Tropical Cyclones - 0 views

  • In the western Pacific they are called typhoons, and in the southern hemisphere they are called cyclones.  But, no matter where they occur they represent the same process.
  • Tropical cyclones are dangerous because of their high winds, the storm surge produced as they approach a coast, and the severe thunderstorms associated with them. Although death due to hurricanes has decreased in recent years due to better methods of forecasting and establishment of early warning systems, the economic damage from hurricanes has increased as more and more development takes place along coastlines.
  • Warm ocean waters (of at least 26.5°C [80°F]) throughout about the upper 50 m of the tropical ocean must be present.  The heat in these warm waters is necessary to fuel the tropical cyclone. The atmosphere must cool fast enough with height, such that it is potentially unstable to moist convection. It is the thunderstorm activity which allows the heat stored in the ocean waters to be liberated and used for tropical cyclone development. The mid-troposphere (5 km [3 mi] altitude), must contain enough moisture to sustain the thunderstorms. Dry mid levels are not conducive to the continuing development of widespread thunderstorm activity. The disturbance must occur at a minimum distance of at least 500 km [300 mi] from the equator. For tropical cyclonic storms to occur, there is a requirement that the Coriolis force must be present.  Remember that the Coriolis effect is zero near the equator and increases to the north and south of the equator.  Without the Coriolis force, the low pressure of the disturbance cannot be maintained.

  • There must be a pre-existing near-surface disturbance that shows convergence of moist air and is beginning to rotate. Tropical cyclones cannot be generated spontaneously. They require a weakly organized system that begins to spin and has low level inflow of moist air. There must be low values (less than about 10 m/s [20 mph]) of vertical wind shear between the surface and the upper troposphere. Vertical wind shear is the rate of change of wind velocity with altitude.  Large values of vertical wind shear disrupt the incipient tropical cyclone by removing the rising moist air too quickly, preventing the development of the tropical cyclone. Or, if a tropical cyclone has already formed, large vertical shear can weaken or destroy it by interfering with the organization around the cyclone center.
  • unstable atmosphere
  • his instability increases the likelihood of convection, which leads to strong updrafts that lift the air and moisture upwards, creating an environment favorable for the development of high, towering clouds.
  • Surface convergence (indicated by the small horizontal arrows in the diagram below) causes rising motion around a surface cyclone (labeled as "L"). The air cools as it rises (vertical arrows) and condensation occurs.  The condensation of water vapor to liquid water releases the latent heat of condensation into the atmosphere. This heating causes the air to expand, forcing the air to diverge at the upper levels (horizontal arrows at cloud tops).
  • Since pressure is a measure of the weight of the air above an area, removal of air at the upper levels subsequently reduces pressure at the surface. A further reduction in surface pressure leads to increasing convergence (due to an higher pressure gradient), which further intensifies the rising motion, latent heat release, and so on. As long as favorable conditions exist, this process continues to build upon itself
  • When cyclonic circulation begins around the central low pressure area, and wind speeds reach 62 km/hr (39 mi/hr) the disturbance is considered a tropical storm and is given a name.  When wind speeds reach 119 km/hr (74 mi/hr) it becomes a hurricane.

Climate Prediction Center - Cold Episodes - 0 views

  • At times ocean surface temperatures in the equatorial Pacific are colder than normal. These cold episodes, sometimes referred to as La Niña episodes, are characterized by lower than normal pressure over Indonesia and northern Australia and higher than normal pressure over the eastern tropical Pacific. This pressure pattern is associated with enhanced near-surface equatorial easterly winds over the central and eastern equatorial Pacific.
  • bnormally cold waters in the equatorial central give rise to suppressed cloudiness and rainfall in that region, especially during the Northern Hemispherel winter and spring seasons. At the same time, rainfall is enhanced over Indonesia, Malaysia and northern Australia. Thus, the normal Walker Circulation during winter and spring, which features rising air, cloudiness and rainfall over the region of Indonesia and the western Pacific, and sinking air over the equatorial eastern Pacific, becomes stronger than normal.
  • Significant departures from normal are shown in the accompanying figures for the Northern Hemisphere winter and summer seasons.
  • ...1 more annotation...
  • During cold episodes, the colder than normal ocean temperatures in the equatorial central Pacific act to inhibit the formation of rain-producing clouds over that region. Wetter than normal conditions develop farther west over northern Australia, Indonesia and Malaysia, during the northern winter, and over the Philippines during the northern summer. Wetter than normal conditions are also observed over southeastern Africa and northern Brazil, during the northern winter season. During the northern summer season, the Indian monsoon rainfall tends to be greater than normal, especially in northwest India. Drier than normal conditions during cold episodes are observed along the west coast of tropical South America, and at subtropical latitudes of North America (Gulf Coast) and South America (southern Brazil to central Argentina) during their respective winter seasons.

