Manitoba Drought Monitoring: Precipitation Conditions App
This app shows short-term (1-month), medium-term (3-month) and long-term (12-month) precipitation conditions for Manitoba.
This app shows precipitation conditions for Manitoba. Precipitation conditions maps are developed to determine the severity of meteorological dryness and are also an indirect measurement of agricultural dryness. Precipitation indicators are calculated at over 40 locations by comparing total precipitation over the time period to long-term (1971 – 2015) medians. Three different time periods are used to represent: (1) short-term conditions (the past one month), (2) medium-term conditions (the past three months), and (3) long-term conditions (the past twelve months). These 1-month, 3-month, and 12-month indicator values are then interpolated across the province to produce the layers in this web map.Long-term and medium-term precipitation indicators provide the most appropriate assessment of dryness as the short term indicator is influenced by significant rainfall events and spatial variability in rainfall, particularly during summer storms. Due to large distances between meteorological stations in northern Manitoba, the interpolated contours in this region are based on limited observations and should be interpreted with caution.Precipitation data is obtained from Environment and Climate Change Canada, Manitoba Agriculture, and Manitoba Sustainable Development's Fire Program.Pop-ups include the following information:Precipitation Indicator NameDate: Precipitation conditions correspond to the specified date.Class: Precipitation class. Precipitation conditions classified as follows:Per cent of median greater than 115 per cent is classified as “above normal”.Per cent of median between 85 per cent and 115 per cent is classified as “normal”.Per cent of median between 60 per cent and 85 per cent is classified as “moderately dry”.Per cent of median between 40 per cent and 60 per cent is classified as “severely dry”.Per cent of median less than 40 per cent is classified as “extremely dry”.For more information, please visit the Manitoba Drought Monitor website.
