Severe Storm
Definition
Storms are generally classified as a meteorological hazard, caused by short-lived, micro- to meso-scale extreme weather and atmospheric conditions that last from minutes to days (EM-DAT).

On 1 April 1960, NASA sent the Television Infrared Observation Satellite (TIROS-1) into space. TIROS-1 was developed during the 1950s and, after years of experimental programmes and attempts, became the world’s first weather satellite. Since weather satellites were a new technology at that time, the mission also tested various design issues for spacecraft, such as instruments, data, and operational parameters, in order to improve satellite applications for Earth-bound decisions. TIROS-1 thus paved the way for further weather satellite development and research. Today, weather satellites provide highly accurate and near-real-time measurements that can efficiently monitor and forecast extreme weather events, such as floods and droughts, as well as enhance the understanding of the climate and of the Earth as a whole.
TIROS-1 provided information about cloud formations around the globe. It orbited 450 miles above Earth and communicated with two command and... read more

The Japan Aerospace Exploration Agency (JAXA) has released the JAXA Climate Rainfall Watch website to monitor extreme weather and climate over the world. The website provides hourly global measurements of precipitation as well as forecasts about heavy rainfall and drought in different temporal scales (daily, pentad, weekly, 10-days and monthly). The satellite-based global rainfall maps produce highly accurate measurements that can help better understand the changing climate, improve forecasts of extreme weather events, such as floods and droughts, minimize their damage and strengthen early warning systems.
The Climate Rainfall Watch website monitors heavy rainfall and drought in near-real-time and collects and stores data from previous months. The website calculates rainfall in percentile: heavy rain is indicated by large percentile value and displayed in dark pink color. The website also monitors drought using the Standardized Precipitation Index (SPI),... read more

Upon the request of the Ministry of Territorial Administration (MINAT), Government of Cameroon, UN-SPIDER carried out a week-long Institutional Strengthening Mission (ISM) to Yaoundé from 15 to 19 July. The mission aimed to strengthen the capacities of the Department of Civil Protection (DPC) of Cameroon in using space-based information in all phases of the disaster management cycle. It was the third UN-SPIDER mission to Cameroon after a Technical Advisory Mission (TAM) in 2011 and an Institutional Strengthening Mission (ISM) in 2012, the latter including a training course on “Remote Sensing for Disaster Management”.
During the mission, UN-SPIDER experts and an expert from its Nigeria Regional Support... read more

According to a new study by scientists from NASA and NOAA, tropical cyclones stall more frequently and stay longer near the coastline. This potentially leads to more precipitation over confined locations and thus an aggravation of tropical cyclone hazards for coastal populations.
In the new study, scientists Hall and Kossin examined all tropical cyclones from 1944-2017 in the National Hurricane Center's HURDAT2 database to analyze the position and calculate the average forward speed of each storm that has reached the coastal regions and to investigate the direction of the storm track. They found that 66 storms in the North Atlantic stayed in a coastal region for more than two days. Almost half of these 66 stalls appeared in the last third of the 74 years they analyzed, while only 17 appeared in the first third. In addition, they found that long-lasting storms were more likely to contain meanders.
The trajectory of a tropical cyclone... read more

A recent study, published in the Water Resource Research journal, presents a new method for a spatially realistic national flood risk assessment.
Researchers expanded an existing statistical model, based on U.S. Geological Survey (USGS) river flow data, to simulate a thousand years of potential flood events. By calculating the damage for each event in dollars, they were able to estimate the probability of the United States suffering particular annual flood damages.
Traditional risk flood analysis models assume that the impacts on the entire flood-affected area are the same, but flooding can be more severe in some areas than in others, even during the same flood event. At national scales, traditional risk analyses can only estimate the average annual loss. To estimate the total annual losses that might occur in more extreme flooding... read more

In the past year, “there were 315 natural disaster events recorded with 11,804 deaths, over 68 million people affected, and US$131.7 billion in economic losses around the world.” This is according to the Centre for Research on the Epidemiology of Disasters (CRED) in its recently released 2018 Natural Disasters Report.
While these 2018 natural disaster values represent a decrease when compared with the annual averages from 2008 to 2017, some geographic areas still experienced great losses of life and damages due to natural hazards. Indonesia was most adversely impacted in terms of lives claimed, with earthquakes in August and September 2018 that left a total of 4,904 people dead or missing, according to the CRED. Earthquakes also accounted for the greatest number of deaths among natural disasters worldwide in 2018. And among all types of natural hazards, floods affected the greatest number of people during the past... read more

During this webinar, you will learn how to process and visualize Sentinel-1 data to look at a hurricane and the damage it inflicts using SNAP toolbox.
Studies show that typhoons, hurricanes and other extreme weather events have become more frequent as a result of ongoing climatic change and this trend is likely to continue. These extreme weather events carry substantial human and economic costs. A publication by the (EASAC) reports that economic losses due to thunderstorms in North America have doubled between 1980 and 2015.
Using remote sensing we can monitor the storms themselves and the damage they cause (for example identify the most severely damaged areas). In this exercise we will have look on how to use the three Sentinel-1 data products (SLC, GRD and OCN) to see different aspects of the typhoon Habibis and its effect.
The Asia-Pacific region faces major disaster risks in the form of earthquakes and tsunamis, tropical cyclones and typhoons, landslides, flash floods, avalanches and glacial lake outburst floods (GLOFs). Due to the large spatial extent of disasters affecting several people across countries, geospatial technology today finds a wider acceptance and an important tool for decision making process. As disaster management work usually involves a large number of different agencies working in different areas, the need for utilizing geo-information technologies in multiple disciplines to make critical decisions is very important. Space technology can be particularly useful in the risk assessment, monitoring, response, mitigation and preparedness phases of disaster management, including early warning.... read more
Tropical storms have major impacts, including loss of life and destruction of property. In 2017 alone, the United States experienced three tropical storms with more than $1 billion in losses. Open source satellite data can be used before, during, and after a storm for monitoring and response. A storm’s intensity, path, wind, precipitation, storm surge, and flooding can be derived from historical and near real-time satellite observations. In this introductory webinar, participants will learn about the NASA data and tools they can use to monitor tropical storms.
Learning Objectives:
By the end of the training, attendees will be able to:
- Identify remote sensing data and tools relevant to tropical storms
- Monitor conditions before, during, and after a storm using remote sensing data
- Understand how remote sensing data can be used in decision-making activities
