The cost of water

Posted by feww on March 23, 2016

How much water do you need?

Worldwide, some 650 million people are without clean water and more than 2.3 billion people have no access to basic sanitation, says a new report.

The World Health Organization (WHO) recommends 50 liters of water per person per day as the ‘intermediate’ quantity needed to maintain health, hygiene and for all domestic uses.

But how much does 50 liters of water cost?

  • Cost In Port Moresby, Papua New Guinea – 50l of water bought from a delivery service:
    £1.84 [54% of typical low daily salary for a snack stall-holder]
    [£1.00 (GBP) = $1.41 (USD) today.]
  • In Antananarivo, Madagascar – from a tanker truck:
    £0.50 [45% of typical low daily salary for a factory worker]
  • In Accra, Ghana – from a tanker truck:
    £0.45 [25% of typical low daily salary for a street food-seller]

In India it can cost up to a fifth of the daily wage to buy a day’s worth of water!

  • In Maputo, Mozambique – from a street vendor:
    £0.09 [13% of typical low daily salary for a street food-seller]
  • In London, UK – from an official piped supply:
    £0.07 [0.15% of typical low daily salary for a person on minimum wage]

El Niño Weekly Update [7 Dec 2009]

Posted by feww on December 8, 2009

ENSO Cycle: Recent Evolution, Current Status and Predictions

The following UPDATE is prepared by Climate Prediction Center / NCEP –  7 December 2009

The latest weekly SST departures are:

  • Niño 4   ~  1.4ºC
  • Niño 3.4  ~  1.7ºC
  • Niño 3 ~ 1.4ºC
  • Niño 1+2 ~ 0.4ºC


El Niño Map. [SOURCE: NOAA/ Climate Prediction Center / NCEP]

SST Departures (°C) in the Tropical Pacific During the Last 4 Weeks
During the last 4-weeks, SSTs were at least 1.0°C above average across much of the equatorial Pacific and more than 2.0°C above average between 180°and 130°W.

Global SST Departures (°C)
During the last four weeks, equatorial SSTs were above-average across the Pacific and Indian Oceans. Also, above-average SSTs covered large areas of the Northern Hemisphere subtropics.

Weekly SST Departures (°C) for the Last Four Weeks

  • During the last four weeks, positive SST anomalies persisted across the central and eastern equatorial Pacific Ocean.
  • During the last 30 days, equatorial SST anomalies only changed in small regions across the equatorial Pacific.

Sub-Surface Temperature Departures (°C) in the Equatorial Pacific

  • During October –November 2009, positive temperature anomalies at thermocline depth increased and expanded eastward across the eastern equatorial Pacific, in response to the downwelling phase of an oceanic Kelvin wave.
  • The most recent period indicates the eastward expansion of positive anomalies has slowed in the eastern Pacific Ocean.

Atmospheric Circulation over the North Pacific & North America During the Last 60 Days
See:
El Niño Update [30 Nov 2009]

Weekly Heat Content Evolution in the Equatorial Pacific

(A) The negative anomalies weakened during January-March 2009, with positive anomalies becoming established in late March.

(B) In April 2009, the combined effects of an oceanic Kelvin wave and weaker-than-average easterly trade winds contributed to an increase in the upper-ocean heat content anomalies across the Pacific Ocean.

Since April 2009, heat content anomalies have remained above-average, but there has been considerable month-to-month variability due to Kelvin wave activity.

(C) During November, the downwellingphase of a Kelvin wave contributed to an increase in heat content.

Oceanic Kelvin waves have alternating warm and cold phases. The warmp hase is indicated by dashed lines. Down-welling and warming occur in the leading portion of a Kelvin wave, and up-welling and cooling occur in the trailing portion.

Low-level (850-hPa) Zonal (east-west) Wind Anomalies (m s -1)
From April-October 2009, the MJO was weak to nonexistent. Since May 2009, westerly wind anomalies have covered large portions of the equatorial Pacific, except near the Date Line.During November 2009, the MJO became active, which contributed to anomalous easterlies shifting eastward from the Indian Ocean to the central and eastern Pacific. Recently, westerly anomalies have returned across much of the equatorial Pacific Ocean.

Summary

  • El Niño is present across the equatorial Pacific Ocean.
  • Sea surface temperatures (SST) are at least 1.0ºC-2.0ºC above-average across much of the central and east-central equatorial Pacific.
  • Based on current observations and dynamical model forecasts, El Niño is expected to last through at least the Northern Hemisphere winter2009-10.

