I am not in the least bit surprised. This is an ecological nightmare of epic proportions. Acid rain is nothing compared to this.
Yeah every street here in MT looks like that the first few min of a rain storm. That's why they say the slickest period is the first 5 min the rain is coming down. Byte
main roads, sure.. I've yet to see this kind of rainbow on my neighborhood street. Aside from that, they've already mentioned concern for heavy rain, hurricane etc type weather spreading oil hydrocarbons around. Could it be purely from automobiles? sure.. but I won't be so quick to discount that this is true considering the size and reach of the slick.
Insufficient data!!! Reanalysis required. Resistance is futile. Comply immediately or be assimilated.
No offense to Tango, but the internet is full of propagandizing morons. Try not to get caught up in their trolling. I think that what we need right now is sensible, honest reporting. Can't blame you for falling for this one, Tango. The Gulf incident is going to continue to get worse.
Now, don't get too far with the water cycle, rain will carry down contaminants. Like, for example, oily particles getting into the atmosphere from burning off the oil at sea. (But I still think it's drips from the redneck cars.)
tornadoes, or water spouts, and such violent storms can pick up things one would never imagine and carry it quite some way before showering the earth with it. ... ie frogs and fish. I don't think it's that much of a stretch to think that maybe surface oil sludge could get sucked up and deposited in coastal areas with rainfall as well.
I think that is the concern with the tropical storms rolling in. My immediate concern is the formation of azeotrope's which are complex mixtures of two liquids which cannot be separated by distillation. There is your "oil-rain".
Funny how we've had so many oil spills around the globe and apparently now is the first reports of oil rain? Me thinks the trailer parkers are wanting some BP $. If this was a reasonable assumption, it would occur more frequently. <TABLE cellSpacing=2 cellPadding=0 border=0><TBODY><TR><TD vAlign=bottom>Name</TD><TD></TD><TD>Molecular Formula </TD><TD></TD><TD>Melting Point (<SUP>o</SUP>C) </TD><TD></TD><TD>Boiling Point (<SUP>o</SUP>C) </TD><TD></TD><TD>State at 25<SUP>o</SUP>C </TD></TR><TR><TD>methane</TD><TD></TD><TD>CH<SUB>4</SUB></TD><TD></TD><TD>-183</TD><TD></TD><TD>-164</TD><TD></TD><TD>gas</TD></TR><TR><TD>ethane</TD><TD></TD><TD>C<SUB>2</SUB>H<SUB>6</SUB></TD><TD></TD><TD>-183</TD><TD></TD><TD>-89</TD><TD></TD><TD></TD></TR><TR><TD>propane</TD><TD></TD><TD>C<SUB>3</SUB>H<SUB>8</SUB></TD><TD></TD><TD>-190</TD><TD></TD><TD>-42</TD><TD></TD><TD></TD></TR><TR><TD>butane</TD><TD></TD><TD>C<SUB>4</SUB>H<SUB>10</SUB></TD><TD></TD><TD>-138</TD><TD></TD><TD>-0.5</TD><TD></TD><TD></TD></TR><TR><TD>pentane</TD><TD></TD><TD>C<SUB>5</SUB>H<SUB>12</SUB></TD><TD></TD><TD>-130</TD><TD></TD><TD>36</TD><TD></TD><TD></TD></TR><TR><TD>hexane</TD><TD></TD><TD>C<SUB>6</SUB>H<SUB>14</SUB></TD><TD></TD><TD>-95</TD><TD></TD><TD>69</TD><TD></TD><TD></TD></TR><TR><TD>heptane</TD><TD></TD><TD>C<SUB>7</SUB>H<SUB>16</SUB></TD><TD></TD><TD>-91</TD><TD></TD><TD>98</TD><TD></TD><TD></TD></TR><TR><TD>octane</TD><TD></TD><TD>C<SUB>8</SUB>H<SUB>18</SUB></TD><TD></TD><TD>-57</TD><TD></TD><TD>125</TD><TD></TD><TD></TD></TR><TR><TD>nonane</TD><TD></TD><TD>C<SUB>9</SUB>H<SUB>20</SUB></TD><TD></TD><TD>-51</TD><TD></TD><TD>151</TD><TD></TD><TD>liquid</TD></TR><TR><TD>decane</TD><TD></TD><TD>C<SUB>10</SUB>H<SUB>22</SUB></TD><TD></TD><TD>-30</TD><TD></TD><TD>174</TD><TD></TD><TD></TD></TR><TR><TD>undecane</TD><TD></TD><TD>C<SUB>11</SUB>H<SUB>24</SUB></TD><TD></TD><TD>-25</TD><TD></TD><TD>196</TD><TD></TD><TD></TD></TR><TR><TD>dodecane</TD><TD></TD><TD>C<SUB>12</SUB>H<SUB>26</SUB></TD><TD></TD><TD>-10</TD><TD></TD><TD>216</TD><TD></TD><TD></TD></TR><TR><TD>eicosane</TD><TD></TD><TD>C<SUB>20</SUB>H<SUB>42</SUB></TD><TD></TD><TD>37</TD><TD></TD><TD>343</TD><TD></TD><TD></TD></TR><TR><TD>triacontane</TD><TD></TD><TD>C<SUB>30</SUB>H<SUB>62</SUB></TD><TD></TD><TD>66</TD><TD></TD><TD>450</TD><TD></TD><TD>solid</TD></TR></TBODY></TABLE> So the hydrocarbons larger than 6 carbons need a temp of about 212 F or more to boil. The ones lower than 6 are typically gases any way.
reason this is definately from the road oil is that the trailer pad doesn't have the rainbow on it. If it were really oil rain, lol then it'd be everywhere and not just the road.
