Rainfall - Blog Posts

Sean bienvenidos, japonistasarqueológicos a una nueva entrega, en esta ocasión hablaré sobre actualidad nipona, una vez dicho esto pónganse cómodos que empezamos. — El domingo 16 de julio, azotaron fuertes lluvias al archipiélago nipón y hace no mucho el tifón Lan paralizó el tráfico aéreo de Japón y dejó miles de evacuados al oeste, además sin electricidad. Pero en este caso se han anegado muchas zonas del norte, causando efectos geográficos catastróficos y causando evacuaciones, etc. Por ejemplo: La ciudad de Akita registró precipitaciones, fue un récord, más de 250 milímetros durante un período de 48 horas, todo un hito histórico. — Espero que os guste y nos vemos en próximas publicaciones, que pasen una buena semana. - Welcome, Japanese archaeologists, to a new installment, this time I will be talking about Japanese current affairs, and once that is said, make yourselves comfortable and let's get started. - On Sunday 16th July, heavy rains hit the Japanese archipelago and not long ago Typhoon Lan paralysed Japan's air traffic and left thousands of evacuees in the west without electricity. But in this case many areas in the north have been flooded, causing catastrophic geographical effects and causing evacuations, etc. For example: The city of Akita recorded record rainfall of more than 250 millimetres over a 48-hour period, a historic milestone. - I hope you like it and see you in future posts, have a good week. - 日本の考古学者たちよ、新しい回へようこそ。今回は日本の時事問題についてお話しします。そう言ったら、くつろいで、始めましょう。 - 7月16日の日曜日、日本列島は大雨に見舞われ、少し前には台風12号が日本の空の便を麻痺させ、西日本では何千人もの避難者が停電に見舞われた。しかし今回は、北部の多くの地域が浸水し、地理的に壊滅的な影響を引き起こし、避難などを余儀なくされている。例えば：秋田市では、48時間に250ミリ以上の記録的な雨量を記録し、歴史的な出来事となった。 - お気に召していただけたなら幸いである.

I was getting overwhelmed by everything when I originally made this on paper. I liked how the waves looked, so I decided to turn it digital.

Land is Sliding, Tell Us Where!

Summer in the northern hemisphere brings monsoon season, causing heavy rains and flooding that trigger landslides. Next time you see a landslide in the news, online, or in your neighborhood, submit it to our citizen science project Landslide Reporter to build the largest open global landslide catalog and help us and the public learn more about when and where they occur.

Rainfall is the most common cause of landslides.

After a storm, the soil and rock on a slope can become saturated with water and begin to slide downwards, posing a danger to people and destroying roads, houses and access to electricity and water supplies.

We have been monitoring rainfall from space for decades.

Orbiting the Earth right now, the Global Precipitation Measurement (GPM) mission is a group of 10 satellites that measure rain, snow, sleet and other precipitation worldwide every three hours. This data tells us where and when heavy rain is falling and if it could lead to disasters.

What can rainfall data tell us about landslides?

We're using GPM data to understand where and when landslides are happening. A global landslide model uses information about the environment and rainfall to anticipate where landslides are likely to happen anytime around the world every three hours.

To improve the global landslide model and other landslide research, NASA is looking for citizen scientists like you!

If you find a landslide reported online or in your neighborhood, you can provide the event details in Landslide Reporter, our citizen science project.

Your detailed reports are added into an open global landslide inventory available at Landslide Viewer. We use citizen science contributions along with other landslide data to check our prediction model so we can have a better picture of how rainfall, slope steepness, forest cover, and geology can trigger a landslide.

Because the data is open, anyone can use the data for research or response.

When you report a landslide, you improve our collection of landslide data for everyone.

Help support landslide efforts worldwide by contributing to Landslide Reporter, and you can help inform decisions that could save lives and property today! Learn more about the project at https://landslides.nasa.gov. You can also follow the project on Twitter and Facebook.

The 2017 Atlantic Hurricane Season: What We Learned

The 2017 Atlantic hurricane season was among the top ten most active seasons in recorded history. Our experts are exploring what made this year particularly active and the science behind some of the biggest storms to date.

After a period of 12 years without a Category 3 or higher hurricane making landfall in the U.S., Hurricane Harvey made landfall over Texas as a Category 4 hurricane this August.

Harvey was also the biggest rainfall event ever to hit the continental U.S. with estimates more than 49 inches of rain.

Data like this from our Global Precipitation Measurement Mission, which shows the amount of rainfall from the storm and temperatures within the story, are helping scientists better understand how storms develop. 

The unique vantage point of satellites can also help first responders, and this year satellite data helped organizations map out response strategies during hurricanes Harvey, Irma and Maria. 
 

In addition to satellites, we use ground stations and aircraft to track hurricanes.

We also use the capabilities of satellites like Suomi NPP and others that are able to take nighttime views. In this instance, we were able to view the power outages in Puerto Rico. This allowed first responders to see where the location of impacted urban areas.

The combined effort between us, NOAA, FEMA and other federal agencies helps us understand more about how major storms develop, how they gain strength and how they affect us.

Studying Storms from Air and Space

Technology we’ve developed is helping study the movement of storms.  

From satellites that can slice through a hurricane with 3-D vision to computer models of gale force winds, scientists now have unprecedented ways of viewing extreme weather.

This August, we’re sending an unmanned aircraft called a Global Hawk to study hurricanes. This mission is called the “East Pacific Origins and Characteristics of Hurricanes,” or EPOCH. It will fly over developing tropical storms to investigate how they progress and intensify. 

The three instruments aboard this Global Hawk aircraft will map out 3-D patterns of temperature, pressure, humidity, precipitation and wind speed as well as the role of the East Pacific Ocean in global cyclone formation. These measurements will help scientists better understand the processes that control storm intensity and the role of the East Pacific Ocean in global cyclone formation.

To better understand hurricane formation and intensity, scientists also utilize models and other observations.

Satellites such as our Global Precipitation Measurement Mission, or GPM, and computer models can analyze key stages of storm intensification.  

In September 2016, GPM captured Hurricane Matthew’s development from a Category 1 to Category 5 hurricane in less than 24 hours.  

Extreme rainfall was seen in several stages of the storm, causing significant flooding and landslides when it passed by Cuba, Haiti and the Dominican Republic.

By combining model and observed data, scientists can analyze storms like never before. They can also better understand how hurricanes and other powerful storms can potentially impact society.
