A better understanding of the ground beneath our feet may be the key to improved seasonal weather forecasts, say an international team of environmental scientists in the journal Science today.
Researchers investigating the impact of soil moisture on rainfall have found that, across the globe, there are at least three hotspots where rainfall seems to be directly influenced by the amount of moisture in the soil, leading to the tantalising possibility of more accurate long-term weather forecasts.
Dr Christopher Taylor, from the Natural Environment Research Council‘s Centre for Ecology and Hydrology said: “We modelled soil moisture around the world and compared it with modelled rainfall. We found that in very wet or very dry areas the impact of changes in soil moisture on rainfall was negligible. But in the areas in between it was a different story. Here it seems, moisture and rainfall are connected.”

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.
When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
