Major uncertainties in the weather simulation are generated by uncertainties in the initial conditions, which are obtained from the observation.
Despite the initial warm weather, I looked upstream along the Thames to notice that the squally nature of the tail end of the hurricane was sending a band of rain our way.
"Given similar initial weather conditions, we don't know why some storms produce downpours while others contain just as much water vapor but make very little or no rain," Dr. Weisman said.
N.O.A.A.'s Storm Prediction Center reports that many different initial weather conditions can lead to tornadoes, but — most perplexing of all — those same conditions frequently produce no tornadoes whatsoever.
Initial weathering took place in the last interglacial period, under wetter conditions during which the Tertiary basalts were strongly weathered, leaving corestones in a saprolitic, oxidized mass.
This study highlights the importance of carbonate weathering in alpine biogeochemical cycling during the initial stage of weathering in granitoid rock areas.
Koritnig (1951) suggested that F− is leached in the initial stages of weathering of granite massifs.
However, knowledge on the initial stages of weathering at the decadal time scale is limited.
All of the initial lenses will be weather resistant for more rugged shooting conditions.
