    Hello, and I apologize if this isn't the right place to ask this question. Where I live, Santa Cruz de la Sierra, Bolivia, the map and cross-section often show the asterisk (*) symbol for convective clouds, even though I frequently observe stratus clouds. How do you determine that there are convective clouds and not another type of cloud? For example, today Meteoblue says there are convective clouds, but the reality is that there are stratus clouds.

    [image: 1759153079722-2025-09-29t1300_meteogram_airquality_hd-resized.png] Meteogram Air Quality & Pollen Meteogram Air Quality & Pollen shows a 3-day forecast of air quality and pollen conditions. It visualises: • Common Air Quality Index (CAQI) scale from 1 (good, green) to 100 (bad, red). • Particulate matter: PM10 (particles ≤10 μm) and PM2.5 (particles ≤2.5 μm). • Desert dust concentrations. • Air pollution gases: ozone (O₃), sulphur dioxide (SO₂), and nitrogen dioxide (NO₂). • Pollen forecasts for selected locations (no official colour coding). How it works • CAQI uses the "background" index, not the "roadside" index, since small-scale road effects cannot be resolved by weather models. • PM10 and PM2.5 represent fine particles that can penetrate deep into the lungs; desert dust contributes to elevated values. • Ozone forms in the lower troposphere, especially in urban areas, and impacts respiratory health. • SO₂ and NO₂ mainly originate from burning fossil fuels, reacting to form harmful secondary pollutants. • Time axis uses local time valid when the forecast is created. Limitations • Forecasts are based on atmospheric models at 12 km resolution; local concentrations may differ. • Roadside measurements are typically higher than background forecasts. • Pollen forecasts lack a unified colour coding system. • Not suitable as a replacement for official air quality warnings. Best use cases • Monitoring regional air pollution and pollen exposure risk. • Supporting health-related planning for sensitive groups (e.g. asthma, COPD, allergies). • Tracking pollution trends and seasonal variations. Access Available on the meteoblue website. Extended forecast options via point+ subscription or meteoblue API. Disclaimer Neither the European Commission, ECMWF, nor meteoblue is responsible for use of the forecast information presented here. Always consult your local air quality agency in the case of alerts or high pollution events.

    rainSPOT The rainSPOT is a unique meteoblue visualisation showing regional precipitation around a selected location. It provides a quick overview of how rainfall is distributed in the hours preceding the indicated time. It visualises: • Precipitation totals for the chosen interval (e.g. a 3-hour rainSPOT at 11:00 shows precipitation from 08:00–11:00). • Precipitation intensity with colour-coded shading. • Spatial distribution of rainfall around the chosen location, always centred in the middle grid cell. • Precipitation types (rain, drizzle, hail, ice, snow). How it works • rainSPOT aggregates forecast grid cells: the chosen location is always placed in the central grid cell. • The radius of the outer circle is indicated on the left side of the diagram. • meteoblue models allow global coverage, including mountainous and offshore regions. • Resolution varies by region: – 3–4 km in Europe and North America for the first 3 days. – 12 km for days 4–7, or in other global regions. • rainSPOT works in combination with the pictocast, where additional details such as amount, timing, and probability are shown. Limitations • In mountainous regions, precipitation can be highly localised (e.g. only on a slope or summit), while the grid cell covers a wider area. • A forecast of 1 mm in a 10x10 km cell may represent uniform rain, patchy showers, or even localised heavy downpours. • Radar or satellite adjustments are applied where available, but local variations may still occur. • Forecast accuracy decreases for longer lead times and complex terrains. Best use cases • Identifying whether precipitation will be widespread, showery, or localised. • Tracking thunderstorm activity and precipitation fronts. • Recognising persistent rain events (monsoon, low-pressure systems). • Supporting outdoor planni

  • Discuss medium-range forecasts and how to interpret or apply them.

