Data: Manitoba Ag-Weather Network Weather Stations

Manitoba Agriculture operates a network of over 100 weather stations across Manitoba's agricultural region which provide hourly updated air temperature, relative humidity, precipitation, wind speed and direction, soil temperature and soil moisture. The WeatherStations feature class displays the location of the weather stations and its table contains a link to current weather for each station. list

Manitoba: 6-month SPI Analysis

Red represents dry, blue for moisture.

Manitoba: Annual NDVI Analysis

This study utilized the MOD13A3 monthly NDVI data at a 1-kilometer resolution and derived the annual NDVI using the MVC method. By examining the images and animations, it's noticeable that Lake Winnipeg, located north of Winnipeg, displayed significant aquatic vegetation in the years 2006, 2009, 2011, and 2022. The reasons for this phenomenon will be investigated further in the future.

Manitoba: April Precipitation Analysis

The data for April precipitation spans a continuous 113 years. There were almost no significant time trends in the first 50 years, but in the last 63 years, from 1961 to 2023, large areas showed a significant trend of reduced precipitation. This was mainly concentrated near Brandon and in the northeastern regions. However, when measuring this trend over the entire 113-year period, its significance is considerably weakened.

Manitoba: March Precipitation Analysis

Based on the three precipitation trend charts, there is a significant decrease in March precipitation, especially in the last 50 years (1975-2023). The most notable annual decrease in precipitation is observed in the northeastern region.

Manitoba: Feburary Precipitation Analysis

Between 1925 and 1974, only a small area in the southwest of Manitoba showed a significant increase in precipitation. However, from 1975 to 2023, there has been a notable decrease in precipitation in large portions of the northeastern and central areas. Throughout the period from 1925 to 2023, there has been a trend of decreasing precipitation near The Pas and in the northern areas of Winnipeg.
