![]() ![]() Such storm surges are of course affected by ongoing sea level rise, but this is not yet part of our attribution assessment. Note also that in addition to direct impacts of wind and rain, Florence is expected to cause a large storm surge. ![]() More analyses are needed to assess the robustness of this quick analysis, although the basic result that global warming increases the precipitation is a very robust one supported by observations and modelling studies (e.g. Once matched, its possible to estimate wind speed. The results of such a study not only depend on the general effect of climate change on precipitation of hurricanes, but also on the details of this particular hurricane and even the forecast model. Meteorologists match satellite imagery of a storm to known patterns. Whereas we compute the change in probability of a class of events, such as all events with extreme rainfall above a certain limit, their study investigates only this specific event (more precisely, one forecast of the event). Astronaut Ricky Arnold, from aboard the International Space Station, shared this image of Hurricane Florence on Sept. They use a different technique from our regular WWA analyses, which answers a slightly different question. One analysis of the forecast strength of Florence has already been made public by Reed et al. We would strongly welcome partners that can support our work and enable our impactful analyses. ![]() We have no stable funding at the moment and cannot do this analysis “on the side” together with the ongoing analysis of the Kerala floods and the normal work. Lack of manpower in the WWA consortium.We have only a single model ready with the required resolution for this region and a solid analysis requires multiple large ensembles of high-resolution models.Hurricanes are also rare here so we have to combine different areas along the coast to ascertain whether they fit the distribution of other extreme rain events (like happened in the Gulf) or behave differently than the rest. There is a gradient in hurricane activity along the coast and there are mountains with strongly varying rainfall amounts. The observational analysis - looking at similar events in the past - will be much harder.This analysis would be more challenging for three reasons: NASA image created by Jesse Allen, Earth Observatory, using data provided courtesy of the MODIS Rapid Response team.We have investigated the possibility of doing a World Weather Attribution (WWA) analysis of the effect of climate change on the rainfall, similar to the one we did for Harvey last year ( van Oldenborgh et. It brought strong storm surge to the Canadian coast. By September 15, Florence had traveled far enough north for the storm to be classified as extra tropical (outside the tropics). Florence had sustained winds of around 100 kilometers per hour (65 miles per hour) at the time this satellite image was acquired, according to the University of Hawaii’s Tropical Storm Information Center.įlorence brought powerful winds, rain, and surf to Bermuda as the storm passed as close as 100 kilometers (60 miles) to the island, according to Reuters. Florence at the time of this image was a large, open swirl spread over a wide area of the northern Atlantic Ocean. This photo-like image was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Terra satellite on September 14, 2006, at 9:50 a.m. By September 11, 2006, it had become a Category 1 hurricane. Florence started as a tropical depression (area of low air pressure) north and east of the South American coast on September 3, growing in power and size gradually. Hurricane Florence was the sixth named storm of the 2006 Atlantic Hurricane Season.
