IPRC scientists promote preparation for impending Pacific Islands drought

Honolulu, December 31, 2015
The El Niño of 2015-2016 is shaping up to be one of the strongest events since the phenomenon was recognized 60 years ago, predicted to bring heavy, flooding rains to the eastern Pacific, but excessive drought to the western Pacific basin. IPRC personnel, led by H. Annamalai, have investigated the effects on particularly vulnerable Pacific Islands, some of which are already feeling the results of the shifting weather: fresh water shortages, crop failures, depletion of fishing resources, heavier storm activity and increased risk in the spread of water- and insect-borne diseases. The authors present a number of strategies for short-term and long-term preparation and mitigation, as well as policy and educational resources. Read the full article to learn more about the team’s suggestions.

IPRC Senior Researcher Dr. Tangdong Qu leaving

Honolulu, December 23, 2015
This month, we bid a regretful farewell to Dr. Tangdong Qu, a senior researcher who was among the founding members of the IPRC, and whose research contributions have been impressive. He has explored ocean climate processes, examining the effects of the dynamics of the upper ocean on the larger ocean heat budget, as well as pursuing the effects of climate change on ocean circulation, particularly on the currents of the western Pacific. Dr. Qu has been an important member of the IPRC ‘ohana and will be greatly missed. We wish him the best of luck in his future pursuits at the Joint Institute for Regional Earth System Science and Engineering at UCLA.

IPRC group shows rapidly acidifying waters pose major threat for Southern Ocean ecosystem

Honolulu, November 2, 2015
As a result of increasing atmospheric carbon dioxide concentrations, the chemistry of the Southern Ocean is expected to change so fast over the next few decades that small, but important, creatures at the base of the food web may soon struggle to form their carbonate shells. For some organisms the onset of such critical conditions will be so abrupt, and the duration of events so long, that adaption may become impossible, according to new research by Claudine Hauri, at both the International Arctic Research Center (IARC) at the University of Alaska, Fairbanks and the IPRC, in collaboration with Tobias Friedrich and Axel Timmermann of IPRC.

New model by IPRC researchers explains near-annual Monsoon patterns generated by El Niño

Honolulu, October 19, 2015
The El Niño Southern Oscillation (called ENSO) is one of the most prominent climate events on the globe. Every two to seven years, temperature shifts cause modifications in wind and rainfall patterns in the Pacific, triggering changes in the climate around the world. A new study by Malte Stuecker and Fei-Fei Jin from Department of Atmospheric Sciences in collaboration with Axel Timmermann from IPRC present a new methodology which explores how interaction of the El Niño phenomenon with the annual cycle of solar radiation in the western Pacific generates a suite of predictable wind and rainfall patterns associated with the Southeast Asian Monsoons. In contrast to the inter-annual timescales of El Niño, monsoon oscillations occur on nearly annual timescales. The methodology provides a new way to explore atmosphere variability, as well as a number of other climate phenomena. Read the press release for more details.

IPRC Welcomes New Outreach Specialist

Helping Students Prepare for
Tracking Trash Robotics Competition

Honolulu, October 7, 2015
Jan Hafner has been busy helping student-groups prepare for the 2015 FIRST® LEGO League, which has the theme "TRASH TREKSM Challenge". His pictures and simulations let students understand how ocean debris moves through the gyres and collects in "garbage patches." He shows them real pieces that have drifted to Hawaii from the 2011 tsunami as well as other plastic debris of various shapes and sizes, including nearly invisible micro plastics.This all makes the students aware of the huge ocean debris problem. In the photo you see a group of 5th grade Punahou students with Hafner (right) and Nikolai Maximenko. Together with Kin Wang, Hafner held a similar session via Face Time with students at Holomua Elementary School.

IPRC Scientists show Frequency of El Niño-generated Sea Level Extremes to Increase with Effects of Climate Change

Honolulu, September 25, 2015
Gradual sea-level rise due to climate-induced melting of world-wide ice deposits is a well-known scenario at this stage, and many island nations in the tropical Pacific are already coping with the reality of an encroaching ocean. However, recent modeling research by IPRC scientists Matthew Widlansky and Axel Timmermann suggest that more frequent and extreme short-term sea level fluctuations may soon become an additional challenge. The new model incorporates the effects of a warming planet on the El Niño-La Niña phenomenon. The results show that intensified winds will double the frequency of the sea level fluctuations associated with these global weather patterns, particularly affecting the tropical southwestern Pacific. Read the press release for more details. Watch HawaiiNewsNow; and read Star-Advertiser, Climate Central, and Discovery News, and Hakai Magazine. Listen to Australian Broadcasting Station interview with Timmermann.

