold air is behind the cold front and a warm occlusion where the coldest air is ahead of the warm front.
 Stationary Front - a front between a warm and cold air mass that is moving very slowly.
