Japan Landslide kills tens of people

As of this morning, Wednesday 20th August, 32 people have been confirmed dead after heavy rainfall last night resulted in multiple landslides in the Japanese city Hiroshima.

The unexpected large low pressure over the region last night resulted in 10 inches of rainfall falling in just a few hours. The rain initiated a series of landslides that swept down the mountain towards Hiroshima.

Hawaii prepares for its first hurricane in 22 years

Pacific Hurricane Iselle is due to strike the Big Island of the Hawaii island chain sometime today.

Forecasters initially thought that Iselle would reduce in intensity to a large tropical storm before it hit the island. However weather officials changed their outlook after Iselle became slightly stronger and was able to maintain its hurricane classification.

The island chain is preparing for strong winds and heavy rainfall. This is the first hurricane strength storm to strike Hawaii in 22 years.

Another Pacific storm further to the east, Hurricane Julio, is strengthening and heading towards the island chain. Julio is expected to approach Hawaii closer to the weekend. Forecasters predict that it might pass to the north of the island chain. However the rainfall from two events in such close proximity could result in widespread flash flooding.

Keep an eye on the NOAA website for updates on the storm risks.

How can we weigh a cloud?

JimCGS air quality expert Dr Jim McQuaid has been filming a BBC two-part documentary Operation Cloud Lab: Secrets of the Skies. The documentary follows a team of scientists as they explore the earth’s atmosphere, travelling in an airship. The expedition begins with an examination of clouds and how we can determine the weight of an average cloud.You might be surprised at the result!

You can watch the first episode on BBC iplayer.

How polluted is the air you’re breathing?

air_quality_map-The_Atlantic

The Atlantic has recently published a global map of air quality. Take a look at the interactive map to find out how the quality of the air you’re breathing compares with other countries and cities.The news isn’t good if you’re in China, India, Nepal, Pakistan, and Bangladesh.

The map overlays two sources of data on air pollution: for cities, the World Health Organization’s ambient (outdoor) air pollution in cities database 2014; for countries, ground-level exposures to fine particulate matter (PM2.5) are derived from satellite measures used in the 2014 Environmental Performance Index, a biennial global ranking produced by Yale and Columbia researchers that compares countries on high-priority environmental issues.

Japan hit by Super Typhoon Neoguri

typhoon_neoguriThe violent super typhoon Neoguri is possibly the most powerful typhoon to strike Japan in 15 years. With expected wind gusts of 170 miles per hour and 75 millimetres of rain per hour the typhoon is battering the southern islands of Okinawa this morning.

Neoguri is forecast to continue northwards over land passing over the southern island of Kyushu and onto central Japan slowly losing energy along the way.

Typhoon Neoguri is carrying a huge amount of moisture. When it hits the mainland much of that will be released as rain, which could unleash flash floods and trigger landslides, our correspondent adds. Storm surge wave heights of 12 metres are expected raising fears of further coastal flooding.

Check out one of our earlier posts for a discussion of how these large cyclonic storms form.

Twin Tornadoes hit Nebraska, United States

Twin tornadoes are an exceptionally rare weather phenomenon. Two large tornadoes hit the town of Pilger in the U.S. state of Nebraska last Monday, 16th June.

The video above shows the two violent tornadoes ripping through the countryside. The BBC reports that at least one person is dead and at least 19 are hurt.

Check out our earlier post for more information on tornadoes, how they form and how their strength is calculated.
