A jet stream coupling which occurs such that the subtropical jet out of Hawaii reaches Oregon is called the Pineapple Express. While this is rare occurrence, in recent years the frequency has increased (Greenhouse effect?) and this jet stream pattern was the cause of the 3 floods in the Willamette Valley in 1996. ... This most recent occurrence (1997) was mild compared to the one in late May 1993 which produced impressive thunderstorms and established the May precipitation record. ...

... Empirical and theoretical modeling of 3-D structures in the solar corona is confronted by the tremendous amount of data needed to represent phenomena with a large dynamic range both in size and magnitude, and with a rapid temporal evolution. Octree representation of the 3-D coronal electron distribution offers the right compromise between resolution and size, allowing computation of synthetic images of the solar corona. ... The time interval between images is one day. ...

... Meta Index / Home Page / Description The earthbarycen task converts times expressed in the local satellite frame to Barycentric Dynamical Time (TDB) at a given point on the Earth. ... The conversion of a satellite time tag to TDB requires the knowledge of the satellite's position at that time. ... In addition to the satellite position data, the time conversion algorithm in use by earthbarycen requires the barycentric vectors for the time period in question to be known a priori. ...
