Ocean salinities show an intensified water cycle
Public Release: CSIRO Australia
Evidence that the world’s water cycle has already intensified is contained in new research to be published in the American Journal of Climate.
The stronger water cycle means arid regions have become drier and high rainfall regions wetter as atmospheric temperature increases.
The study, co-authored by CSIRO scientists Paul Durack and Dr Susan Wijffels, shows the surface ocean beneath rainfall-dominated regions has freshened, whereas ocean regions dominated by evaporation are saltier. The paper also confirms that surface warming of the world’s oceans over the past 50 years has penetrated into the oceans’ interior changing deep-ocean salinity patterns.
“This is further confirmation from the global ocean that the Earth’s water cycle has accelerated,” says Mr Durack – a PhD student at the joint CSIRO/University of Tasmania, Quantitative Marine Science program.
“These broad-scale patterns of change are qualitatively consistent with simulations reported by the Intergovernmental Panel on Climate Change (IPCC).
“While such changes in salinity would be expected at the ocean surface (where about 80 per cent of surface water exchange occurs), sub-surface measurements indicate much broader, warming-driven changes are extending into the deep ocean,” Mr Durack said.
The study finds a clear link between salinity changes at the surface driven by ocean warming and changes in the ocean subsurface which follow the trajectories along which surface water travels into the ocean interior.
The ocean’s average surface temperature has risen around 0.4ºC since 1950. As the near surface atmosphere warms it can evaporate more water from the surface ocean and move it to new regions to release it as rain and snow. Salinity patterns reflect the contrasts between ocean regions where the oceans lose water to the atmosphere and the others where it is re-deposited on the surface as salt-free rainwater.
“Observations of rainfall and evaporation over the oceans in the 20th century are very scarce. These new estimates of ocean salinity changes provide a rigorous benchmark to better validate global climate models and start to narrow the wide uncertainties associated with water cycle changes and oceanic processes both in the past and the future – we can use ocean salinity changes as a rain-gauge,” Mr Durack said.
Based on historical records and data provided by the Argo Program’s world-wide network of ocean profilers – robotic submersible buoys which record and report ocean salinity levels and temperatures to depths of two kilometres – the research was conducted by CSIRO’s Wealth from Oceans Flagship and partially funded by the Australian Climate Change Science Program. Australia’s Integrated Marine Observing System is a significant contributor to the global Argo Program.

How El Niño and La Niña affect Rainfall
El Niño 1997
La Niña, 1988
El Niño and its counterpart La Niña alter weather patterns across the world. These images show the strongest El Niño and La Niña events of the past twenty years and their impact on rainfall over North and South America.
The top image pair shows the El Niño event of 1997, and the direct correlation between warm surface waters and rainfall. The 1997 El Niño was unusually strong and brought heavy rain to northwest South America and the southern United States. Cooler ocean temperatures caused drought in Australia and Indonesia, as shown in the 1997 rainfall anomaly image.
The lower image pair shows La Niña in 1988 . La Niña occurs when the eastern Pacific off the coast of South America cools. The unusually cold ocean cools the atmosphere above it. The cool, dense air means less rain falls over the cold waters in the eastern equatorial Pacific. Image reveals that the drought reached Peru and Ecuador in northwest South America. Globally, La Niña causes unusually heavy rain in India, Southeast Asia, Australia, and southeastern Africa.

