I would assume High and Low. As in, those air pressure diagrams labelled hi and lo. This is just a guess though.
The letter "H" on a weather map indicates the center location of a high-pressure system on US maps. Likewise, "L" marks the center of a low-pressure system.
H means high pressure and L, low pressure.
It means low pressure and low pressure means that wherever the L is there will be stormy weather.
The "L" on a weather map indicates a low-pressure system. Low-pressure systems typically bring cloudy and rainy weather as they are associated with rising air and atmospheric instability.
high pressure is a BLUE H and low pressure is a RED L on the map
h high l low
The letter "H" on a weather map indicates the center location of a high-pressure system on US maps. Likewise, "L" marks the center of a low-pressure system.
On the periodic table of elements, the symbol "H" stands for Hydrogen.
H means high pressure and L, low pressure.
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.
H means high pressure and L, low pressure.
L stans for low such as low heat or low tempiture Usually low pressure.
What does this symbol indicate on a weather map? low pressure
The letter H on a weather map indicates high pressure, while the letter L indicates low pressure. High pressure generally brings fair weather, while low pressure often brings unsettled conditions with clouds and precipitation.
The "L" on a weather map stands for low pressure.
Longitude
High pressure systems are typically represented by a blue "H" on a weather map, indicating an area of descending air that generally leads to clear skies and fair weather. Low pressure systems are denoted by a red "L" on a weather map, indicating an area of rising air that often brings cloudy skies and precipitation.
