| Zusammenfassung |
| On short timescales, the effect of deep convection on the tropical atmosphere
is to heat the upper troposphere and cool the lower troposphere. This
stratiform temperature response to deep convection gives rise to a local
maximum in stability near the melting level. We use temperature measurements
from five radiosonde stations in the Western Tropical Pacific, from the
Stratospheric Processes and their Role in Climate (SPARC) archive, to examine
the response of this mid-tropospheric stability maximum to changes in surface
temperature. We find that the height of the stability maximum increases when
the surface temperature increases, by an amount roughly equal to the upward
displacement of the 0 °C melting level. Although this response was
determined using monthly mean temperature anomalies from an 10 yr record
(1999–2008), we use model results to show that a similar response should
also be expected on longer timescales. |
