How the forecast is made
The pollen forecast is provided by the Aerostate service, a partner of Yandex.Weather. We then visualize the data received and display it on the map, taking into account the climate and vegetation type of each region. The allergy season and its duration are regularly recalculated depending on temperature, precipitation, and wind direction.
Yandex.Weather forecasts the spread of pollen separately for a short- and long-term period:
- Forecast for the next seven days takes into account the current data on the speed and direction of wind, precipitation, and temperature.
- Forecast for upcoming weeks and months takes into account the climate calendar of the selected area's plant blooming and contains statistics on the spread of pollen over the past seven years of observations.
