Researchers at U of T used nonlinear dynamics techniques to predict seizures and identified a dynamic regime - type III intermittency - that takes place during seizures. This approach may improve techniques to control the brain's transition to seizure, offering new hope for patients with intractable epilepsy.
The Colorado State University hurricane forecast team predicts a highly active 1999 hurricane season with landfall probabilities above average for the East Coast and Florida Peninsula. The team expects four major hurricanes with minimum winds of 111 mph, which historically cause most hurricane-spawned destruction.
Climate forecasts can have a mixed impact on different groups, with benefits for large fishing companies and losses for small-scale fishermen. Researchers are calling for better dissemination of climate information to address these issues.
A new heat-health watch/warning system will be installed in Rome by summer 2000, giving health officials up to 60 hours' notice of deadly weather. The system has already protected people from killer heat in Philadelphia and Washington D.C., and may be launched in Shanghai and other cities if effective.
Researchers can now forecast long-term climate cycles, such as the El Niño Southern Oscillation and Pacific Decadal Oscillation. By understanding these cycles, policymakers can develop strategies to lessen climate-related effects, potentially ensuring cultural survival.
The CloudSat spacecraft will produce detailed three-dimensional images of vertical cloud structures, missing from current weather forecasting models. Colorado State technology also contributes to a second NASA mission studying aerosols and thin clouds, enhancing climate change understanding.
The Colorado State University hurricane forecast team predicts 14 named storms, 9 hurricanes, and 4 intense hurricanes for the 1999 season. The U.S. Atlantic coast has a higher probability of being hit by major storms, with the Gulf Coast facing an increased risk of landfall.
The 1998 hurricane season saw a significant increase in storm frequency and intensity, with three hurricanes and four tropical storms making landfall along the US coastline. The season was attributed to warming ocean temperatures and changes in atmospheric circulation patterns.
A recent study suggests that El Nino events can be predicted several months in advance, with seasonal averages in the tropics being the most predictable. The research identifies sea surface temperature, soil wetness, vegetation, and snow cover as key factors influencing weather patterns.
The Aerosonde successfully completed the 2,000-mile, 26-hour trans-Atlantic flight, becoming the smallest aircraft to cross the Atlantic. The achievement marks a significant milestone in autonomous aviation and demonstrates the potential of unmanned aircraft as workhorses for the next century.
Researchers aim to prove robotic planes can operate autonomously over the Atlantic Ocean, improving weather forecasting. The autonomous aircraft will gather meteorological data for improved forecast accuracy and potentially detect severe weather.
A cost-benefit analysis found El Nino forecasting provides an annual economic return of 13-26% to the US agricultural industry, exceeding the government's minimum standard. The Tropical Ocean Global Atmosphere (TOGA) climate research program yields benefits worth $240-266 million annually.
Researchers have developed computer crop models to predict crop yields and prices, helping farmers make informed decisions before an El Niño event. The models combine weather and soil information with virtual farming decisions, allowing for tailored growing strategies that reduce risks and uncertainties.
Global climate factors point to more active storm era, with warmer sea surface temperatures and increased rainfall in the Sahel region. This trend contrasts with the most inactive four-year stretch within the same period, from 1991-94.
Researchers are collecting data from the lowest few thousand feet of the atmosphere, known as the boundary layer, to better understand its interactions with the surface. The Cooperative Atmosphere-Surface Exchange Study (CASES) aims to improve weather forecasting by measuring heating and evaporation rates at the surface.
A research team at Colorado State University predicts that the 1997 hurricane season will be above average, with 11 tropical storms expected to form. The team expects seven of these storms to become hurricanes, with three becoming major hurricanes, which cause 75% of all storm-spawned damage.
The study enhances lightning detection capabilities with total lightning measurements, providing more accurate forecasts of severe storms and storm morphology. This technology has the potential to improve space launch weather support and reduce delays or scrubs due to adverse weather conditions.
