Case 1 (Times: 2059 - 2302): This is an
anvil study. The aircraft was frequently on the edge of the anvil, and
other times close to the convection. Case 2 (Times: 2312 - 2325): This was a brief (single pass) in a convective region. |
000607 | 1755 - 1907 | TBD | Anvil | Case 1 (Times: 1815 - 1852): A few brief moments through anvils. Mostly this is a convective flight. |
000611 | 1758 - 2000 |
Sharon Lewis 020207 |
Anvil |
Case 1 (Times: 1810 - 1826): This is anvil
was just east of the 74C radar. There is no known lightning activity in
the cloud in the observable past. Cell is in decay. Case 2 (Times: 1828 - 1858): There was lightning activity in this cell about 1615. Last lightning was about 1705. Cell was in decay when the aircraft arrived. Aircraft flew on the edge of the anvil, not through the middle. Case 3 (Times: 1901 - 1955): There was no known lightning in this cell in the observable past. The part of the anvil studied was fairly close to the generating convection. |
000612 | 1415 - 1756 | TBD | NonAnvil |
Case 1 (Times: 1430 - 1730): Possibly a good
case to study decay of electric fields and/or debris. Case 2 (Times: 1730 - 1745): Aircraft was flying to the west of an active cell. |
000613 | 2016 - 2424 | TBD | Anvil | Case 1 (Times: 2045 - 2405): Good anvil study. Aircraft arrives in the early stages of anvil development and remains until little or no initiating convection is left. Lightning activity until 2145. |
000614 | 2058 - 2424 |
Sharon Lewis 021003 |
Anvil |
Case 1 (Times: 2127 - 2158): This is a
decaying anvil. The generating convection was gone before the aircraft
arrived. Case 2 (Times: 2212 - 2409): This case has multiple cells and multiple anvils. The anvil studied was a good case for studying the decay of an anvil. |
000617 | 1551 - 1724 | TBD | NonAnvil | Case 1 (Times: 1604 - 1724): This might be debris. |
000620 | 2132 - 2349 | TBD | NonAnvil |
Case 1 (Times: 2150 - 2227): This was
debris. Case 2 (Times: 2228 - 2332): This is mostly convection. |
000623 - 1 | 1636 - 1911 | TBD | NonAnvil |
Case 1 (Times: 1654 - 1718): The was out in
front of an electrically active part of the storm. Case 2 (Times: 1718 - 1744): This is debris. The core was electrically active at 1707. Case 3 (Times: 1748 - 1752): This is debris, although there was never really a strong core here. Case 4 (Times: 1756 - 1824): This is approximately the same position as Case 1. Given the eastward motion of the system, it is not the same cell. |
000623 - 2 | 2050 - 2115 | TBD | NonAnvil | Case 5 (Times: 2057 - 2110): This was a ferry flight. Most of the microphysics instruments were not turned on during this time. |
000624 - 1 | 1624 - 1958 | TBD | NonAnvil | Case 1 (Times: 1645 - 1945): This was an electrically active growing storm. |
000624 - 2 | 2044 - 2343 | TBD | NonAnvil |
Case 2 (Times: 2100 - 2113): Aircraft passed through some debris. Case 3 (Times: 2113 - 2225): Some 40dBZ areas appear at 4 km on the cappis along with some lightning activity. Case 4 (Times: 2225 - 2332): The lightning was reducing in amount while the aircraft was there. |
000625 | 1702 - 1817 | TBD | Anvil |
Case 1 (Times: 1710 - 1728): Just a simple,
little cell without much lightning activity. Case 2 (Times: 1728 - 1811): Anvil blowing off the the northeast. |
000628 - 1 | 1400 - 1511 |
Sharon Lewis 020502 |
Anvil |
Case 1 (Times: 1404 - 1425): Last lightning
occurred about 1305. It is possible the lightning that occurs at 1427,
at (-40,-10) is this same cell. Case 2 (Times: 1425 - 1456): Last lightning occurred about 1305. |
000628 - 2 | 1809 - 2135 |
