Feature availability and data sources in the Weather app - Apple Support (2024)

FAQs

What are the features of the Apple Weather app? ›

Quickly check current and forecasted conditions by the hour for the next 10 days for temperature, wind, humidity, dew point, feels like temperature, UV index, barometric pressure, and visibility.

Temperature and precipitation map data is provided by Apple Weather. If you use iOS 15.2 or earlier, you might see some temperature and precipitation data that's provided by The Weather Channel. Unless otherwise specified, temperature, precipitation, and wind map data is provided by Apple Weather.

The National Centers for Environmental Information, or NCEI, is the official repository of NWS data and the world's largest archive of an extensive range of weather and climate data.

Weather apps get their information from data providers like IBM, Apple, Foreca, and others. Those providers sometimes do specialized processing to provide more accurate info, or mix in data from personal weather stations, but much of the raw information comes from government agencies like the NOAA.

Weather systems are simply the movement of warm and cold air across the globe. These movements are known as low-pressure systems and high-pressure systems. High-pressure systems are rotating masses of cool, dry air. High-pressure systems keep moisture from rising into the atmosphere and forming clouds.

Weather charts consist of curved lines drawn on a geographical map in such a way as to indicate weather features. These features are best shown by charts of atmospheric pressure, which consist of isobars (lines of equal pressure) drawn around depressions (or lows) and anticyclones (or highs).

Even some of the most well-trusted meteorologists can get it wrong sometimes, but it is interesting to observe how different forecasts are to each other. Many people rely on the weather app on their iPhone, but their predictions can be widely different than that of other weather forecasts.

At The Weather Network, we use the computer model output from many agencies such as Environment and Climate Change Canada. Our meteorologists then select the best of this data and use their own experience to make the final forecast.

Observational data collected by doppler radar, radiosondes, weather satellites, buoys and other instruments are fed into computerized NWS numerical forecast models. The models use equations, along with new and past weather data, to provide forecast guidance to our meteorologists.

Common attributes of this type of data include daily weather summary and the following data points: Average temperature, median temperature, minimum/maximum temperature, expressed in degree Celsius or Fahrenheit. Wind speed in mph or kmph, wind direction. Humidity in hPa, relative humidity in percentage.

What are the sources of the weather? ›

These are temperature, atmospheric pressure, cloud formation, wind, humidity and rain. A small change to any of these conditions can create a different weather pattern. Every weather pattern has a knock-on effect, creating a ripple effect around the world. That's why weather can sometimes seem chaotic.

Sources of information or evidence are often categorized as primary, secondary, or tertiary material. These classifications are based on the originality of the material and the proximity of the source or origin.

Today Weather provides lots of data sources, that help you view accurate weather forecasting wherever you want. Data sources: National Weather Service (weather.gov), Weather.gc.ca, Accuweather.com, Here.com, Dark Sky, Foreca.com, Weatherbit.io, Open Weather Map, Yr.no...

These weather stations measure a large variety of different meteorological parameters, including air temperature; atmospheric pressure; rainfall; wind speed and direction, humidity; cloud height and visibility.

The total with of all the bars are the temperature range for the weeks 10-Day high and low. Each day's colored bar shows its portion of that day within the week.

Open the Weather app on your iPhone. in the bottom-right corner of the screen. Tap the search field at the top of the screen, then enter the name of the city, neighborhood, or location. Tap the location in the search results to display the forecast.

What's more, not all meteorologists use the same models or interpret data the same way, which is why you can see conflicting weather reports from different sources. In iPhone's case, it mostly pulls from The Weather Channel for North America.
