It will take a rainbow coalition to prevent Delhi’s rainy day blues. These successive steps – all low-cost, according to the report – themselves led to a reduction in number of junctions that got flooded. Not only has Delhi’s total rainfall been coming down, the share of heavy rainfall in total rainfall has also come down. Therefore, in addition to monitoring and cleaning of drains, even simple steps such as rejuvenation of water bodies in an area can help in reducing flooding in Delhi.There is a big hurdle in implementing these strategies though – the lack of authenticated data. The problem has persisted despite a fall in Delhi’s total monsoon rainfall as well as heavy rain events. MONSOON – ANALYSIS OF AN APT CAMPAIGN Revision: 1.0 7 | TLP-WHITE | 1 /57 Figure 1 – Word-Cloud of Lure Document Titles “Our MONSOON investigation has uncovered what is clearly a concerted and persistent campaign to steal sensitive data from a variety of critical sources. A third and fourth scenario allowed water bodies and nearby parks to absorb some of the water. Based on these guidelines, issued in 2010, Delhi would need 371 stations. The climate outlook

Introduction .

This is a function of other factors.

Currently, there is not enough information. is based on 30 years of station observations.

So another scenario calculated flood volumes after correcting these flaws. of the 10-day accumulation from the CAMS monthly climatology, which

The team received erroneous data on connectivity, flow directions, dimensions, etc. Since the gridded data set, which has been used for analysing Delhi’s rainfall, provides only 24-hour data averaged over two large areas, it is difficult to know from it either the time for which it rained, or whether it rained more in certain parts of the city.

IMD is in the process of setting up these stations in the next two years, said Mrutyunjay Mohapatra, director general of meteorology at IMD.

As expected, increasing the time frame raises the chances of the intensity of the rain being higher. The 2018 Drainage Master Plan (DMP) report for Delhi prepared by the Indian Institute of Technology, Delhi, for example, could analyse long-term sub-hourly rainfall for only two stations: Palam and Safdarjung. For example, more concretisation in an area would mean less water getting absorbed by the ground despite the same intensity of rainfall. DMP highlighted the massive effort required in collecting digitised data for modeling.

Those questions pertain to the management of the drains,” Gosain said. The report identifies high intensity rainfall events that are likely to repeat in a given time frame. The IIT study accounted for these factors using simulation models to make suggestions for preventing floods in Delhi. Similarly, data on drains in an area provides details of source and volume of run-off and the time this water takes to travel through the drains. An HT analysis of India Meteorological Department’s (IMD) daily rainfall database shows that total rainfall has been declining over the past decade in Delhi. Similar numbers will also have to be generated for more parts in the city. Is it performing its function that it is supposed to perform? It is well-known that the normal position of axis of the monsoon pressure trough extends from Ganganagar, Rajasthan in the north to the head Bay of Bangal in the south. https://www.hindustantimes.com/india-news/not-just-monsoon-poor-data-behind-delhi-s-rain-chaos/story-86xrRb5qaaRP1IkUJVdyBK.htmlNot just monsoon, poor data behind Delhi’s rain chaoshttps://www.hindustantimes.com/delhi-news/rain-likely-in-delhi-over-next-few-days-light-showers-in-ncr-met/story-ByhqaXP5G6x2gzj5gUx1pJ.htmlRain likely in Delhi over next few days, light showers in NCR: Methttps://www.hindustantimes.com/delhi-news/delhiwale-poetry-in-the-time-of-job-loss/story-NKaSuJ7ZUf9iawUJRszmnO.htmlhttps://www.hindustantimes.com/cities/fewer-guests-police-in-ppe-at-red-fort-for-august-15-celebrations/story-NCWIPUhm4nqEBJ7DVL9NaJ.htmlFewer guests, police in PPE at Red Fort for August 15 celebrationshttps://www.hindustantimes.com/delhi-news/dedicated-channel-for-exempted-international-passengers-at-delhi-airport/story-XjQ4wgrxGJ7sLtylpXwVTL.htmlDedicated channel for exempted international passengers at Delhi airportNot just monsoon, poor data behind Delhi’s rain chaos This is worrying because the analysis cannot be a one-time exercise. Key words – Kurtosis, Skewness, Time series analysis, ANOVA. While the deaths were an unfortunate and extreme event, water logging after rains is a common phenomenon in the city. 1. Granular information on rainfall is just one part of the story. the 0- to 5-day and 6- to 10-day accumulations plus the departure Role of stratiform rainfall in modifying the northward propagation of monsoon intra-seasonal oscillation is studied.

Any plan to prevent water logging or flooding will have to take these numbers into account.

Each grid in this database is a box covering 0.25-degree latitude and longitude and Delhi is approximated by two such grids. Two men, one 56 and another 28, drowned in two separate incidents in New Delhi on 19 July.

The climate outlook for precipitation shows

the forecasted change over the next 14 days. Indian Monsoon Data Assimilation and Analysis 2014 – 2017 NCMRWF, IMD, Met Office PI: Dale Barker (MetO) Co-PI: Richard Renshaw (MetO) Purpose: To provide a high-resolution (12km) UM-based 4DVar reanalysis of the Indian region, 1979-now To develop an operational regional NWP system at NCMRWF Run-off refers to the flow of water on the ground when excess rainwater cannot be absorbed by the ground. DMP itself suggests that fresh simulations should be performed after verifying the digital data used with the reality on the ground.“More will is needed on the part of the departments to really join hands and work in an integrated manner.,” Gosain said.

It first calculated flood volumes at junctions in the drainage network as it exists.