Sharon Lewis 020502 |
Anvil |
Case 3 (Times: 1815 - 1837): The "core" for
this case is directly over the radar, inside the "radar void". Case 4 (Times: 1837 - 2000): The aircraft missed most of the anvil for this case. It was usually sampled when the aircraft was turning around. Case 5 (Times: 2003 - 2118): The aircraft remained too close to the core when sampling this anvil case. |

Jim Dye 021016 |
NonAnvil | Case 1 (Times: 2133 - 2427): There was a moderate amount of lightning before the aircraft arrived and the last lightning occurred in the early part of the flight. |
010525 | 1829 - 2213 |
Phil Krider Natalie Murray 020627 |
Anvil |
Case 1 (Times: 1853 - 1913): The was a
small anvil on the northern edge of the line. Case 2 (Times: 1913 - 1931): If you go back to 1834 you will see that there was convection in the area, thus it was a debris cloud. Case 3 (Times: 1931 - 1938): This part of the study was at the opposite end to the development of the convection. Case 4 (Times: 1938 - 1944): This might be the same debris as case 2. Case 5 (Times: 1944 - 2038): This is debris from the convective part of case 1. The aircraft might have been flying through some anvil after 2014. Case 6 (Times: 2028 - 2200): Aircraft was flying close to convection. |
010527 | 2125 - 2437 |
Monte Bateman 020221 |
Anvil |
Case 1 (Times: 2135 - 2201): Early stage of
developing anvil. Case 2 (Times: 2201 - 2222): This looks to have been part of the anvil studied in Case 1 that broke away, but the MER plots suggest it is debris. Did it dissipate, or was it consumed by a larger, growing anvil? Case 3 (Times: 2222 - 2322): The anvil that collided with CAse 2. The flight covers more than one "finger" of the anvil. Case 4 (Times: 2322 - 2409): This is a well developed 25-35 dBZ region at 4 km. It briefly develops a 35 dBZ region at about 2346. Case 5 (Times: 2409 - 2422): This is the anvil associated with the decaying cell of Case 4. |
010528 | 1802 - 2202 |
Monte Bateman (date unknown) |
Anvil | Case 1 (Times: 1806 - 211120): Anvil attached to core initially producing lightning then decaying with time. |
010529 | 1939 - 2248 |
Monte Bateman 020516 |
Anvil | Case 1 (Times: 2006 - 2231): Small anvil attached to a long lasting active core. During the earlier part of the flight the aircraft was flying very close to the convection. |
010602 | 1839 - 2258 |
Tony Grainger 020418 |
Anvil | Case 1 (Times: 1914 - 2238): This is a rather large system. It might be more than one cell, but shortly after the aircraft arrived the was one dominant cell that as a large 45 dBZ region at 10 km. |
010604 | 1840 - 2314 |
Jim Dye 020124 |
Anvil |
ase 1 (Times: 1901 - 1908): This shows
precip going to the ground, but no cores. Case 2 (Times: 1908 - 1921): This is very close to the radar data void and rather small so we can't really say much about it. Case 3 (Times: 1921 - 1928): It is possible this anvil is from the cell studied in Case 1. Case 4 (Times: 1928 - 2010): At this time this is a separate cell with some lightning. It will soon be taken over by the one to the south. This anvil becomes detached at about 2003. Case 5 (Times: 2010 - 2259): This cell started off a moderate size when the aircraft took off, but it grew. The >= 45 dBZ region in the 4 km level at 2009 is abotu 40kmx30km with maximum > 60 dBZ. |
010605 | 1759 - 2154 |
Eric Defer 020124 |
NonAnvil |
Case 1 (Times: 1820 - 1846 ): decayed