  • The Kyoto Protocol was drawn up with the long term as the primary focus. In essence, the protocol assumes that what we really need to worry about is the climate in a century’s time, not today.
  • CO2 sticks around for about a century. Methane, the second most important greenhouse gas, generally lasts in the atmosphere for about a decade. But while it’s there it is many times more potent.
  • This “hundred-year rule” has the effect of downgrading the importance of methane, and giving only small credit to countries that try to cut methane emissions.
  • the protocol gives a country that reduces its methane emissions by a tonne 20 times as much credit as for reducing CO2 emissions by a tonne.
  • Cows can be given less gas-inducing feed. Leaks in gas pipelines can be plugged. And so on.
  • Technically, we are going to have to find many more ways of producing energy without burning fossil fuels – the so-called carbon-free economy. Politically, we are going to have to find a way of doing so which doesn’t affect the growing economies of the developing nations, whose responsibility for the build-up of greenhouse gases so far has been minimal. Some people think this will require moving towards equal pollution rights for every citizen on the planet, a policy endorsed by Britain’s Royal Commission on Environmental Pollution earlier this year.

We can question whether a man dressed in a parrot feather headdress and penis sheath is more valuable than one in a Batman T-shirt and gym shorts. But who can be blind to their knowledge of forest plants and animals or to the preeminent values of clean water, untainted air, and the genetic and cultural treasure of diversity itself?

Why Ebola is terrifying and dangerous: It preys on family, caregiving, and human bonds. - 0 views

  • 75 percent of Ebola victims are women, people who do much of the care work throughout Africa and the rest of the world. In short, Ebola parasitizes our humanity.
  • Its kill rate: In this particular outbreak, a running tabulation suggests that 54 percent of the infected die, though adjusted numbers suggest that the rate is much higher. Its exponential growth: At this point, the number of people infected is doubling approximately every three weeks, leading some epidemiologists to project between 77,000 and 277,000 cases by the end of 2014. The gruesomeness with which it kills: by hijacking cells and migrating throughout the body to affect all organs, causing victims to bleed profusely. The ease with which it is transmitted: through contact with bodily fluids, including sweat, tears, saliva, blood, urine, semen, etc., including objects that have come in contact with bodily fluids (such as bed sheets, clothing, and needles) and corpses. The threat of mutation: Prominent figures have expressed serious concerns that this disease will go airborne, and there are many other mechanisms through which mutation might make it much more transmissible.

The fisherman earns many times as much money as Kino fishermen, doesn’t have bycatch, and the fish makes for an amazing meal. Peckham says that when he first showed the fish to this restaurant, they refused to believe it was cabrilla.

  • visits an offset website, uses the online tools to calculate the emissions of their trip, and then pays the offset company to reduce emissions elsewhere in the world by the same amount – thus making the flight "carbon neutral".
  • £8/$12 for each tonne of CO2 offset
  • carbon neutrality included as part of the price.
  • most of the best-known carbon offset schemes have long-since switched from tree planting to clean-energy projects – anything from distributing efficient cooking stoves through to capturing methane gas at landfill sites.
  • many people argue that offsetting is unhelpful – or even counterproductive – in the fight against climate change
  • Just as indulgences allowed the rich to feel better about sinful behaviour without actually changing their ways, carbon offsets allow us to "buy complacency, political apathy and self-satisfaction"
  • "Our guilty consciences appeased, we continue to fill up our SUVs and fly round the world without the least concern about our impact on the planet … it's like pushing the food around on your plate to create the impression that you have eaten it."
  • "a positive approach to offsetting could have public resonance well beyond the CO2 offset, and would help to build awareness of the need for other measures."
  • This boils down not just to the effectiveness of the project at soaking up CO2 or avoiding future emissions. Effectiveness is important but not enough. You also need to be sure that the carbon savings are additional to any savings which might have happened anyway.
  • The carbon savings would only be classified as additional if the project managers could demonstrate that, for the period in which the carbon savings of the new lightbulbs were being counted, the recipients wouldn't have acquired low-energy bulbs by some other means.
  • The problem is that it's almost impossible to prove additionality with absolute certainly, as no one can be sure what will happen in the future,
  • If that happened, the bulbs distributed by the offset company would cease to be additional, since the energy savings would have happened even if the offset project had never happened.
  • To try and answer these questions, the voluntary offset market has developed various standards, which are a bit like the certification systems used for fairly traded or organic food
  • Voluntary Gold Standard (VGS) and the Voluntary Carbon Standard (VCS).
  • One VGS-certified biomass power plant refused to allow her around, though staff there reported a number of concerns such as trees being chopped down and sold to the plant, which was designed to run on agricultural wastes.
  • f we're to tackle climate change, they argue, the projects being rolled out by offset companies should be happening anyway, funded by governments around the world, while companies and individuals reduce their carbon footprints directly.
  • Only in this way – by doing everything possible to make reductions everywhere, rather than polluting in one place and offsetting in another – does the world have a good chance of avoiding runaway climate change, such critics claim.
  • some carbon-neutrality advocates suggest offsetting carbon-intensive activities such as flights two or three or even ten times ove
  • The point is simply that the world is full of inexpensive ways to reduce emissions. In theory, if enough people started offsetting, or if governments started acting seriously to tackle global warming, then the price of offsets would gradually rise, as the low-hanging fruit of emissions savings – the easiest and cheapest "quick wins" – would get used up.
