GOES-16 Visible Imagery (Brazil)
With GOES-16 (GOES-East) located at 75 W longitude, the 0-1 hour Convective Initiation product is being demonstrated over Brazil at 15 minute resolution. Above is an example of GOES-16 imagery over Southern Brazil from October 24, 2017 that is used within the Convective Initiation product.
As the NextStorm Convective Initiation product is available anywhere there is GOES data, please contact NextStorm for more information on product use and availability. The Convective Initiation product alerts users to forthcoming heavy rainfall (~20 mm/hour or more), along with other threats brought by convective storms. Users can therefore use this product to anticipate pending threats, especially for people engaged in outdoor activities (e.g., driving, sporting events, boating).
This multi-sensor Lightning Threat algorithm uses a combination of geostationary satellite data and the Multi-Radar/Multi-Sensor System (MRMS) to alert nowcasting forecasters of areas where lightning could occur in the following 45 minutes (derived from satellite data) and where lightning is imminent (MRMS data).
Lightning Threat polygons appear when satellite interest fields of developing cumulus pass a certain threshold. These polygons are displayed in black. If a radar echo of ≥40 dBZ at the –10 °C isotherm, the polygon will turn purple, indicating that a first-flash of lightning is likely. The polygons will disappear once 45 minutes passes. Please note that polygons that occur ≥50-100 miles off the coast are not as reliable as oceanic convection differs significantly from land and near-shore convection.
The Lightning Threat product can be customized for those requiring early detection of lightning, and therefore is valuable for construction, landscaping and other outdoor service companies, as well as for event planning where large numbers of people may find them selves outside when lightning strikes are possible.