convection. Last lightning about 1719 in this cell. Case 2 (Times: 1853 - 1928 ) Althought the core is no longer at the position of the aircraft by looking at the animation it can be seen that the core was in this position. Case 3 (Times: 1938 - 2044 ): A reverse search from the aircraft position shows that the core was there in the recent past. Case 4 (Times: 2044 - 2116): Again, a core was at this location in the recent past. |
010606 | 1733 - 2035 |
Natalie Murray 020307 |
NonAnvil |
Case 1 (Times: 1749 - 1815): a mass of
several cells Case 2 (Times: 1815 - 1921): debris Case 3 (Times: 1921 - 2005): debris Case 4 (Times: 2009 - 2020): moderate convection of multiple cells |
010607 | 1717 - 2027 | TBD | NonAnvil |
Case 1 (Times: 1729 - 1936): t looks like
this slows down as it approaches the coast. Case 2 (Times: 1937 - 1950): anvil with no convecton Case 3 (Times: 1950 - 2008): This used to be the convection that created the anvil in Case 2 Case 4 (Times: 2009 - 2017): Back through case 1? |
010610 | 1958 - 2346 |
Tony Grainger 020110 |
Anvil |
Case 1 (Times: 2008 - 2042): A little bit of
anvil at 2025, and some low level stuff at takeoff. Mostly this time
fram is around convection with a lot of lightning. Case 2 (Times: 2042 - 2133): Much of this is flown very close to the source. Case 3 (Times: 2133 - 2210) : There was lightning associated with this part of the cloud about 2109 and bases are at leaste down to the 4km level. The last lightning in this part of the line was about 2130. Case 4 (Times: 2210 - 2311): The aircraft does get close to the source about 2237 and 2240. Case 5 (Times: 2311 - 2345) : Landing. |
010615 | 2106 - 2406 |
Jim Dye 020321 |
Anvil |
Case 1 (Times: 2120 - 2146): complex cumulus
Case 2 (Times: 2146 - 2252): anvil in weakening line of convection Case 3 (Times: 2252 - 2347): The reflectivity appears to stop at the radar. Perhaps due to some coastal effect? |
010618 | 2007 - 2220 |
Paul Willis 020404 |
NonAnvil | Case 1 (Times: 2032 - 2203): There was lightning in a cell to the west of the aircraft. There was 45-50 dBZ reflectivity with lightning in the region the aircraft flew at 1844. There is really no storm motion so this is debris. |
* 010623 | 1816 - 2008 | TBD | NonAnvil | Case 1 (Times: 1824 - 2006): This started off as a complex, cumulus of multiple cells with lightning. By the time the aircraft got there any reflectivity > 35dBZ was a good 75 km away and the radar screen is better described at "disturbed weather" (i.e. wide spread, sometimes pretty deep, "stuff") |
010624 | 1757 - 2027 |
Frank Merceret 020919 |
Anvil | Case 1 (Times: 1804 - 2024): The LDAR goes out about the time the aircraft arrives. The convective line is in an arc shape where the top of the arc and the bottom of the arc do not move in the same way. |
010625 | 1920 - 2220 |
Eric Defer 020110 |
Anvil |
Case 1 (Times: 1952 - 204810): When the
aircraft arrives at the anvil to cell 1 the cell itself is gone. The
system is in decay and by 2140 the anvil is gone. Case 2 (Times: 204820 - 2215): The aircraft flew way below the anvil associated with the 2nd cell which developed after the first. |
010627 | 1434 - 1733 | TBD | Anvil |
Case 1 (Times: 1450 - 1457): The aircraft
enters into the mass of cores. Case 2 (Times: 1457 - 1615): The anvil is growing at this time and the maximums in the microphysics are probably due to close proximity to cores during turn arounds. Case 3 (Times: 1615 - 1732): Again the aircraft turns around in cores. This is another part of the cloud system and probably has a different anvil source. |
010628 | 1917 - 2127 |
Monte Bateman 020905 |
NonAnvil |
Case 1 (Times: 1925 - 2032): thick cloud, no
convection Case 2 (Times: 2032 - 2125): The aircraft is in another part of the cloud and way below it. |
