Such forecasts on seasonal time scales can provide an indication of the upcoming months that are either dryer or wetter than normal. We use the information from the <a href=\"https:\/\/climate.copernicus.eu\/\" target=\"_blank\" rel=\"noopener noreferrer\">Copernicus Climate Change Service (CCS)<\/a>. The output of the various CCS models is combined and compared with the 24 year model climatology and 39 years of satellite precipitation data or 30 years of temperature re-analysis data to increase forecast skill. Our data analysis results in categorial monthly rainfall indicators, for example &#8216;increased rainfall&#8217; or &#8216;normal rainfall&#8217;.<\/p>\n<p>Our seasonal forecasts provide the monthly indicators up to 5 months ahead. These indicators can be converted into concrete advices and risk information which is essential for agribusiness, the financial sector and energy sector.<\/p>\n<p><img decoding=\"async\" class=\"alignnone wp-image-4511\" src=\"https:\/\/www.weatherimpact.com\/wp-content\/uploads\/2022\/08\/Telephone_SMS_seasonal_v1-150x300.png\" alt=\"\" width=\"184\" height=\"368\" srcset=\"https:\/\/www.weatherimpact.com\/wp-content\/uploads\/2022\/08\/Telephone_SMS_seasonal_v1-150x300.png 150w, https:\/\/www.weatherimpact.com\/wp-content\/uploads\/2022\/08\/Telephone_SMS_seasonal_v1.png 500w\" sizes=\"(max-width: 184px) 100vw, 184px\" \/><\/p>\n<p>A few examples;<\/p>\n<ul>\n<li>Drought risks for the next season and crop selection support for agronomists<\/li>\n<li>Portfolio risk estimates for outstanding loans<\/li>\n<li>Strategic planning of sustainable energy supply<\/li>\n<\/ul>\n<p>Are you interested in our seasonal forecasting service?

Sub-seasonal forecasts are weekly forecasts up to 6 weeks ahead. These forecasts are at the forefront of the current science and implemented more and more.<\/p>\n<p>Weather Impact has assisted the Bangladesh Meteorological Department (BMD) in the skill assessment and implementation of sub-seasonal forecasts. There, weekly forecasts of temperature and precipitation were implemented up to 4 weeks ahead. The forecasts are used by the Department of Agricultural Extension (DAE) to provide strategic advice to farmers on farm management planning.<\/p>\n<p><img decoding=\"async\" class=\"alignnone wp-image-5579\" src=\"https:\/\/www.weatherimpact.com\/wp-content\/uploads\/2023\/11\/S2S-forecast-20231102-ECMWF-300x154.png\" alt=\"\" width=\"623\" height=\"320\" srcset=\"https:\/\/www.weatherimpact.com\/wp-content\/uploads\/2023\/11\/S2S-forecast-20231102-ECMWF-300x154.png 300w, https:\/\/www.weatherimpact.com\/wp-content\/uploads\/2023\/11\/S2S-forecast-20231102-ECMWF-1024x524.png 1024w, https:\/\/www.weatherimpact.com\/wp-content\/uploads\/2023\/11\/S2S-forecast-20231102-ECMWF-768x393.png 768w, https:\/\/www.weatherimpact.com\/wp-content\/uploads\/2023\/11\/S2S-forecast-20231102-ECMWF.png 1094w\" sizes=\"(max-width: 623px) 100vw, 623px\" \/><\/p>\n<p><em>Fig. 3 Three different forecasts.<br \/>\nThe first deterministic forecast shows the average value of precipitation for a particular week.<br \/>\nThe second anomaly forecast shows the difference between the average value for a particular week with the average climatology of the last 20\/30 years.<br \/>\nThe third probabilistic forecast shows the chance of hotter\/colder temperature or wetter\/drier conditions, compared to the average climatology.<\/em><\/p>\n<p>Are you interested in the assessment and implementation of sub-seasonal forecasts for your region?
