The announcement comes months after parts of northeast India, including Assam and Meghalaya, were struck by floods, displacing over 4 lakh people, and killing at least 50 people. In total, in 2022 there were over 2,220 deaths related to extreme weather events in the country.

DWR uses this very principle to survey and better predict the weather, thunderstorms, cyclones, and other potential disasters in real-time, as well as forecast changes over a larger area. DWRs are equipped to measure wind speed, temperature, cloud movement, storm activity, and a much wider range of data parameters as opposed to regular weather forecasting systems.

For context, apart from over 4.7 lakh people who were displaced by floods in northeast India, thunderstorms and lightning claimed the highest number of lives in 2022 in India, with 1,285 lives lost, according to the Annual Statement on the Climate of India by the IMD. That's more than half of the 2,220 deaths that extreme weather events caused in India in 2022.

We are now leveraging our big data smarts to deliver on the promise of IoT. By integrating our hyper-local weather data with Smart Home connected devices we are delievering predictive energy efficiency insight to homeowners and Utility companies.

With the improvement in the forecast of extreme weather events, the disaster-related mortalities have been reduced to single digits, Union Minister Jitendra Singh said while addressing the 148th foundation day of the Indian Meteorological Department (IMD). The minister affirmed the relevance of the increased number of doppler radars and also announced that by 2025, the entire country will be covered by the doppler radars.

The number of doppler radars in the country has increased from 15 in 2013 to 37 in 2023 and the minister informed that India will add 25 more radars in the next two to three years which will take the number to around 62. "The entire country will be covered by doppler radars by 2025," he said.

To bolster its weather forecasting capabilities in the Himalayan region, the IMD on Sunday commissioned four doppler radars in Himachal Pradesh, Uttarakhand, and Jammu and Kashmir. The weather department has installed the four doppler radars at Banihal Top in Jammu and Kashmir, Jot and Murari Devi in Himachal Pradesh, and Surkanada Devi in Uttarakhand.

Doppler radar is a specialized tracking system that uses the Doppler effect to track weather conditions and calculate information about the location and velocity of a storm or other forms of extreme weather events. Forecasting with the help of doppler radar is more timely and accurate which can be critical during safe evacuations in the likelihood of extreme weather events.

According to the Annual Statement on Climate of India 2022 issued by the India Meteorological Department (IMD), the country reported the highest number of human casualties due to extreme weather events in three years. The year 2022 saw 2,227 extreme weather-related deaths in India.

Dynamic Frequency Selection (DFS) is a channel allocation scheme specified for wireless LAN, commonly known as Wi-Fi. It is designed to prevent electromagnetic interference by avoiding co-channel operation with systems that predated Wi-Fi, such as military radar, satellite communication, and weather radar, and also to provide on aggregate a near-uniform loading of the spectrum (uniform spreading).[1] It was standardized in 2003 as part of IEEE 802.11h.

When starting operation, an access point automatically selects channels with low interference levels in a phase known as Channel Availability Check (CAC). During this phase, the access point is in a passive state scanning for radar signals. This commonly takes one to two minutes, but could take up to ten minutes. Thereafter, the access point performs In-Service Monitoring (ISM) to detect active radar signals; if radar is detected, and the access point is configured to automatically select a channel, it broadcasts a switch-channel event to its clients and follows by switching the channel. If channels were configured manually, the DFS mechanism causes the access point to go offline.[citation needed]

Prior to the introduction of Wi-Fi, one of the biggest applications of the 5 GHz band was Terminal Doppler Weather Radar.[4][5] The decision to use 5 GHz spectrum for Wi-Fi was finalized in the World Radiocommunication Conference in 2003; however, the meteorological community was not involved in the process.[1][6] Implementation and configuration problems caused significant disruption in weather radar operations in countries around the world. In Hungary, the weather radar system was declared non-operational for more than a month. Due to the severity of interference, South African weather services ended up abandoning C band operation, switching their radar network to S band.[5][7]

The term El Niorefers to the extensive warming of the central and eastern tropical Pacific Ocean which leads to a major shift in weather patterns across the Pacific. This occurs every three to eight years and is associated with a weaker Walker Circulation (see diagram below) and drier conditions in eastern Australia. El Nio Southern Oscillation(ENSO) is the term used to describe the oscillation between the El Nio phase and the La Nia, or opposite, phase.

