If you have witnessed intense rain in the area you live and not where a relative or friend does, here’s why.

Urban structures – buildings, slums, roads – play a major role in the intensification of rainfall in some pockets across Mumbai, says a study led by Indian Institute of Technology – Bombay (IITB) and funded by the Ministry of Earth Sciences.

Previous studies using satellite data have shown an intensification of rainfall in urban regions. With no uniformity in intense rain across Mumbai, the six-member team studied eight extreme rainfall days during 2014-2015.

Performing eight multi-layer urban canopy model simulations, coupled with atmospheric model that factored in all kinds of buildings, slum areas, and roads for the eight intense rain days, the study found an intensification of rainfall only in some urban pockets that were lined with urban structures.

Researchers said urban structures create atmospheric instability leading to extreme rain that is not uniform across the city. “If there are a series of buildings with a road running in the middle, wind with all its moisture narrows down and follows the path of the road. With buildings acting as obstacles, the wind profile and flow gets disturbed, the atmosphere becomes unstable leading to more rainfall over a specific location,” said Subimal Ghosh, lead investigator and professor with the civil engineering department at IIT-B. “If there were no buildings, winds would have resulted in uniform rainfall over the entire city.”

On comparing their finding with data from automatic weather stations set up by the Brihanmumbai Municipal Corporation (BMC), the results matched confirming that multi-layer urban structures are creating intensification of rainfall over Mumbai.

“There is a need for more weather stations especially in coastal cities like Mumbai, where there is spatial-temporal variation in rainfall pattern. This will help in understanding urban feedback to microclimate and intensification of rainfall, leading to better forecasts,” said Subhankar Karmakar, co-author and professor at the Centre for Environmental Science and Engineering, IITB.

Researchers said the starting point of their investigation was the question that while both laws of physics and satellite data say urbanisation leads to intensification of rainfall, they found no reflection of this signature in spatial data.

In addition to conducting multi-layer urban canopy model simulations, the team also worked with two other scenarios – one that did not consider urban canopy and the other was one-layer urban structure such as roads.

“When we started running the model, we found that compared to non-urban simulations, the single layer urban canopy model was generating slightly more rainfall,” said Ghosh. “But we suddenly found huge intensification of rainfall in the multi-layer urban canopy model.”

The study was published in Scientific Reports – Nature on Friday.

MUMBAI: IIT-Bombay continues to be the top choice for the best of the young brains in the country. The institute has retained its position as the most sought-after IIT in the country, with Delhi and Chennai coming a distant second and third.

A number of factors have been responsible for this, ranging from importance given to streams over geography, from placement records to newer short-term courses on offer, tell students. Of the top 100 rankers in JEE-Advanced 2014, almost all have opted for IIT-B computer science as their first choice. But 58 were allotted seats at IIT-B in computer science in the first round, followed by Delhi, where 36 of the top 100 have been admitted
(see box).

While 58 of the top 100 rankers joined IIT-B, the number has fallen a bit, compared to 67 in 2013. Thirty-six students were allotted seats at IIT-D, as opposed to last year’s 29. IIT-B director Devang Khakhar said he was happy that 44 of the top 50 rankers have opted for the Powai institute. “Students may have placed more importance to the stream over the location and once seats in computer science were filled up, they looked at the other IITs,” he said. IIT-B has 44 seats for computer science and engineering in the open category.

The free online Spoken Tutorials (www.spoken-tutorial.org) of the Indian Institute of Technology, Bombay, is set to take another leap, with the institute offering a spoken guide for advanced computer courses soon.

The online IT literacy project, which was launched in January 2010 with funding from National Mission on Education through Information and Communication Technology of the HRD ministry, will now provide a spoken guide for advanced courses, such as Linux, C and Bash.

Professor Kannan Moudgalya, a faculty member in the chemical engineering department of IIT-B and in-charge of the Spoken Tutorial project, said, “The tutorial is an ever-evolving open source platform through which students in far-flung areas can learn to develop a wide range of software, secure good marks and, eventually, bag jobs in prestigious companies on the strength of training. We are in the process of launching advanced courses.”

The Spoken Tutorial currently has courses in C, C++, Java, Python, MySQL, PHP, Linux and Netbeans. It also has courses in LibreOffice (for office work), SciLab for scientific calculations, GIMP (for graphical design) and Oscad (for electronic circuit design). Over 3.87 students from across India have benefitted from it in the past four years.

The audio-video tutorial aims to bring a revolution in education through technology by teaching programming languages, office tools, graphic and circuit design tools in a simple and interesting manner.

The audio content is available in most Indian languages — Hindi, Kannada, Marathi, Telugu, Assamese, Bengali and even Sanskrit — for which students and teachers from across Mumbai have lent their voices. Soon, all courses will be available in 23 Indian languages.

With the help of the online tool, students can code, compile, execute and test programmes, simultaneously, thus providing a practical complement to theoretical training. The content can be downloaded from the website for free and one can learn on his/her own. Students are allowed to ask questions, which will be answered by experts.
