High pressure which brings nice weather.
A: Air pressure
A high on a weather map indicates a high pressure area. This indicates a new weather front is moving into that area.
Usually 'H' on a weather map indicates an area of High pressure.
In general high pressure indicates good weather and low pressure indicates storms.
H stands for high such as heat and that is the definition edit by 2797jake: I believe it means a high pressure area and L for a low pressure area. On weather maps the H stands for high-pressure and the L stands for low-pressure.
In general high pressure indicates good weather and low pressure indicates storms.
Increasing air pressure typically indicates that high pressure system is moving into the area. High pressure systems are associated with clear skies, stable weather conditions, and generally calm winds.
A high millibar measurement in a high-pressure area typically indicates stable weather conditions with sinking air, leading to clear skies and sunny weather. High-pressure areas are associated with calm winds and minimal cloud cover.
In a high pressure area, good warm weather will occur. In a low pressure area, colder rainy weather will occur.
Decreasing pressure indicates stormy weather. Increasing Pressure indicates better weather.