Generally this means there is less moisture than normal in the atmosphere to the northwest of Australia. This changes the path of weather systems coming from Australia's west, often resulting in less rainfall and higher than normal temperatures over parts of Australia during winter and spring.

In addition to the MJO, other large-scale atmospheric waves also occur in the tropics. The main ones are the convectively-coupled Kelvin wave (KW), equatorial Rossby wave (ER), and mixed Rossby-Gravity wave (MRG). They can provide further insight into the current tropical weather, such as the location and development of tropical cyclones, and what may occur over the coming days to weeks. These waves occur year-round, but typically have a greater influence on tropical weather in the Australian region during the wet-season months of October to April.

Outgoing longwave radiation (OLR) is often used as a way to identify tall, thick, convective rain clouds. These maps show the difference from expected cloudiness based on the position of the MJO. The violet and blue shading indicates higher than normal, active or enhanced tropical weather, while orange shading indicates lower than normal cloud or suppressed conditions.

The Bureau continues to routinely report on the major climate influences on Australia's weather. The influence of drivers such as El Nio and the Indian Ocean Dipole tend to be weaker over the summer months. As has been reported throughout 2023, the model-based long-range forecast of rainfall and temperature provides the best guidance of likely conditions for the months ahead. Long-range forecast guidance will be updated on Thursday 21 December.

Australia's climate has warmed by 1.48 0.23 C since national records began in 1910. There has been an increase in extreme heat and fire weather associated with the warming. There has also been a trend towards a greater proportion of rainfall from high intensity, short duration rainfall events, especially across northern Australia.

These new prediction tools have been utilized since 01 April 2019 for thunderstorm forecast guidance over different parts of India. Currently, IMD issues three hourly thunderstorm nowcast for around 433 stations. IMD is also issuing district level nowcasts for thunderstorm occurrence and related severe weather for all districts of India through whatsapp, SMS, e-mail and IMD website.

The Western Ghats (WGs) located parallel to the west coast of India receives a huge amount of rainfall during the Indian summer monsoon (ISM) where the topography plays a significant role. With a view to understand the dynamics and microphysics of monsoon precipitating clouds over the WGs, a High Altitude Cloud Physics Laboratory (HACPL) has been operational at Mahabaleshwar (17.92 oN, 73.6 oE, ~1.4 km AMSL) since 2012. As a part of this laboratory, a mobile X-band (9.5 GHz) and Ka-band (35.29 GHz) dual-polarization Doppler weather radar system have been installed at Mandhardev (18.04 oN, 73.87 oE, ~1.3 km AMSL, at 26 km radial distance from the HACPL). These experiments gain its importance in this region due to a greater influence of the south-west monsoon and the observations over the radar site can be taken as a representation of the west coast of India. The X-band radar indicates that the dominant cloud movement is from the western side of the WGs to the eastern side, crossing the HACPL and the radar site. The cloud occurrence statistics show a sudden reduction within a distance of ~30 km on the eastern side of WGs which indicates the possibility of a rain shadow area. Further, the vertical structure of cloud over the HACPL has been investigated, and four cloud modes viz., shallow cumulus mode, congestus mode, deep convective mode, and overshooting convection mode have been identified. The frequency distribution of cloud-cell base height (CBH) and cloud-cell top height (CTH) shows that most of the clouds over this region have a base below 2.5 km and tops usually does not exceed 9 km. This indicates the dominance of warm-rain process in the WGs region. The bright band (0oC isotherm level level) has also been detected and it is found to have a top of ~ 5.3 km, bottom ~ 4.8 km with a thickness of 800 m. It is also observed that with increase in 0oC isotherm level and CTH, increase in surface rainfall rates has been observed. The details will be presented in the upcoming symposium.See more of: Air Sea Interaction, Monsoon Predictability, Monsoon Dynamics, Monsoon Variability and Rainfall Distribution
