- H (High Pressure): Brings cool, dry air and generally clear skies.
- L (Low Pressure): Brings warm, moist air, leading to clouds and precipitation.
2. Weather Fronts
- Cold Fronts (Blue triangles): Cool air replacing warm air, often causing sudden rain showers or thunderstorms.
- Warm Fronts (Red semi-circles): Warm air replacing cool air, bringing gradual, steady rain.
