摘要:
A spectacular explosion (Figure 1) beneath Ruapehu Crater Lake on September 23, 1995, ejected lake water, rocks, and scoria bombs onto the summit of snow‐covered Ruapehu volcano and sent lahars (mudflows) down its outer slopes. Eruptions continued into October, completely emptying the ˜107m3lake, and dispersing ˜0.1 km3of ash and scoria downwind. While this ejecta volume is relatively small, Ruapehu is the only major ski resort in the North Island of New Zealand and it attracts up to 10,000 skiers on some days. Chair lifts and tows (Figure 2) carry skiers to within 2 km of the summit crater through areas affected by lahars during eruptions in 1969 and 1975. The 1995 eruption episode dramatically demonstrated volcanic hazards at Ruapehu to a largely unaware pub

摘要:
Scale Issues in Hydrological Modelingis a collection of 27 papers presented at a workshop in Australia in 1993 and later published in two special issues ofHydrological Processes. It is one of the few books that addresses the scaling problem in hydrology: that is, how to transfer information from one scale to another and how to handle spatial heterogeneity. It gives us a flavor of the nature and extent of the scaling problems in hydrology, although no general answers are provided.

摘要:
Thirty years ago an important investigation was conducted that could be used today as a benchmark experiment for measuring long‐term global temperature changes. In fact, such an approach could be the most cost‐effective method for providing the scientific community with rapid and reliable evidence for or against global warm

摘要:
The Sun may be less boisterous now than it was in 1989 or than it will be in 2000, but it is anything but quiet. In fact, the first images returned this spring from the Solar and Heliospheric Observatory (SOHO) reveal a Sun that is quite active even though it has waned to its solar minimum.“Movies made from SOHO ultraviolet data show that there is continuous motion and action everywhere on the Sun,” said Joseph Gurman, an astrophysicist from NASA's Goddard Space Flight Center and coinvestigator for SOHO's extreme ultraviolet imaging telescope (EIT). “Even at the quietest places on the Sun, including the so‐called coronal holes, there is a tremendous amount of activity… a general twinkling everywhere