    What it is The 10-Day Meteogram shows an extended weather forecast for the next two weeks. It combines: • Daily weather symbols • Ranges for maximum, average, and minimum temperatures • Daily precipitation amounts and probability The forecast is based on multiple weather model runs (an “ensemble”) to give a range of possible developments. Weather Symbols • Chosen based on the most likely daily scenario. • In cases of low convergence (models disagree), the symbol may not perfectly match the precipitation data — this is normal. Temperature Diagram • Shows expected maximum and minimum temperatures for each day (local time). • The thick middle line = most probable temperature. • The upper and lower lines = most extreme possible values from different model runs. Precipitation Diagram • Bars (relative to left Y-axis) = daily precipitation amount. • Black lines = possible range between minimum and maximum amounts. • Probability of precipitation (0–100%) is shown below the diagram: o Light blue: 90% o Purple: >95% Note: Probability and pictogram may differ for single events, but they match statistically over many cases. How to Interpret the 10-Day Forecast The 14-day view is most useful for spotting risks of extreme events well in advance, such as frost, heatwaves, or heavy precipitation. Tips: • Convergence (agreement between models) matters: o High convergence = event more likely o Low convergence = event still uncertain • Consistency across weather variables makes an event more probable: o If temperature drop, wind increase, cloud cover, and precipitation all point to the same thing — likely severe weather. o If only one or two variables change — event may be weak or not happen at all. • Check the forecast daily during critical periods to track changes in convergence and probability. Commercial use For business or operational planning, see the meteoblue B2B pages.

    The "More Maps" category provides additional specialised weather visualisations for advanced forecasting, storm tracking, and outdoor activity planning. 1. CAPE & Lifted Index • CAPE = Convective Available Potential Energy (J/kg). Higher values mean more instability and greater potential for severe weather. • Lifted Index (LI) is shown as contour lines on the map. Negative values = unstable atmosphere. • See: CAPE for details. 2. Convective Inhibition (CIN) • Shows the amount of energy (J/kg) needed to lift a parcel of air to the Level of Free Convection. • Higher CIN = less chance of thunderstorms. • See: Convective Inhibition. 3. Lifted Index • Dimensionless value indicating atmospheric stability. • Negative LI = more instability, higher storm potential. • See: Lifted Index. 4. Storm Helicity (0–3 km) • Shows rotation in a storm's updraft, measured in m²/s². • High helicity = greater chance of supercells and tornadoes. • See: Helicity. 5. Solar Radiation • Incoming shortwave solar radiation (W/m²). • Zero during night; lower values often indicate cloud cover. • See: Radiation. 6. UV Index • Measures strength of ultraviolet radiation from the sun. • Colour scale indicates risk level for sun exposure. • See: UV Index. 7. Extreme Forecast • Highlights regions expected to be significantly warmer (red) or colder (blue) than seasonal norms. • Stronger colours = greater deviation from average. 8. Hiking Trail Map • Shows road and trail networks for planning hikes: o White = main roads o Yellow = smaller/forest roads o Red = hiking trails

    Hi everyone, I’m hoping someone here has navigated this specific technical hurdle. I’ve been using the meteoblue All-in-One widgets to track local conditions for a project I'm working on, and they’ve generally been fantastic for accuracy. However, I’ve hit a snag regarding how the widget renders when I'm under a heavy system load. Lately, I've been doing a lot of video editing for some site promotional materials, and I like to include live, high-resolution screen captures of the weather widgets to show real-time changes. The problem is that when my system is processing these high-res video files, the widget seems to struggle to refresh its dynamic layers correctly. Sometimes the wind animation just freezes entirely, or the text becomes incredibly blurry if I try to scale the browser window up for a 4K capture. I’ve checked my hardware acceleration settings and tried both the iframe and the direct script embedding, but the stability just isn't there during these high-demand sessions. Is there a way to force a higher priority for the widget’s script, or perhaps a specific CSS trick to lock the resolution so it doesn't degrade when the system is busy? I’m also noticing that the historical data overlays occasionally desync from the current timeline if the page stays open while the background processes are running. If anyone has tips on maintaining widget crispness during resource-heavy tasks, I’d love to hear your thoughts!
