2024 Hennepin County All -Jurisdiction Hazard Mitigation Plan <br />Volume 2 — Hazard Inventory <br />There have been no other incidents that are within the scope of this plan. <br />4.3.8.8. Future Trends Ble <br />In the past few years, there have been several studies published that show to have conflicting conclusions <br />when it comes to trends in past drought occurrence and how the future looks. Part of this is because of <br />the different definitions of drought. Because of the different definitions, a small reduction in the mean of <br />one parameter, can translate into a much larger increase in drought on the other parameters, or <br />definitions. <br />Many of the computer modeling have shown increased trends in drought occurrences across much of the <br />northern hemisphere. However, results of satellite -based studies along with other observation -based <br />studies conclude there is no significant trend in areas with drought in the past three decades. <br />4.3.8.9. Indications and Forecasting <br />Drought intensity categories are based on five key indicators and numerous supplementary indicators. <br />The accompanying drought severity classification table shows the ranges for each indicator for each <br />dryness level. Because the ranges of the various indicators often don't coincide, the final drought category <br />tends to be based on what most of the indicators show. The analysts producing the final determined <br />category also weighs the indices according to how well they perform in various parts of the country and <br />at different times of the year. <br />146 <br />
