## Visão geral

Interactive weather map visualization showing atmospheric pressure systems, isobars, wind patterns, and weather conditions. Features isobar map with contour lines (4 hPa intervals), high pressure center (H) with sinking air, clear weather, and clockwise wind (Northern Hemisphere), low pressure center (L) with rising air, rain clouds, and counter-clockwise wind (Northern Hemisphere), pressure gradient visualization through isobar density, wind vectors flowing from high to low pressure with Coriolis effect, and weather symbols (sunny ☀️, rainy 🌧️, stormy ⛈️). Animation system for pressure system movement with adjustable speed. Real-time weather map canvas with gradient background (sky blue), colored pressure centers (blue H for high, red L for low), isobar contour lines calculated using pressure field equation, wind vector field with adjustable density and Coriolis effect strength, vertical airflow indicators (downward arrows at high pressure, upward arrows at low pressure), and dynamic weather symbol placement. Current conditions display: high pressure center value (1012-1040 hPa), low pressure center value (980-1000 hPa), pressure gradient (difference), and calculated wind speed in knots. Pressure systems information panels explaining high pressure (anticyclone) and low pressure (cyclone) characteristics. Weather forecast section showing high pressure → clear skies, low pressure → precipitation relationships. Applications: weather forecasting, aviation route planning, maritime navigation safety, and agricultural planning. Interactive controls: high pressure value (1012-1040 hPa), low pressure value (980-1000 hPa), isobar interval (2-8 hPa), wind speed scale (0.5-2.0x), wind vector density (4-16), Coriolis effect strength (0.0-2.0x), animation speed (0.0-3.0x), system separation (0.5-2.0x), and visualization toggles (isobars, wind vectors, weather symbols, vertical airflow, animation). Weather scenario presets: Normal Gradient (1024/996 hPa), Storm System (1020/980 hPa with enhanced winds), High Pressure Ridge (1032/1000 hPa with reduced winds), Low Pressure Trough (1016/988 hPa with strong winds), and Custom. Educational content covering pressure gradient force (PGF = -ΔP/Δn), Coriolis effect (Fc = 2Ωv sin(φ)), geostrophic wind balance, hydrostatic equilibrium, isobar interpretation (spacing indicates gradient strength), high/low pressure system behavior, weather patterns (approaching low pressure deterioration, high pressure fair weather), pressure tendency forecasting, frontal systems, real-world applications (weather forecasting, aviation hazards, maritime operations, agricultural planning, outdoor activities), and historical development (Torricelli's barometer 1643, FitzRoy's weather mapping 19th century, Norwegian cyclone model early 20th century, modern computer modeling). Multi-language support (zh, en, fr, de, es, pt, ru).