Tropical OLR and Wind Anomalies During the Last 30 Days

TOP: Positive OLR anomalies (suppressed convection and precipitation, red shading) were present over Indonesia, Malaysia, Papua New Guinea, and Australia. Negative OLR anomalies (enhanced convection and precipitation, blue shading) were located over the western tropical Pacific Ocean just southeast of Papua New Guinea.
Middle: Low-level (850-hPa) westerly anomalies remained over the east-central equatorial Pacific.
Above: Upper-level (200-hPa) easterly anomalies were observed across the eastern equatorial Pacific. An anticycloniccouplet was evident in the subtropics of both hemispheres, which is consistent with El Niño.

Atmospheric Circulation over the North Pacific & North America During the Last 60 Days
During October, a nearly zonal pattern of below-average heights over the mid-latitudes was observed with an anomalous ridge over Alaska and the higher latitudes. This pattern contributed to below-average temperatures across Canada and much of the U.S. During November, the anomalous zonal pattern of below-average heights at mid-latitudes had been replaced by strong anomalous ridges across the N. Pacific and much of N. America with below-average heights across Alaska. This pattern has led to above-average temperatures across much of Canada and the United Statesand below-average temperatures in Alaska.

Intraseasonal Variability

  • Intraseasonal variability in the atmosphere (wind and pressure), which is often related to the Madden-Julian Oscillation (MJO), can significantly impact surface and subsurface conditions across the Pacific Ocean.
  • Related to this activity
    • Significant weakening of the low-level easterly winds usually initiates an eastward-propagating oceanic Kelvin wave.
    • Several Kelvin waves have occurred during the last year (see next slide).

Summary

  • El Niño is present across the equatorial Pacific Ocean.
  • Sea surface temperatures (SST) are at least 1.0ºC-2.0ºC above-average across much of the central and east-central equatorial Pacific.
  • Based on current observations and dynamical model forecasts, El Niño is expected to last through at least the Northern Hemisphere winter2009-10.

    The latest weekly SST departures are:

    • Niño 4   ~  1.5ºC
    • Niño 3.4  ~  1.7ºC
    • Niño 3 ~ 1.2ºC
    • Niño 1+2 ~ 0.5ºC


    El Niño Map. [SOURCE: NOAA/ Climate Prediction Center / NCEP]

    SST Departures (°C) in the Tropical Pacific During the Last 4
    During the last 4-weeks, SSTs were at least 1.0°C above average across much of the equatorial Pacific and more than 2.0°C above average between 175°E and 140°W.

    Global SST Departures (°C)
    During the last four weeks, equatorial SSTs were above-average in the Pacific and Indian Oceans. Also, above-average SSTs covered large areas of the Northern Hemisphere subtropics.

    Weekly SST Departures (°C) for the Last Four Weeks

    • During the last four weeks, equatorial SST anomalies strengthened across the central and eastern Pacific Ocean.
    • During the last 30 days, equatorial SST anomalies increased across much of the central and eastern Pacific.

    Central & Eastern Pacific Upper-Ocean (0-300 m) Weekly Heat Content Anomalies
    Since April 2009, the upper-ocean heat content has been above average across
    the eastern half of the equatorial Pacific Ocean. The heat content was previously below-average from mid-August 2008 through March 2009, with a minimum reached in late December 2008.

    Sub-Surface Temperature Departures (°C) in the Equatorial Pacific

    • During late September – early November 2009, temperature anomalies at thermocline depth increased and expanded eastward across the central and east-central equatorial Pacific, in response to the downwelling phase of an oceanic Kelvin wave.
    • The most recent period (below) shows a continued eastward expansion of positive anomalies in the equatorial Pacific near 50 – 150m depth.

    Tropical OLR and Wind Anomalies During the Last 30 Days

    • Positive OLR anomalies (suppressed convection and precipitation, red shading) were present over Indonesia, Malaysia, Papua New Guinea, and Australia. Negative OLR anomalies (enhanced convection and precipitation, blue shading) were located over the western tropical Pacific Ocean just southeast of Papua New Guinea.
    • Low-level (850-hPa) westerly anomalies were observed over the east-central equatorial Pacific.
    • Upper-level (200-hPa) easterly anomalies were observed across most of the equatorial Pacific. Anomalous anticyclones were evident in the subtropics of both hemispheres, which is consistent with El Niño.

