Convective Initiation (CI)<\/h1>\n

Demonstrational product by NWC SAF.<\/p>\n

\n

Application:<\/h2>\n

CI provides an estimation of the probability for a low cloud to develop as a thunderstorm in the next 0-30\u2019, 0-60\u2019 or 0-90\u2019 interval.<\/p>\n

The product aims to catch the first steps of initiation of convection, when the first convective signs occur after the formation of clouds, or when those signs appear revealing a modification of environmental conditions.<\/p>\n

Advantages:<\/p>\n

\u2713 Available over the geostationary satellite coverage.<\/span><\/p>\n

\u2713 Useful for early warning systems and forecasting.<\/span><\/p>\n

Limitations:<\/h2>\n

X No detection In cases of cirrus above low clouds.<\/span><\/p>\n

X High False Alarm Rate inherent to CI.<\/span><\/p>\n

X Lack of validation.<\/span><\/p>\n<\/div><\/div>\n