Drought is the biggest environmental catastrophe facing Africa
A weak rainy season lead to water food shortages in most parts of Africa, especially Kenya, which entered a state of emergency with about a third of the country’s 32 million population requiring food aid.
The drought also meant low water levels in reservoirs, water rationing and power cuts. The Masinga hydroelectric dam was closed down after low water levels in the reservoir could not sustain power generation.
The following images show how plants responded to the poor rainfall during the rainy season in 2009.
Drought in Africa
Rainfall Anomaly (2009 season)
Cumulative Rainfall, Masinga Dam, Kenya
Africa’s Sahel region, a belt of fertile grassland, thrives or fails depending on seasonal rainfall. In dry years, little grows, and those who depend on rain to grow crops in the Sahel may face hunger.
Above images show rainfall during the long rainy season in 2009. The top image, made from data collected by the Advanced Very High Resolution Radiometer (AVHRR) flying on the National Oceanic and Atmospheric Administration’s Polar Orbiting Environmental Satellite NOAA-17, shows the condition of plants in June 2009 compared to previous Junes. In areas that are brown, plants were growing less then the 2003 and 2008 average. Green areas indicate better-than-average growth, while cream-colored areas indicate about average growth.
The poor growth in June 2009 is a result of the weak rainy season. Low seasonal rains, which usually come between March and June, resulted in drought this year. Made from a combination of satellite and rain gauge measurements, the middle image shows the extent of the rainfall deficit between March and June. Areas in brown received less rain than average, while blue areas received more rain. The average was calculated from rainfall observed between March and June from 1995 through 2008. The northern Sahel and East Africa were drier than normal throughout the 2009 rainy season.
The graph illustrates why water levels were so low at Masinga Dam in 2009 compared to the long-term average and other recent years. Each line shows how the rainy season developed between March and June. 1997 was an unusually wet year, with about 75 millimeters more rain than average by the end of June. The last year when rainfall reached normal levels was 2006. In 2009, the rainy season didn’t start until late March and less rain fell throughout the season. By the end of June, Masinga Dam had only received about 100 millimeters of rain, about 125 mm less than average and 200 mm less than in 1997. If conditions improve, Kenya’s next rainy season will likely begin in September or October and will last through November or December.

Warm Waters in the S and SW Coast of Cuba Await Gustav
Real Time POES Composite Imagery Atlantic/East Pacific
(Daily Sea Surface Temperatures)
Image Source: NOAA
Warm waters in the 30-35ºC temp. range (shown in firebrick red) surrounding the south and southwestern coast of Cuba await hurricane Gustave as it leaves Haiti. Gustav may strengthen into a cat. three/four hurricane.
NHC Hurricane GUSTAV Forecast Discussion (No. 7):
Center of Gustav made landfall around 17:30 UTC. A minimum pressure of 992 mb was reported just as the center moved inland. As the center is moving over the mountainous terrain of the southwest peninsula of Haiti, Gustav is likely losing strength. The eye is no longer evident on satellite images, and the system could weaken below hurricane intensity tonight. However, the upper-level environment remains favorable for intensification with only a little north-northeasterly shear, and therefore Gustav is likely to regain strength as it approaches the Windward Passage and eastern Cuba tomorrow.

Latest News Update:
“Given the current track for Gustav and the expectation that it might enter the Gulf of Mexico this weekend, we are making logistical arrangements to evacuate staff who are not essential to production or drilling operations,” Shell said in a statement.
“Evacuations could begin as early as Wednesday. There is no impact on production at this time.” (Source: AFP)

