More Details about this video animation The video animation shows the near surface (10m) winds and
rainfall intensity over the Gulf of Mexico and the surrounding land areas during the main development phase of Hurricane Katrina, August 24 - 30, 2005, based on NCEP - GFS forecast model analyses.
Work by researchers from Taiwan and China found that the increase in
rainfall intensity over the past three decades has been an entire order of magnitude greater...
Not exact matches
The analysis demonstrated a decline in
rainfall intensity, despite an increase in total
rainfall over the years.
«They are becoming more concentrated
over a smaller area, and the
rainfall is coming down more plentifully and with more
intensity over a shorter period of time.
This lower -
intensity rainfall implies less runoff
over the surface, which means we should see a decline in runoff
over a whole basin.
According to the latest IPCC report, «tropical cyclone frequency is likely to decrease or remain unchanged
over the 21st century, while
intensity (i.e. maximum wind speed and
rainfall rates) is likely to increase.»
Further complicating the use of these proxies is the fact that the deviation in oxygen - 18 ratios is affected by the amount of TC
rainfall, the distance from the center of the cyclone at which the rain was produced, and the
intensity of the cyclone — so I doubt these proxies alone will enable disentangling
intensity and
rainfall, tnough a large number of samples
over an area could reveal information about the track and extent of the TC event.
The intense
rainfall was due to a complicated interplay between the
intensity of the hurricane, its path, and the fact that it stalled
over the coast with part of it still
over the water so the storm dynamics could access the heat and moisture of the Gulf.
Over the coming decades, Atlantic hurricanes are likely to increase in strength as sea surface temperatures increase, fueling the intensity of storms in the Atlantic Ocean, and significantly increasing rainfall rates over those of present day sto
Over the coming decades, Atlantic hurricanes are likely to increase in strength as sea surface temperatures increase, fueling the
intensity of storms in the Atlantic Ocean, and significantly increasing
rainfall rates
over those of present day sto
over those of present day storms.
The climate change has visible signs in Pakistan, which include hotter summers, early cold spell, monsoon irregularity with untimely
rainfall, increased
rainfall over short period causing water logging, increased frequency and
intensity of floods — especially recent floods, which destroyed livelihoods in Punjab and Sindh districts — very little
rainfall in dry period, crop failure due to drought and salinity intrusion along the coastal region.
Over the past 1000 years we have seen a El Nino peak followed by centuries of high La Nina frequency and
intensity — and higher
rainfall in Australia — until the 20th century.
