 Cyclonic Storm Thane named by Burma was the strongest tropical cyclone of 2011 within the North Indian Ocean. Thane initially developed as a tropical disturbance within the monsoon trough to the west of Indonesia. Over the next couple of days the disturbance gradually developed further while moving towards the northwest, and was declared a Depression during December 25, before being declared Cyclonic Storm Thane during the next day. As it was named, Thane started to turn towards the west under the influence of a subtropical ridge of high pressure before its development slowed down during December 27, as a strong outflow and marginally favourable sea surface temperatures fought with persistent vertical wind shear. After its development had slowed down during December 27, Thane became a Very Severe Cyclonic Storm during December 28, before as it approached the Indian states of Tamil Nadu and Andhra Pradesh, it weakened slightly. Thane then made landfall early on December 30, on the north Tamil Nadu coast between Cuddalore and Pondicherry and rapidly weakened into a depression.


This image from EUMETSAT’s METEOSAT-7 satellite over the Indian Ocean shows co-occurring typhoons, Thane in the northern hemisphere on shore in India and Benilde over open ocean in the southern hemisphere. This rare line up of storms shows that storms in the northern hemisphere rotate counter-clockwise, while southern hemisphere storms rotate clockwise. This image was taken by METEOSAT-7 at 0530Z on December 30, 2011.

Brisbane flood, Australia

Brisbane Flood
AAM’s 3D Flood Simulation of Brisbane was used extensively by Australian and Global media during the recent flood crisis in Brisbane. The flood level simulations were produced interactively in 3D. The flood simulation was based on accurate geospatial terrain data created by AAM. AAM provides Engineers and Planners with photo realistic 3D City Models and highly accurate terrain models to aid in their assessment and design tasks.