    Atmospheric Circulation over the North Pacific & North America During the Last 60 Days
    From mid-September through October, anomalous troughing was prevalent over the North Pacific Ocean. During October, the pattern of below-average heights became more zonal over the mid-latitudes and an anomalous ridge developed over the higher latitudes. This pattern contributed to below-average temperatures across Canada and much of the U.S. Since early November, the anomalous zonal pattern of below-average heights at mid-latitudes has been replaced by anomalous ridges with below-average heights across the northernmost latitudes. This pattern has led to above-average temperatures across much of Canada and the United States.

    Summary

    • El Niño is present across the equatorial Pacific Ocean.
    • Sea surface temperatures (SST) were at least 1.0ºC above-average across much of the central and east-central equatorial Pacific.
    • Based on current observations and dynamical model forecasts, El Niño is expected to continue to strengthen and last through at least the Northern Hemisphere winter 2009-10.

    Sub-Surface Temperature Departures (°C) in the Equatorial Pacific

    • During mid September –October 2009, temperature anomalies increased and expanded eastward in the central equatorial Pacific at thermoclinedepth, due to the downwelling phase of a Kelvin wave.
    • The most recent period (below) shows a continued eastward expansion of positive anomalies in the central Pacific near 100-150m depth.

    Atmospheric Circulation over the North Pacific & North America During the Last 60 Days
    In late September and early October, an anomalous ridge developed over the Gulf of Alaska, with a downstream trough and below-average temperatures over parts of the U.S. During mid October, the pattern became more zonal with an anomalous trough evident over the mid-latitudes and an anomalous ridge over the higher latitudes. This pattern contributed to below-average temperatures across Canada and the eastern half of the U.S. Recently, anomalous ridges emerged over the eastern North Pacific and eastern U.S. leading to above-average temperatures over the western and eastern U.S.

    Low-level (850-hPa) Zonal (east-west) Wind Anomalies (m s-1)

    • Since April 2009, the MJO has been weak.
    • Since May 2009, westerly wind anomalies have covered large portions of the equatorial Pacific, except near the Date Line.
    • Recently, the largest westerly wind anomalies have been observed across the eastern Pacific Ocean.

    Summary

    • El Niño is present across the equatorial Pacific Ocean.
    • Sea surface temperatures (SST) were at least 1.0ºC above-average across much of the central and east-central equatorial Pacific.
    • Based on current observations and dynamical model forecasts, El Niño is expected to continue to strengthen and last through at least theNorthern Hemisphere winter 2009-10.

    Pacific Niño 3.4 SST Outlook

    • Most ENSO models indicate El Niño will continue through the Northern Hemisphere winter 2009-10.
    • The models disagree on the eventual strength of El Niño (SST anomalies ranging from +0.5°C to greater than +2.0°C), but a majority indicate at least a moderate strength El Niño (greater than +1.0°C) during November-December-January 2009-10.

    SST Outlook: NCEP CFS Forecast Issued 1 November  2009
    The CFS ensemble mean predicts El Niño will last at least through Northern Hemisphere spring 2010.

    Summary

    • El Niño is present across the equatorial Pacific Ocean.
    • Sea surface temperatures (SST) were at least 1.0ºC above-average across much of the central and east-central equatorial Pacific.
    • Based on current observations and dynamical model forecasts, El Niño is expected to strengthen and last at least through Northern Hemisphere spring 2010.

    Week 37 Volcano Watch

    Posted by feww on September 18, 2008

    10 September-16 September 2008

    New Activity/Unrest:

    Bagana, Bougainville Island, Papua New Guinea

    (September 16, 2008 ) Darwin VAAC analysis of satellite imagery revealed low-level ash plume from Bagana rising to an altitude of 2.4 km a.s.l., drifting SW.

    More information and a Geologic Summary of Bagana

    Bagana

    Latitude: 6°8’24″S, Longitude: 155°11’42″E

    Bagana volcano, occupying a remote portion of central Bougainville Island, is one of Melanesia’s youngest and most active volcanoes. Bagana is a massive symmetrical, roughly 1750-m-high lava cone largely constructed by an accumulation of viscous andesitic lava flows. The entire lava cone could have been constructed in about 300 years at its present rate of lava production. Eruptive activity at Bagana is frequent and is characterized by non-explosive effusion of viscous lava that maintains a small lava dome in the summit crater, although explosive activity occasionally producing pyroclastic flows also occurs. Lava flows form dramatic, freshly preserved tongue-shaped lobes up to 50-m-thick with prominent levees that descend the volcano’s flanks on all sides. (Image and caption: Global Volcanic Program.
