What does ULI mean in Meteorology?

Uli

Uri is the name given to the traditional designs drawn by the Igbo people of Nigeria. Uri drawings are strongly linear and do not have deep perspective; they do, however, balance positive and negative space. Designs are frequently asymmetrical, and are often painted spontaneously. Uri generally is not sacred, apart from those images painted on the walls of shrines and created in conjunction with some community rituals. The drawing of uri was once practiced throughout most of Igboland, although by 1970 it had lost much of its popularity, and was being kept alive by a handful of contemporary artists. It was usually practiced by women, who would decorate each other's bodies with dark dyes to prepare for village events, such as marriage, title taking, and funerals; designs would sometimes be produced for the most important market days as well. Designs would last about a week. Most uri designs were named, and many differed among various Igbo regions. Some were abstract, using patterns such as zigzags and concentric circles, while others stood for household objects like stools and pots.
