Our weather forecast map provides a comprehensive visual representation of current and upcoming weather conditions across a given area. Designed to help you quickly understand complex weather patterns, the map includes the following key elements:
1. Fronts and troughs:
Cold Fronts: Shown as a blue line with triangles pointing in the direction of movement. Cold fronts represent the boundary of a colder air mass advancing into a warmer area, typically resulting in sudden temperature drops, showers, and thunderstorms.
Warm Fronts: Indicated by a red line with semicircles pointing in the direction of movement. Warm fronts signify the leading edge of a warm air mass moving into a region, often bringing gradual temperature increases and overcast skies.
Stationary Fronts: Depicted with alternating red semicircles and blue triangles on opposite sides of the line. These fronts occur when a warm and cold air mass meet but neither is strong enough to move the other, leading to extended periods of cloudiness and precipitation.
Occluded Fronts: Marked by a blue line with alternating blue triangles and semicircles pointing in the direction of movement.. An occluded front forms when a cold front overtakes a warm front, resulting in complex weather patterns that may include varied precipitation and temperature changes.
Troughs: Represented by brown dashed lines extending from a low-pressure area. Troughs are elongated regions of lower pressure that can lead to unsettled weather, including clouds and precipitation.
2. Lows and Highs (Pressure Systems):
Lows: Indicated by a large "L" on the map. Low-pressure systems are associated with rising air, which can lead to stormy and rainy conditions as air converges and lifts.
Highs: Shown with a large "H" on the map. High-pressure systems are characterized by descending air that generally leads to clear, stable weather with little precipitation.
3. Major Weather Events:
