Probability of Heat wave days for cool season crops (>30°C)

Probability of Heat wave days for cool season crops (>30°C) The Probability (likelihood) of heat wave days for cool season crops occurring Heat wave days: The number of days in the forecast period with a maximum temperature above the cardinal maximum temperature, the temperature at which crop growth ceases. This temperature is 30°C for cool season crops (dhw_cool_prob). Week 1 and week 2 forecasted probability is available daily from April 1 to October 31. Week 3 and week 4 forecasted probability is available weekly (Thursday) from April 1 to October 31. Cool season crops require a relatively low temperature condition. Typical examples include wheat, barley, canola, oat, rye, pea, and potato. They normally grow in late spring and summer, and mature between the end of summer and early fall in the southern agricultural areas of Canada. The optimum temperature for such crops is 25°C. Agriculture and Agri-Food Canada (AAFC) and Environment and Climate Change Canada (ECCC) have together developed a suite of extreme agrometeorological indices based on four main categories of weather factors: temperature, precipitation, heat, and wind. The extreme weather indices are intended as short-term prediction tools and generated using ECCC’s medium range forecasts to create a weekly index product on a daily and weekly basis. 2023-02-23 Environment and Climate Change Canada Agri-Geomatics-Agrog@agr.gc.ca Nature and EnvironmentScience and TechnologyExtreme Weather IndicesWeatherWeather forecastsFarmlandsMeteorologyAgricultureClimateTemperature Data Product Specification (French)PDF https://agriculture.canada.ca/atlas/data_donnees/extremeWeatherIndices/supportdocument_documentdesupport/fr/Indices_de_conditions_meteorologiques_extremes_Temperature_SPC_ISO_19131.pdf Data Product Specification (English)PDF https://agriculture.canada.ca/atlas/data_donnees/extremeWeatherIndices/supportdocument_documentdesupport/en/ISO_19131_ExtremeWeatherIndices_Temperature_Data_Product_Specification.pdf Pre-packaged GeoTIF files (No linguistic component)GeoTIF https://agriculture.canada.ca/atlas/data_donnees/extremeWeatherIndices/data_donnees/tif/temperature/dhw/ Pre-packaged Maps (English)PDF https://agriculture.canada.ca/atlas/data_donnees/extremeWeatherIndices/maps_cartes/en/temperature/dhw/ Pre-packaged Maps (French)PDF https://agriculture.canada.ca/atlas/data_donnees/extremeWeatherIndices/maps_cartes/fr/temperature/dhw/
