Wildfires propagate by sending sparks downwind, igniting the dry material and spreading the fire. A new study published in Nature Geoscience looks at the propagation of droughts and shows that droughts move by creating rainfall deficits that cause areas of dry soil downwind. That eventually expands the drought as rainfall is suppressed by the lack…

The latest Drought Monitor, released today, shows that there have been slight expansions of drought in North Carolina, Florida, and Georgia this week due to lack of rainfall, while the other states did not change. Puerto Rico saw a slight decrease in dry conditions this week. Rainfall amounts the next few days should be relatively…

I’ve gotten some emails lately asking about how to report dry conditions and drought so that the Drought Monitor authors recognize that things are getting crunchy here in parts of the Southeast. Here is a refresher on what sites you can use to do it: There are a lot of different tools for monitoring drought…

Droughts come and go as a natural part of climate. Some species of plants and animals are adapted to drought and need it as part of their life cycle. However, prolonged drought can cause devastation to the areas that are affected by it, and the people that live there can suffer significant hardship due to…

The latest Drought Monitor, released today, shows only slight changes in most of the region from last week’s map. The biggest change was in Alabama, where recent rains have eliminated the small area of drought and substantially reduced the area of abnormally dry (D0) conditions. Other states had small changes to the areas of abnormally…

How does dust affect climate across the world? While we don’t think about it too often here in the Southeast, it is a big issue in other parts of the country and the world. Dust can affect the transmission of sunlight to the surface, coat the surfaces of glaciers (which affects how they melt), and…

I ran across a very interesting (new to me) blog this week on soil with an article on soil moisture and its importance to agriculture. The University of Georgia weather network cooperates with the group described in the article; that group collects soil moisture from agricultural weather networks across the US because it is critical…