Coastal Watches/Warnings and 5-Day Track Forecast Cone – NOAA/NWS
This graphic shows an approximate representation of coastal areas under a hurricane warning (red), hurricane watch (pink), tropical storm warning (blue) and tropical storm watch (yellow). The orange circle indicates the current position of the center of the tropical cyclone. The black line and dots show the National Hurricane Center (NHC) forecast track of the center at the times indicated. The dot indicating the forecast center location will be black if the cyclone is forecast to be tropical and will be white with a black outline if the cyclone is forecast to be extratropical. If only an L is displayed, then the system is forecast to be a remnant low. The letter inside the dot indicates the NHC’s forecast intensity for that time. NOAA-NWS
These graphics show probabilities of sustained (1-minute average) surface wind speeds equal to or exceeding 64 kt…74 mph (hurricane force). These wind speed probability graphics are based on the official National Hurricane Center (NHC) track, intensity, and wind radii forecasts, and on NHC forecast error statistics for those forecast variables during recent years. Each graphic provides cumulative probabilities that wind speeds of at least 74 mph will occur during cumulative time periods at each specific point on the map. The cumulative periods begin at the start of the forecast period and extend through the entire 5-day forecast period at cumulative 12-hour intervals (i.e., 0-12 h, 0-24 h, 0-36 h, … , 0-120 h). An individual graphic is produced for each cumulative interval, and the capability to zoom and animate through the periods is provided. To assess the overall risk of experiencing winds of at least 74 mph at any location, the 120-h graphics are recommended. NOAA-NWS
Gustav Could Become a Cat. Two Hurricane Before Landfall in Haiti
Gustav became stronger as it neared the south coast of Haiti, NHC reported. Here’re the highlights of NHC Hurricane Advisory:
- A hurricane warning remains in effect from Barahona in the Dominican Republic westward to Le Mole St Nicholas Haiti.
- A hurricane watch is also in effect for the Cuban provinces of Las Tunas, Granma, Holguin, Santiago de Cuba and Guantanamo. A hurricane watch is also in effect for Jamaica.
- At 8:00 am EDT the center of hurricane Gustav was located near latitude 17.5 north, longitude 72.0 west or about 125 km south-southeast of Port Au Prince Haiti and about 425 km southeast of Guantanamo Cuba.
- Gustav continues moving toward the northwest at 15 km/hr today with a turn toward the west-northwest and a decrease in forward speed forecast on Wednesday. On this track this hurricane should move over Southwestern Haiti later today and near or just south of Eastern Cuba on Wednesday.
- Maximum sustained winds have increased to near 150 Km/hr with higher gusts. Gustav is a category one hurricane on The Saffir-Simpson scale. The hurricane could become a category Two hurricane before landfall in Haiti later today.
- Hurricane force winds extend outward up to 35 km from the center, and tropical storm force winds extend outward up to 110 km.
- The latest minimum central pressure is 981 mb (28.97 inches).

Rainfall accumulations of 4 to 7 inches over southern Hispaniola and Jamaica with isolated maximum amounts of up to 15 inches are possible. These rains may produce life-threatening flash floods and mud slides. — Forecaster Brown/Pasch
“Oil prices in Asia rose Tuesday on concerns Hurricane Gustav may disrupt oil operations in the Gulf of Mexico.” AP reported.
“It’s hard to predict where Gustav will strike,” an analyst in Singapore reported. “But the market is reacting to it and edging up some.”
“Light, sweet crude for October delivery was up 58 cents at $115.69 a barrel in electronic trading on the New York Mercantile Exchange by midafternoon in Singapore. The contract rose 52 cents overnight to settle at $115.11 a barrel.”
On its forecast track and anticipated strength, Gustav could cause significant disruptions to offshore oil operations in the Gulf of Mexico.

A Shrinking World Series
How Much More Floodwaters, Trash Before the Truth Sinks In?
As the Campania region in southwest italy is buried deeper in trash, the northwestern region of Piedmont, another of the country’s 20 regions, is submerged in floodwaters. The authorities declared a state of emergency in Turin and Val d’Aosta.
[Darn, I wonder what caused that!] A man surveys the damage caused by a landslide caused in Turin. (Photo: AFP) Image may be subject to copyright. See FEWW Fair Use Notice!
Eyewitnesses reported a five-meter high wall of mud engulfing houses in an Alpine village near the French border. A landslide caused by heavy rainfall has killed at least three people; a 3-year old girl was reported missing.
The floods also pose a serious risk to crops in the area. “The torrential rain and the Po [Italy’s longest river] and the Dora breaking their banks have meant many wheat fields are flooded and the harvest could be lost,” the Italian Farmers Confederation said in a statement.
The Po valley, Italy’s most fertile farming area, is also its most industrially developed. “There has been too much building, concreting-over and canalization along our rivers with devastating consequences that happen as soon as rains start,” said Michele Candotti of the Environmental group WWF Italia.