IPRC Director Returns from Central Pacific after Collecting Data during Developing El Niño

Honolulu, August 19, 2015
What happens to ocean mixing in the central equatorial Pacific during the developing phase of an El Niño ? This and other questions were at the forefront of IPRC Director Kelvin Richards' mind as he set out from Majuro in late July on the Research Vessel Falkor with a team of scientists from UH and Korea. The scientists collected data close to the equator and dateline on the flow structures that create turbulence and mixing. The team has returned to Honolulu onboard the vessel. Now we await the story that the analysis of these exciting measurements will tell about the causes of ocean mixing and its impact on the coupled ocean-atmosphere system. Read press release, and KITV 4 News, and Hawaii News Now and Radio Australia.

IPRC’s Axel Timmermann has been elected an American Geophysical Union Fellow. "Being elected a Union Fellow is a tribute to those AGU members who have made exceptional contributions to Earth and space sciences as valued by their peers and vetted by section and focus group committees. This honor is bestowed on only 0.1% of the membership in any given year," according to the EOS announcement. Timmermann and his 2015 American Geophysical Union Class of Fellows will be recognized at an award ceremony, held during the 2015 Annual AGU Fall Meeting in San Francisco, California.

IPRC Director Leads Scientific Team in Ocean Turbulence Study

Honolulu, July 21, 2015
IPRC Director Kelvin Richards heads out to the central equatorial Pacific to lead a science team from the University of Hawai`i, Seoul National University, and the Korean Institute for Ocean Science and Technology. On board the R/V Falkor operated by the Schmidt Ocean Institute, the team will gather data on small-scale turbulence in the region. Though coupling between the tropical ocean and atmosphere is known to be very dependent on the mixing produced by ocean turbulence, little is known about the mechanisms producing the turbulence. The new data set, combined with data from Richard’s previous work in other tropical Pacific regions, will let scientists determine more clearly what controls the mixing by turbulence. Among other things, the work will help improve the representation of ocean turbulence in models used to understand and forecast El Niño Southern Oscillations events (ENSOs). The Schmidt Ocean Institute and NSF are funding the three-week expedition. Read more.

Highest Carbon Dioxide levels ever recorded!

Honolulu, May 12, 2015
A recent NOAA report shows that the global mean carbon dioxide concentrations reached 400 parts per million in March - the highest level on record. IPRC’s Axel Timmermann, interviewed by Beth-Ann Kozlovich on Hawaii Public Radio, talked about the implications of this new record. The last time CO2 concentrations were this high was 4 - 5 million years ago, when the Greenland and West Antarctic ice sheets did not exist and sea level was at least 30 ft. higher than today. He spoke about the accelerating rate of CO2 emissions, the difficulty of communicating the science to climate-change deniers, and the enormous behavioral changes needed to avoid reaching the 2C global mean temperature threshold for dangerous climate change within 20 to 50 years. Listen to interview.

A strong El Nino in 2015?

Honolulu, May 11, 2015
Compared to last year’s ocean sea surface temperatures in the equatorial central-to-eastern Pacific, we are already in an El Ninio state, says IPRC’s Axel Timmermann in an interview with Cam Tran, KITV4 News. “It’s very likely that we’re going to have a strong El Ninio in the next 3-4 months” with a relatively wet summer and dry winter in Hawaii. It could also mean a higher generation of storms in the central Pacific. Watch news clip. More recently, Timmermann was interviewed also by CBS San Francisco. Listen to podcast.

Extending climate predictability beyond El Niño

Honolulu, April 21, 2015
Tropical Pacific climate variations and their global weather impacts may be predicted much further in advance than previously thought, according to research by IPRC's Yoshimitsu Chikamoto and Axel Timmermann and their international colleagues in the USA, Australia, and Japan. The source of this predictability lies in the tight interactions between the ocean and the atmosphere and among the Atlantic, the Pacific and the Indian Oceans. Such long-term tropical climate forecasts are useful to the public and policy makers.

Japanese high school students visit IPRC

March 5, 2015
The International Pacific Research Center once again welcomed 21 Japanese high school students and their 3 teachers. They were from Morioka Daisan High School. The purpose of their trip to Hawaii was to be exposed to spoken English in an academic environment with a science focus. Morioka, the capital of Iwate Prefecture, suffered much devastation in the March 2011 tsunami. The students thus listened attentively to the 90 minute powerpoint presentation by IPRC’s Jan Hafner about the IPRC tsunami and marine debris model and how the model was able to track the travels of the debris across the ocean to the North Pacific Coast, and some of it into the Great Garbage Patch and then onto the north-east facing shores of Hawaii.
